+ MyNewt is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.

+ MyNewt is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.

+<p>Device drivers in the Mynewt context includes libraries that interface with devices external to the CPU.

+<ul>
+<li>
+<p>The Board Support Package (BSP) abstracts board specific configurations e.g. CPU frequency, input voltage, LED pins, on-chip flash map etc.</p>
+</li>
+<li>
+<p>The Hardware Abstraction Layer (HAL) abstracts architecture-specific functionality. It initializes and enables components within a master processor. It is designed to be portable across all the various MCUs supported in Mynewt (e.g. Nordic's nRF51, Nordic's nRF52, NXP's MK64F12 etc.). It includes code that initializes and manages access to components of the board such as board buses (I2C, PCI, PCMCIA, etc.), off-chip memory (controllers, level 2+ cache, Flash, etc.), and off-chip I/O (Ethernet, RS-232, display, mouse, etc.)</p>
+</li>
+<li>
+<p>The driver sits atop the BSP and HAL. It abstracts the common modes of operation for each peripheral device connected via the standard interfaces to the processor. There may be multiple driver implementations of differing complexities for a particular peripheral device. For example, for an Analog to Digital Converter (ADC) peripheral you might have a simple driver that does blocking ADC reads and uses the HAL only. You might have a more complex driver that can deal with both internal and external ADCs, and has chip specific support for doing things like DMA\u2019ing ADC reads into a buffer and posting an event to a task every \u2019n\u2019 samples. The drivers are the ones that register with the kernel\u2019s power management APIs, and manage turning on and off peripherals and external chipsets, etc. The Mynewt core repository comes with a base set of drivers to help the user get started.</p>
+</li>
+</ul>
+<h3 id="general-design-principles">General design principles</h3>
+<ul>
+<li>
+<p>Device drivers should have a consistent structure and unified interface whenever possible. For example, we have a top-level package, \u201cadc\u201d, which contains the interface for all ADC drivers, and then we have the individual implementation of the driver itself. The following source files point to this:</p>
+<ul>
+<li>high-level ADC API: <code>hw/drivers/adc/include/adc/adc.h</code> </li>
+<li>implementation of ADC for STM32F4: <code>hw/drivers/adc/adc_stm32f4/src/adc_stm32f4.c</code> (As of the 1.0.0-beta release, ADC for nRF51 and nRF52 are available at an external <a href="https://github.com/runtimeinc/mynewt_nordic/tree/master/hw/drivers/adc">repo</a>. They are expected to be pulled into the core repo on Apache Mynewt after the license terms are clarified.). The only exported call in this example is <code>int stm32f4_adc_dev_init(struct os_dev *, void *)</code> which is passed as a function pointer to <code>os_dev_create()</code> in <code>hal_bsp.c</code>, when the adc device is created.</li>
+</ul>
+</li>
+<li>
+<p>Device drivers should be easy to use. In Mynewt, creating a device initializes it as well, making it readily available for the user to open, use (e.g. read, configure etc.) and close. Creating a device is simple using <code>os_dev_create(struct os_dev *dev, char *name, uint8_t stage, uint8_t priority, os_dev_init_func_t od_init, void *arg)</code>. The <code>od_init</code> function is defined within the appropriate driver directory e.g. <code>stm32f4_adc_dev_init</code> in <code>hw/drivers/adc/adc_stm32f4/src/adc_stm32f4.c</code> for the ADC device initialization function. </p>
+</li>
+<li>
+<p>The implementation should allow for builds optimized for minimal memory usage. Additional functionality can be enabled by writing a more complex driver (usually based on the simple implementation included by default in the core repository) and optionally compiling the relevant packages in. Typically, only a basic driver that addresses a device\u2019s core functionality (covering ~90% of use cases) is included in the Mynewt core repository, thus keeping the footprint small.</p>
+</li>
+<li>
+<p>The implementation should allow a user to be able to instantiate multiple devices of a certain kind. In the Mynewt environment the user can, for example, maintain separate contexts for multiple ADCs over different peripheral connections such as SPI, I2C etc. It is also possible for a user to use a single peripheral interface (e.g. SPI) to drive multiple devices (e.g. ADC), and in that case the device driver has to handle the proper synchronization of the various tasks. </p>
+</li>
+<li>
+<p>Device drivers should be MCU independent. In Mynewt, device creation and operation functions are independent of the underlying MCU. </p>
+</li>
+<li>
+<p>Device drivers should be able to offer high-level interfaces for generic operations common to a particular device group. An example of such a class or group of devices is a group for sensors with generic operations such as channel discovery, configure, and read values. The organization of the driver directory is work in progress - so we encourage you to hop on the dev@ mailing list and offer your insights!</p>
+</li>
+<li>
+<p>Device drivers should be searchable. The plan is to have the newt tool offer a <code>newt pkg search</code> capability. This is work in progress. You are welcome to join the conversation on the dev@ mailing list!</p>
+</li>
+</ul>
+<h3 id="example">Example</h3>
+<p>The Mynewt core repo includes an example of a driver using the HAL to provide extra functionality - the UART driver. It uses HAL GPIO and UART to provide multiple serial ports on the NRF52 (but allowed on other platforms too.)</p>
+<p>The gist of the driver design is that there is an API for the driver (for use by applications), and then sub-packages to that driver that implement that driver API using the HAL and BSP APIs.</p>

+ MyNewt is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.

<h1 id="hardware-abstraction-layer">Hardware Abstraction Layer</h1>
<h3 id="description">Description</h3>
-<p>The Hardware Abstraction Layer (HAL) includes a set of APIs
-(Application Programmer Interface) to connect to
-the underlying hardware components including MCU components and peripheral
-components.</p>
-<p>The goal is to allow libraries, modules and applications written for Mynewt to
-be shared within the Mynewt community and used across the variety of supported
-Mynewt platforms. A secondary goal is to provide a simple consistent API
-to commonly used MCU components and peripherals to make development easier.
-Nothing in the HAL precludes the user of the underlying physical devices,
-it only limits the portability of the end application.</p>
+<p>The Hardware Abstraction Layer (HAL) in Mynewt is a low-level, base peripheral abstraction. HAL provides a core set of services that is implemented for each MCU supported by Mynewt. Device drivers are typically the software libraries that initialize the hardware and manage access to the hardware by higher layers of software. In the Mynewt OS, the layers can be depicted in the following manner.</p>

+<p>The Board Support Package (BSP) abstracts board specific configurations e.g. CPU frequency, input voltage, LED pins, on-chip flash map etc.</p>
+</li>
+<li>
+<p>The Hardware Abstraction Layer (HAL) abstracts architecture-specific functionality. It initializes and enables components within a master processor. It is designed to be portable across all the various MCUs supported in Mynewt (e.g. Nordic's nRF51, Nordic's nRF52, NXP's MK64F12 etc.). It includes code that initializes and manages access to components of the board such as board buses (I2C, PCI, PCMCIA, etc.), off-chip memory (controllers, level 2+ cache, Flash, etc.), and off-chip I/O (Ethernet, RS-232, display, mouse, etc.)</p>
+</li>
+<li>
+<p>The driver sits atop the BSP and HAL. It abstracts the common modes of operation for each peripheral device connected via the standard interfaces to the processor. There may be multiple driver implementations of differing complexities for a particular peripheral device. The drivers are the ones that register with the kernel\u2019s power management APIs, and manage turning on and off peripherals and external chipsets, etc. </p>

+<h3 id="general-design-principles">General design principles</h3>

+<li>
+<p>The HAL API should be simple. It should be as easy to implement for hardware as possible. A simple HAL API makes it easy to bring up new MCUs quickly.</p>

+<p>The HAL API should portable across all the various MCUs supported in Mynewt (e.g. Nordic's nRF51, Nordic's nRF52, NXP's MK64F12 etc.).</p>

<h3 id="example">Example</h3>
-<p>A Mynewt contributor might write a light-switch
-module (<code>libs/light</code>) that provides the functionality of an intelligent light
-switch. This might involve using a timer, a General Purpose Output (GPO)

-<p>ADCs have different conversion rates, resolution (bits) and reference voltages.</p>
-<p>The HAL_ADC has APIs to allow the application or library to query the capabilities
-of a specific ADC.</p>

-<th><strong>Method Name</strong></th>
-<th><strong> Description </strong></th>
-</tr>
-</thead>
-<tbody>
-<tr>
-<td>hal_adc_get_bits</td>
-<td>gets the resolution of the ADC in bits. For example if the ADC is 10 bits, a read will return a value from 0 through 2^10 - 1 = 1023.</td>
-</tr>
-<tr>
-<td>hal_adc_get_ref_mv</td>
-<td>gets the underlying reference voltage for the ADC in millivolts. For example, if the ADC is 10 bits and the reference voltage is 5000 mV a ADC reading of 1023 corresponds to 5V; a ADC reading of 0 corresponds to 0 volts.</td>
-</tr>
-</tbody>
-</table>
-<p>Given this information, the application or library could convert any reading
-to millivolts. Since this is a common operation, the HAL_ADC API has a helper
-function to perform this function: <code>hal_adc_to_mv()</code>.</p>
-<p>The current HAL_ADC API provides a blocking read command to initiate an ADC
-conversion, and return the result of that conversion. Conversion time is
-hardware dependent, but this is not an instantaneous operation. Libraries
-can use the <a href="../../hal_cputime/hal_cpu_timer/">hal_cputime</a> APIs to
-time conversions if that is relevant to the application.</p>
-<p>Future HAL_ADC APIs will include periodic ADC conversion, non-blocking ADC
-conversion and direct-to-memory DMA conversion. </p>

- MyNewt is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.

+ MyNewt is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.

+<p>Watchdog needs to be then started with a call to <code>hal_watchdog_enable()</code>.

+ MyNewt is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.

+<p>Device drivers in the Mynewt context includes libraries that interface with devices external to the CPU. These devices are connected to the CPU via standard peripherals such as SPI, GPIO, I2C etc. Device drivers leverage the base HAL services in Mynewt to provide friendly abstractions to application developers. </p>

+<ul>
+<li>
+<p>The Board Support Package (BSP) abstracts board specific configurations e.g. CPU frequency, input voltage, LED pins, on-chip flash map etc.</p>
+</li>
+<li>
+<p>The Hardware Abstraction Layer (HAL) abstracts architecture-specific functionality. It initializes and enables components within a master processor. It is designed to be portable across all the various MCUs supported in Mynewt (e.g. Nordic's nRF51, Nordic's nRF52, NXP's MK64F12 etc.). It includes code that initializes and manages access to components of the board such as board buses (I2C, PCI, PCMCIA, etc.), off-chip memory (controllers, level 2+ cache, Flash, etc.), and off-chip I/O (Ethernet, RS-232, display, mouse, etc.)</p>
+</li>
+<li>
+<p>The driver sits atop the BSP and HAL. It abstracts the common modes of operation for each peripheral device connected via the standard interfaces to the processor. There may be multiple driver implementations of differing complexities for a particular peripheral device. For example, for an Analog to Digital Converter (ADC) peripheral you might have a simple driver that does blocking ADC reads and uses the HAL only. You might have a more complex driver that can deal with both internal and external ADCs, and has chip specific support for doing things like DMA\u2019ing ADC reads into a buffer and posting an event to a task every \u2019n\u2019 samples. The drivers are the ones that register with the kernel\u2019s power management APIs, and manage turning on and off peripherals and external chipsets, etc. The Mynewt core repository comes with a base set of drivers to help the user get started.</p>
+</li>
+</ul>
+<h3 id="general-design-principles">General design principles</h3>
+<ul>
+<li>
+<p>Device drivers should have a consistent structure and unified interface whenever possible. For example, we have a top-level package, \u201cadc\u201d, which contains the interface for all ADC drivers, and then we have the individual implementation of the driver itself. The following source files point to this:</p>
+<ul>
+<li>high-level ADC API: <code>hw/drivers/adc/include/adc/adc.h</code> </li>
+<li>implementation of ADC for STM32F4: <code>hw/drivers/adc/adc_stm32f4/src/adc_stm32f4.c</code> (As of the 1.0.0-beta release, ADC for nRF51 and nRF52 are available at an external <a href="https://github.com/runtimeinc/mynewt_nordic/tree/master/hw/drivers/adc">repo</a>. They are expected to be pulled into the core repo on Apache Mynewt after the license terms are clarified.). The only exported call in this example is <code>int stm32f4_adc_dev_init(struct os_dev *, void *)</code> which is passed as a function pointer to <code>os_dev_create()</code> in <code>hal_bsp.c</code>, when the adc device is created.</li>
+</ul>
+</li>
+<li>
+<p>Device drivers should be easy to use. In Mynewt, creating a device initializes it as well, making it readily available for the user to open, use (e.g. read, configure etc.) and close. Creating a device is simple using <code>os_dev_create(struct os_dev *dev, char *name, uint8_t stage, uint8_t priority, os_dev_init_func_t od_init, void *arg)</code>. The <code>od_init</code> function is defined within the appropriate driver directory e.g. <code>stm32f4_adc_dev_init</code> in <code>hw/drivers/adc/adc_stm32f4/src/adc_stm32f4.c</code> for the ADC device initialization function. </p>
+</li>
+<li>
+<p>The implementation should allow for builds optimized for minimal memory usage. Additional functionality can be enabled by writing a more complex driver (usually based on the simple implementation included by default in the core repository) and optionally compiling the relevant packages in. Typically, only a basic driver that addresses a device\u2019s core functionality (covering ~90% of use cases) is included in the Mynewt core repository, thus keeping the footprint small.</p>
+</li>
+<li>
+<p>The implementation should allow a user to be able to instantiate multiple devices of a certain kind. In the Mynewt environment the user can, for example, maintain separate contexts for multiple ADCs over different peripheral connections such as SPI, I2C etc. It is also possible for a user to use a single peripheral interface (e.g. SPI) to drive multiple devices (e.g. ADC), and in that case the device driver has to handle the proper synchronization of the various tasks. </p>
+</li>
+<li>
+<p>Device drivers should be MCU independent. In Mynewt, device creation and operation functions are independent of the underlying MCU. </p>
+</li>
+<li>
+<p>Device drivers should be able to offer high-level interfaces for generic operations common to a particular device group. An example of such a class or group of devices is a group for sensors with generic operations such as channel discovery, configure, and read values. The organization of the driver directory is work in progress - so we encourage you to hop on the dev@ mailing list and offer your insights!</p>
+</li>
+<li>
+<p>Device drivers should be searchable. The plan is to have the newt tool offer a <code>newt pkg search</code> capability. This is work in progress. You are welcome to join the conversation on the dev@ mailing list!</p>
+</li>
+</ul>
+<h3 id="example">Example</h3>
+<p>The Mynewt core repo includes an example of a driver using the HAL to provide extra functionality - the UART driver. It uses HAL GPIO and UART to provide multiple serial ports on the NRF52 (but allowed on other platforms too.)</p>
+<p>The gist of the driver design is that there is an API for the driver (for use by applications), and then sub-packages to that driver that implement that driver API using the HAL and BSP APIs.</p>

+ MyNewt is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.

<h1 id="hardware-abstraction-layer">Hardware Abstraction Layer</h1>
<h3 id="description">Description</h3>
-<p>The Hardware Abstraction Layer (HAL) includes a set of APIs
-(Application Programmer Interface) to connect to
-the underlying hardware components including MCU components and peripheral
-components.</p>
-<p>The goal is to allow libraries, modules and applications written for Mynewt to
-be shared within the Mynewt community and used across the variety of supported
-Mynewt platforms. A secondary goal is to provide a simple consistent API
-to commonly used MCU components and peripherals to make development easier.
-Nothing in the HAL precludes the user of the underlying physical devices,
-it only limits the portability of the end application.</p>
+<p>The Hardware Abstraction Layer (HAL) in Mynewt is a low-level, base peripheral abstraction. HAL provides a core set of services that is implemented for each MCU supported by Mynewt. Device drivers are typically the software libraries that initialize the hardware and manage access to the hardware by higher layers of software. In the Mynewt OS, the layers can be depicted in the following manner.</p>

+<p>The Board Support Package (BSP) abstracts board specific configurations e.g. CPU frequency, input voltage, LED pins, on-chip flash map etc.</p>
+</li>
+<li>
+<p>The Hardware Abstraction Layer (HAL) abstracts architecture-specific functionality. It initializes and enables components within a master processor. It is designed to be portable across all the various MCUs supported in Mynewt (e.g. Nordic's nRF51, Nordic's nRF52, NXP's MK64F12 etc.). It includes code that initializes and manages access to components of the board such as board buses (I2C, PCI, PCMCIA, etc.), off-chip memory (controllers, level 2+ cache, Flash, etc.), and off-chip I/O (Ethernet, RS-232, display, mouse, etc.)</p>
+</li>
+<li>
+<p>The driver sits atop the BSP and HAL. It abstracts the common modes of operation for each peripheral device connected via the standard interfaces to the processor. There may be multiple driver implementations of differing complexities for a particular peripheral device. The drivers are the ones that register with the kernel\u2019s power management APIs, and manage turning on and off peripherals and external chipsets, etc. </p>

+<p>The HAL API should be simple. It should be as easy to implement for hardware as possible. A simple HAL API makes it easy to bring up new MCUs quickly.</p>

- MyNewt is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.

+<p>Individual GPIOs are referenced in the APIs as <code>pins</code>. However, in this interface the <code>pins</code> are virtual GPIO pins. The MCU header file maps these virtual <code>pins</code> to the physical GPIO ports and pins.</p>
<p>Typically, the BSP code may define named I/O pins in terms of these virtual <code>pins</code> to describe the devices attached to the physical pins.</p>

<p>Suppose my product uses the stm32F4xx processor. There already exists support for this processor within Mynewt. The processor has N ports (A,B,C..) of 16 GPIO pins per port. The MCU hal_gpio driver maps these to a set of virtual pins 0-N where port A maps to 0-15, Port B maps to 16-31, Port C maps to 32-47 and so on. The exact number of physical port (and virtual

<h1 id="using-hal-in-your-libraries">Using HAL in Your Libraries</h1>
<p>This page describes the recommended way to implement libraries that
utilize HAL functionality.</p>
-<p>Consider the light switch example from the <a href="../hal/">HAL overview</a> page.</p>
-<p>The light switch module needs a GPIO pin to set
-the light switch to on or off. The module declares that the GPIO to
-control the light switch is declared elsewhere in one of two methods.</p>
-<div class="codehilite" style="background: #ffffff"><pre style="line-height: 125%"> extern const int light_switch_gpio;
-</pre></div>
-
-
-<p>or</p>
-<div class="codehilite" style="background: #ffffff"><pre style="line-height: 125%"> extern int bsp_light_app_get_light_gpio();
-</pre></div>
-
-
-<p>Which method a library uses
-(extern const versus function) depends on what functionality the library
-might wish to declare. The <code>extern const</code> model uses the smallest code
-footprint, but since its constant cannot be changed at runtime (based on
-the configuration of the device say). The <code>extern function</code> call requires
-the BSP to implement a function which allows flexibility to assign the
-GPIO for the light switch to be determined at runtime with a small expense of
-slightly more code.</p>
-<p>Then the <code>libs/light</code> would go on to use the specified GPIO during its runtime
-execution. For example this shows both ways the library could interface to the
-bsp to get the right GPIO:</p>
-<div class="codehilite" style="background: #ffffff"><pre style="line-height: 125%"> void light_on(void) {
- . . .
- /* finally time to turn the light on */
- hal_gpio_set(light_switch_gpio);
- }
-
- void light_on(void) {
- . . .
- int pin = bsp_light_app_get_light_gpio();
- /* finally time to turn the light on */
- hal_gpio_set(pin);
- }
-</pre></div>
-
-
-<p>When you library user includes <code>libs/light</code> as a dependency and then builds
-with <strong>newt</strong>, they will get an unresolved external for either <code>light_switch_gpio</code>
-or <code>bsp_light_app_get_light_gpio()</code> and will need to add to their BSP.</p>
-<p>In their BSP, they can add </p>
-<div class="codehilite" style="background: #ffffff"><pre style="line-height: 125%"> const int light_switch_gpio = 5;
-</pre></div>
-
-
-<p>or</p>
-<div class="codehilite" style="background: #ffffff"><pre style="line-height: 125%"> int bsp_light_app_get_light_gpio(void) {
- return my_configured_lightswitch_io();
- }
-</pre></div>
-
-
-<p>So where did the number <code>5</code> come from. Their BSP already includes the specific
-MCU that they are using. And their <code>mcu/xxx/hal_gpio.c</code> already defines
-the mapping between physical pins and the virtual device ids. </p>
-<p>The user can determine (when writing code) from their boards physical pinmap
-and from the <code>hal_gpio.c</code> MCU mapping which virtual device_id corresponds
-to the correct physical pin in their system.</p>

-<p>The hardware independent interface to Pulse Width Modulators</p>
-<h3 id="description">Description</h3>
-<p>Pulse Width Modulators (PWMs) are hardware devices that output digital waveforms
-with programmable duty cycle and frequency. They use a digital waveform
-but can contiuously adjust the amount of power delivered to their load via
-duty cycle. They are often used to create analog waveforms via low pass filter,
-drive LEDs at various intensities, and control DC or servo motors.</p>
-<p>For a description of PSM, see <a href="https://en.wikipedia.org/wiki/Pulse-width_modulation">wikipedia</a></p>
-<h3 id="definition">Definition</h3>
-<p><a href="https://github.com/apache/incubator-mynewt-larva/blob/master/hw/hal/include/hal/hal_pwm.h">hal_pwm.h</a></p>
-<h3 id="hal_pwm-theory-of-operation">HAL_PWM Theory Of Operation</h3>
-<p>The HAL_PWM interface was designed with some specific use cases in mind. It
-was also designed to exploit a subset of the functionality provided by
-common PWM controllers.</p>
-<p>Fundamentally, a PWM has at it root an N-bit COUNTER, a CLOCK source, one or
-more CAPTURE registers, and sometimes a TOP register.</p>
-<p>The clock source feeds the COUNTER register which is continuously counting
-(up or down), When the COUNTER is less than the value of the CAPTURE
-register, the PWM outputs a logic HIGH. When the counter is greater than
-the CAPTURE register the PWM outputs logic LOW. When the counter reaches the TOP
-register, it wraps back to zero. If the PWM has no TOP register, it simply
-wraps back to zero after reaching 2^N-1.</p>
-<p>The HAL_PWM abstracts this implementation and provides methods to set the
-PWM frequency and duty cycle. The frequency is the rate at which the counter
-wraps back to zero. The duty cycle is the fraction of time the PWM is in
-logic HIGH state.</p>
-<p>The HAL_PWM API provides a few methods to get information on the PWM.</p>
-<table>
-<thead>
-<tr>
-<th><strong>Method Name</strong></th>
-<th><strong> Description </strong></th>
-</tr>
-</thead>
-<tbody>
-<tr>
-<td>hal_pwm_get_source_clock_freq</td>
-<td>gets the frequency of the CLOCK that is driving the COUNTER</td>
-</tr>
-<tr>
-<td>hal_pwm_get_resolution_bits</td>
-<td>gets the number of bits in the COUNTER</td>
-</tr>
-</tbody>
-</table>
-<p>To use a PWM via HAL_PWM, follow these simple steps.</p>
-<p>1) initialize a PWM using <code>hal_pwm_init</code> -- this binds the driver to the device
-for the specific PWM you are using
-2) Optionally set the frequency of the PWM using <code>hal_pwm_set_frequency</code>
--- PWMs that support a TOP register have fine control over their frequency
-settings. If this command is not supported by the PWM it will return an error
-and its likely that there is no TOP register; the frequency resolution is not
-finely adjustable. See the BSP for coarse adjustment of the PWM frequency.<br />
-3) Enable the PWM to output a specific duty cycle using the
-<code>hal_pwm_enable_duty_cycle</code> API</p>
-<p>To change the duty cycle dynamically, just issue another
-<code>hal_pwm_enable_duty_cycle</code> command.</p>
-<p>To disable the PWM waveform, use <code>hal_pwm_disable</code>.</p>

<p>SPI is called a 4-wire interface because of the 4 signals, MISO, MOSI, CLK,
and SS. The SS signal (slave select) is an active low signal that activates
a SPI slave device. This is how a master "addresses" a particular slave
device. Often this signal is also referred to as "chip select" as it
selects particular slave device for communications.</p>

+<p>The Mynewt SPI HAL has blocking and non-blocking transfers. Blocking means that the API call
to transfer a byte will wait until the byte completes transmissions before
-the function returns.</p>
-<p>Since SPI is generally a shared communications bus, the hal_spi API allows
-SPI runtime configuration to be compatible with the data format and speed of the
-slave device. See the <code>hal_spi_config</code> method in the API above for a
-description of the available settings. These settings are critical to the
-operation of the slave device.</p>
-<p>The Mynewt SPI HAL does not include built-in SS signaling. Its up to the
-hal_spi user to control their own SS pins. Typically applications will do
-this with GPIO.</p>
-<p>An example of this would look like this (error handling excluded for brevity):</p>
-<div class="codehilite" style="background: #ffffff"><pre style="line-height: 125%"> /* each device may have different settings */
- extern struct hal_spi_settings dev1;

- gpio_init_out(SS_DEV_2, 1);
- hal_spi *pspi = hal_spi_init(SPI0);
-

- /* write a single byte (0) to device 1 */
- hal_spi_config(pspi, &dev1);

+the function returns. Blocking interface can be used for only the master slave SPI type.
+Non-blocking means he function returns control to the execution environment immediately after the API call and a callback function is executed at the completion of the transmission. Non-blocking interface can be used for both master and slave SPI types.</p>
+<p>The <code>hal_spi_config</code> method in the API above allows the SPI to be configured with appropriate settings for master or slave. It Must be called after the spi is initialized (i.e. after hal_spi_init is called) and when the spi is disabled (i.e. user must call hal_spi_disable if the spi has been enabled through hal_spi_enable prior to calling this function). It can also be used to reconfigure an initialized SPI (assuming it is disabled as described previously).</p>

Future\nversion will support SPI slave functionality.\n\n\nDefinition\n\n\nhal_spi.h\n\n\nHAL_SPI Theory Of Operation\n\n\nSPI is called a 4-wire interface because of the 4 signals, MISO, MOSI, CLK, \nand SS. The SS signal (slave select) is an active low signal that activates\na SPI slave device. This is how a master \"addresses\" a particular slave\ndevice. Often this signal is also referred to as \"chip select\" as it\nselects particular slave device for communications.\n\n\nThe Mynewt SPI HAL has blocking transfers. This means that the API call\nto transfer a byte will wait until the byte completes transmissions before\nthe function returns.\n\n\nSince SPI is gene
rally a shared communications bus, the hal_spi API allows\nSPI runtime configuration to be compatible with the data format and speed of the \nslave device. See the \nhal_spi_config\n method in the API above for a \ndescription of the available settings.

transmissions before\nthe function returns.

- MyNewt is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.

+ MyNewt is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.

-<p>The CPU time is not the same as the <a href="">os_time</a>. Typically,
-the os_time is set to a much slower tick rate than the CPU time. The CPU
-time should be used for timing real-time events at exact times. The os_time
-should be used for system level timeout etc that are not in fine time
-resolutions. In fact, cputime is not part of the os at all, but a hardware
-layer abstraction to high resolution timers.</p>
-<p>There are methods to get the cputime as 32-bit and 64-bit values. Both
-values may eventually wrap, but for timing short events a 32-bit value
-may be sufficient and would</p>

- MyNewt is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.

<p>The device_id (in this case called <code>pin</code>) is not a physical device
(actual hardware pin), but a virtual pin which is defined by the
-implementation of the HAL (and documented in the implementation of the HAL)</p>
-<p>Below this, there are two different paradigms for HAL interface. They are
-discussed below.</p>
-<h2 id="direct-hal-interface">Direct HAL Interface</h2>
-<p>In one HAL paradigm called <strong>direct HAL</strong>, the header file is the only component
-of the HAL interface. Implementers of this HAL would create a source file
-that implements these methods. </p>
-<p>This has the advantage of being simple, small, and low execution overhead.</p>
-<p>It has the disadvantage that its not possible to have two different implementations
-of the same <strong>direct HAL</strong> within the same image. Said another way, if I create
-a <strong>direct HAL</strong> <code>hal_foo.h</code>, there can be many implementations of
-<code>xxx/hal_foo.c</code> but only one can be included in a project. </p>
-<p>For example, support there is an ADC attached directly to the MCU and an ADC
-that is attached via SPI. There would be no way in this simple paradigm
-to use both these devices from the HAL API at the same time.</p>
-<p>Current Direct HAL interfaces include:</p>

-<p>This brings up the second paradigm.</p>
-<h2 id="indirect-hal-interface">Indirect HAL Interface</h2>
-<p>The second paradigm, <strong>indirect HAL</strong> preserves the simple function
-API with enumerated device_id but adds a small layer of code in the
-HAL to allow different implementations to connect at runtime.</p>
-<p>The abstract interface contains three components:</p>
-<ul>
-<li>A header file <code>hal_foo.h</code> that includes the API above with a <code>device_id</code></li>
-<li>An implementation <code>hal/hal_foo.c</code> which maps the <code>device_id</code> to
-a driver interface structure. </li>
-<li>A driver interface structure that is defined for the underlying implementation</li>
-</ul>
-<p>Using this simple model, the user can be exposed to a simple function
-interface (without structures or function pointers) and the system can provide
-a different software implementation for each device id.</p>
-<p>Although the GPIO interface for Mynewt uses the <strong>direct HAL</strong>, we can describe
-what it might look like for an indirect HAL. </p>
-<p>The API <code>hal_gpio.h</code> is identical with a direct or indirect HAL.</p>
-<p>In the indirect HAL there is an additional header file <code>hal_gpio_int.h</code>
- which describes the driver interface for underlying implementations. It
-looks similar to the HAL API except is driven by function pointers.</p>
-<div class="codehilite" style="background: #ffffff"><pre style="line-height: 125%">struct hal_gpio_funcs {
- void (*hgpio_set)(void);
- . . .
-};
-
-struct hal_gpio_int {
- struct hal_gpio_funcs funcs;
-}
-
-const struct hal_gpio_int *bsp_gpio_dev(uint8_t pin);
-</pre></div>
-
-
-<p>The BSP specific function is what will map the specific pin (device_id)
-to its implementation.</p>
-<p>This is different than the <strong>direct HAL</strong> which maps this virtual/physical
-device pairing in the MCU implementation. For the <strong>indirect HAL</strong> the
-mapping has to be done in the BSP since that is the place where multiple
-disparate devices can be enumerated into a single <code>device_id</code> space.</p>
-<p>An interface file <code>hal/hal_gpio.c</code> would perform the mapping as
-follows:</p>
-<div class="codehilite" style="background: #ffffff"><pre style="line-height: 125%"> void hal_gpio_set(int pin) {
- const struct hal_gpio_int *pgpio;
- pgpio = bsp_get_gpio_device(pin);
- if(pgpio) {
- pgpio->funcs.set();
- }
- }
-</pre></div>
-
-
-<p>The implementer of GPIO functionality (say in <code>mcu/xxx/hal_gpio.c</code>) would
-implement the structure and provide the function pointers.</p>
-<div class="codehilite" style="background: #ffffff"><pre style="line-height: 125%">void xxx_hal_gpio_set(void) {
- /* implementation for this particular gpio device */
- . . .
-}
-
-struct hal_gpio_int xxx_hal_gpio = {
- .funcs.hgpio_set = xxx_hal_gpio_set;
-}
-</pre></div>
-
-
-<p>This leaves the BSP implementation to complete the function </p>
-<div class="codehilite" style="background: #ffffff"><pre style="line-height: 125%">const struct hal_gpio_int *bsp_gpio_dev(uint8_t pin) {
- switch(pin) {
- case 0:
- return &xxx_hal_gpio;
- case 1:
- return &yyy_hal_gpio;
- }
- return NULL;
-}
-</pre></div>
-
-
-<p><strong>NOTE</strong>: In this example there could be 10s of GPIO. It may be memory inefficient
-to have that many <code>hal_gpio_int</code> structures around to basically call the
-same functions. In Mynewt today, the hal_gpio is a <strong>direct HAL</strong> and does
-not have this overhead. More HAL paradigms may be added in the future to address
-the flexibility of the <strong>indirect HAL</strong> with the memory efficiency of the <strong>direct HAL</strong></p>

-<p>Future HAL_DAC APIs will include A DMA interface to automatically write

-<p>The Mynewt HAL also supports a <a href="../../hal_pwm/hal_pwm/">PWM</a> interface which can
-be used in conjunction with a low pass filter to set an analog output voltage.</p>

- MyNewt is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.

- MyNewt is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.

<p>The device_id (in this case called <code>pin</code>) is not a physical device
(actual hardware pin), but a virtual pin which is defined by the
-implementation of the HAL (and documented in the implementation of the HAL)</p>
-<p>Below this, there are two different paradigms for HAL interface. They are
-discussed below.</p>
-<h2 id="direct-hal-interface">Direct HAL Interface</h2>
-<p>In one HAL paradigm called <strong>direct HAL</strong>, the header file is the only component
-of the HAL interface. Implementers of this HAL would create a source file
-that implements these methods. </p>
-<p>This has the advantage of being simple, small, and low execution overhead.</p>
-<p>It has the disadvantage that its not possible to have two different implementations
-of the same <strong>direct HAL</strong> within the same image. Said another way, if I create
-a <strong>direct HAL</strong> <code>hal_foo.h</code>, there can be many implementations of
-<code>xxx/hal_foo.c</code> but only one can be included in a project. </p>
-<p>For example, support there is an ADC attached directly to the MCU and an ADC
-that is attached via SPI. There would be no way in this simple paradigm
-to use both these devices from the HAL API at the same time.</p>
-<p>Current Direct HAL interfaces include:</p>

-<p>This brings up the second paradigm.</p>
-<h2 id="indirect-hal-interface">Indirect HAL Interface</h2>
-<p>The second paradigm, <strong>indirect HAL</strong> preserves the simple function
-API with enumerated device_id but adds a small layer of code in the
-HAL to allow different implementations to connect at runtime.</p>
-<p>The abstract interface contains three components:</p>
-<ul>
-<li>A header file <code>hal_foo.h</code> that includes the API above with a <code>device_id</code></li>
-<li>An implementation <code>hal/hal_foo.c</code> which maps the <code>device_id</code> to
-a driver interface structure. </li>
-<li>A driver interface structure that is defined for the underlying implementation</li>
-</ul>
-<p>Using this simple model, the user can be exposed to a simple function
-interface (without structures or function pointers) and the system can provide
-a different software implementation for each device id.</p>
-<p>Although the GPIO interface for Mynewt uses the <strong>direct HAL</strong>, we can describe
-what it might look like for an indirect HAL. </p>
-<p>The API <code>hal_gpio.h</code> is identical with a direct or indirect HAL.</p>
-<p>In the indirect HAL there is an additional header file <code>hal_gpio_int.h</code>
- which describes the driver interface for underlying implementations. It
-looks similar to the HAL API except is driven by function pointers.</p>
-<div class="codehilite" style="background: #ffffff"><pre style="line-height: 125%">struct hal_gpio_funcs {
- void (*hgpio_set)(void);
- . . .
-};
-
-struct hal_gpio_int {
- struct hal_gpio_funcs funcs;
-}
-
-const struct hal_gpio_int *bsp_gpio_dev(uint8_t pin);
-</pre></div>
-
-
-<p>The BSP specific function is what will map the specific pin (device_id)
-to its implementation.</p>
-<p>This is different than the <strong>direct HAL</strong> which maps this virtual/physical
-device pairing in the MCU implementation. For the <strong>indirect HAL</strong> the
-mapping has to be done in the BSP since that is the place where multiple
-disparate devices can be enumerated into a single <code>device_id</code> space.</p>
-<p>An interface file <code>hal/hal_gpio.c</code> would perform the mapping as
-follows:</p>
-<div class="codehilite" style="background: #ffffff"><pre style="line-height: 125%"> void hal_gpio_set(int pin) {
- const struct hal_gpio_int *pgpio;
- pgpio = bsp_get_gpio_device(pin);
- if(pgpio) {
- pgpio->funcs.set();
- }
- }
-</pre></div>
-
-
-<p>The implementer of GPIO functionality (say in <code>mcu/xxx/hal_gpio.c</code>) would
-implement the structure and provide the function pointers.</p>
-<div class="codehilite" style="background: #ffffff"><pre style="line-height: 125%">void xxx_hal_gpio_set(void) {
- /* implementation for this particular gpio device */
- . . .
-}
-
-struct hal_gpio_int xxx_hal_gpio = {
- .funcs.hgpio_set = xxx_hal_gpio_set;
-}
-</pre></div>
-
-
-<p>This leaves the BSP implementation to complete the function </p>
-<div class="codehilite" style="background: #ffffff"><pre style="line-height: 125%">const struct hal_gpio_int *bsp_gpio_dev(uint8_t pin) {
- switch(pin) {
- case 0:
- return &xxx_hal_gpio;
- case 1:
- return &yyy_hal_gpio;
- }
- return NULL;
-}
-</pre></div>
-
-
-<p><strong>NOTE</strong>: In this example there could be 10s of GPIO. It may be memory inefficient
-to have that many <code>hal_gpio_int</code> structures around to basically call the
-same functions. In Mynewt today, the hal_gpio is a <strong>direct HAL</strong> and does
-not have this overhead. More HAL paradigms may be added in the future to address
-the flexibility of the <strong>indirect HAL</strong> with the memory efficiency of the <strong>direct HAL</strong></p>

Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.

<h1 id="using-hal-in-your-libraries">Using HAL in Your Libraries</h1>
<p>This page describes the recommended way to implement libraries that
utilize HAL functionality.</p>
-<p>Consider the light switch example from the <a href="../hal/">HAL overview</a> page.</p>
-<p>The light switch module needs a GPIO pin to set
-the light switch to on or off. The module declares that the GPIO to
-control the light switch is declared elsewhere in one of two methods.</p>
-<div class="codehilite" style="background: #ffffff"><pre style="line-height: 125%"> extern const int light_switch_gpio;
-</pre></div>
-
-
-<p>or</p>
-<div class="codehilite" style="background: #ffffff"><pre style="line-height: 125%"> extern int bsp_light_app_get_light_gpio();
-</pre></div>
-
-
-<p>Which method a library uses
-(extern const versus function) depends on what functionality the library
-might wish to declare. The <code>extern const</code> model uses the smallest code
-footprint, but since its constant cannot be changed at runtime (based on
-the configuration of the device say). The <code>extern function</code> call requires
-the BSP to implement a function which allows flexibility to assign the
-GPIO for the light switch to be determined at runtime with a small expense of
-slightly more code.</p>
-<p>Then the <code>libs/light</code> would go on to use the specified GPIO during its runtime
-execution. For example this shows both ways the library could interface to the
-bsp to get the right GPIO:</p>
-<div class="codehilite" style="background: #ffffff"><pre style="line-height: 125%"> void light_on(void) {
- . . .
- /* finally time to turn the light on */
- hal_gpio_set(light_switch_gpio);
- }
-
- void light_on(void) {
- . . .
- int pin = bsp_light_app_get_light_gpio();
- /* finally time to turn the light on */
- hal_gpio_set(pin);
- }
-</pre></div>
-
-
-<p>When you library user includes <code>libs/light</code> as a dependency and then builds
-with <strong>newt</strong>, they will get an unresolved external for either <code>light_switch_gpio</code>
-or <code>bsp_light_app_get_light_gpio()</code> and will need to add to their BSP.</p>
-<p>In their BSP, they can add </p>
-<div class="codehilite" style="background: #ffffff"><pre style="line-height: 125%"> const int light_switch_gpio = 5;
-</pre></div>
-
-
-<p>or</p>
-<div class="codehilite" style="background: #ffffff"><pre style="line-height: 125%"> int bsp_light_app_get_light_gpio(void) {
- return my_configured_lightswitch_io();
- }
-</pre></div>
-
-
-<p>So where did the number <code>5</code> come from. Their BSP already includes the specific
-MCU that they are using. And their <code>mcu/xxx/hal_gpio.c</code> already defines
-the mapping between physical pins and the virtual device ids. </p>
-<p>The user can determine (when writing code) from their boards physical pinmap
-and from the <code>hal_gpio.c</code> MCU mapping which virtual device_id corresponds
-to the correct physical pin in their system.</p>

+ MyNewt is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.

-<p>The hardware independent interface to Pulse Width Modulators</p>
-<h3 id="description">Description</h3>
-<p>Pulse Width Modulators (PWMs) are hardware devices that output digital waveforms
-with programmable duty cycle and frequency. They use a digital waveform
-but can contiuously adjust the amount of power delivered to their load via
-duty cycle. They are often used to create analog waveforms via low pass filter,
-drive LEDs at various intensities, and control DC or servo motors.</p>
-<p>For a description of PSM, see <a href="https://en.wikipedia.org/wiki/Pulse-width_modulation">wikipedia</a></p>
-<h3 id="definition">Definition</h3>
-<p><a href="https://github.com/apache/incubator-mynewt-larva/blob/master/hw/hal/include/hal/hal_pwm.h">hal_pwm.h</a></p>
-<h3 id="hal_pwm-theory-of-operation">HAL_PWM Theory Of Operation</h3>
-<p>The HAL_PWM interface was designed with some specific use cases in mind. It
-was also designed to exploit a subset of the functionality provided by
-common PWM controllers.</p>
-<p>Fundamentally, a PWM has at it root an N-bit COUNTER, a CLOCK source, one or
-more CAPTURE registers, and sometimes a TOP register.</p>
-<p>The clock source feeds the COUNTER register which is continuously counting
-(up or down), When the COUNTER is less than the value of the CAPTURE
-register, the PWM outputs a logic HIGH. When the counter is greater than
-the CAPTURE register the PWM outputs logic LOW. When the counter reaches the TOP
-register, it wraps back to zero. If the PWM has no TOP register, it simply
-wraps back to zero after reaching 2^N-1.</p>
-<p>The HAL_PWM abstracts this implementation and provides methods to set the
-PWM frequency and duty cycle. The frequency is the rate at which the counter
-wraps back to zero. The duty cycle is the fraction of time the PWM is in
-logic HIGH state.</p>
-<p>The HAL_PWM API provides a few methods to get information on the PWM.</p>

-<p>To use a PWM via HAL_PWM, follow these simple steps.</p>
-<p>1) initialize a PWM using <code>hal_pwm_init</code> -- this binds the driver to the device
-for the specific PWM you are using
-2) Optionally set the frequency of the PWM using <code>hal_pwm_set_frequency</code>
--- PWMs that support a TOP register have fine control over their frequency
-settings. If this command is not supported by the PWM it will return an error
-and its likely that there is no TOP register; the frequency resolution is not
-finely adjustable. See the BSP for coarse adjustment of the PWM frequency.<br />
-3) Enable the PWM to output a specific duty cycle using the
-<code>hal_pwm_enable_duty_cycle</code> API</p>
-<p>To change the duty cycle dynamically, just issue another
-<code>hal_pwm_enable_duty_cycle</code> command.</p>
-<p>To disable the PWM waveform, use <code>hal_pwm_disable</code>.</p>

- MyNewt is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.

<p>SPI is called a 4-wire interface because of the 4 signals, MISO, MOSI, CLK,
and SS. The SS signal (slave select) is an active low signal that activates
a SPI slave device. This is how a master "addresses" a particular slave
device. Often this signal is also referred to as "chip select" as it
selects particular slave device for communications.</p>

+<p>The Mynewt SPI HAL has blocking and non-blocking transfers. Blocking means that the API call
to transfer a byte will wait until the byte completes transmissions before
-the function returns.</p>
-<p>Since SPI is generally a shared communications bus, the hal_spi API allows
-SPI runtime configuration to be compatible with the data format and speed of the
-slave device. See the <code>hal_spi_config</code> method in the API above for a
-description of the available settings. These settings are critical to the
-operation of the slave device.</p>
-<p>The Mynewt SPI HAL does not include built-in SS signaling. Its up to the
-hal_spi user to control their own SS pins. Typically applications will do
-this with GPIO.</p>
-<p>An example of this would look like this (error handling excluded for brevity):</p>
-<div class="codehilite" style="background: #ffffff"><pre style="line-height: 125%"> /* each device may have different settings */
- extern struct hal_spi_settings dev1;
- extern struct hal_spi_settings dev2;

- gpio_init_out(SS_DEV_1, 1);
- gpio_init_out(SS_DEV_2, 1);
- hal_spi *pspi = hal_spi_init(SPI0);
-
- ...
- /* write a single byte (0) to device 1 */
- hal_spi_config(pspi, &dev1);
- gpio_clear(SS_DEV_1)
- rc = hal_spi_transfer(pspi, 0)
- gpio_set(SS_DEV_1)
-
- /* read a single byte from device 2 */

+the function returns. Blocking interface can be used for only the master slave SPI type.
+Non-blocking means he function returns control to the execution environment immediately after the API call and a callback function is executed at the completion of the transmission. Non-blocking interface can be used for both master and slave SPI types.</p>
+<p>The <code>hal_spi_config</code> method in the API above allows the SPI to be configured with appropriate settings for master or slave. It Must be called after the spi is initialized (i.e. after hal_spi_init is called) and when the spi is disabled (i.e. user must call hal_spi_disable if the spi has been enabled through hal_spi_enable prior to calling this function). It can also be used to reconfigure an initialized SPI (assuming it is disabled as described previously).</p>
