- * @brief This file provides firmware functions to manage the following
- * functionalities of the Digital-to-Analog Converter (DAC) peripheral:
- * + DAC channels configuration: trigger, output buffer, data format
- * + DMA management
- * + Interrupts and flags management
- *
- @verbatim
-
- ===============================================================================
- ##### DAC Peripheral features #####
- ===============================================================================
- [..] The device integrates two 12-bit Digital Analog Converters that can
- be used independently or simultaneously (dual mode):
- (#) DAC1 integrates two DAC channels:
- (++) DAC1 channel 1 with DAC1_OUT1 as output
- (++) DAC1 channel 2 with DAC1_OUT2 as output
- (++) The two channels can be used independently or simultaneously (dual mode)
-
- (#) DAC2 integrates only one channel DAC2 channel 1 with DAC2_OUT1 as output
-
- [..] Digital to Analog conversion can be non-triggered using DAC_Trigger_None
- and DAC_OUT1/DAC_OUT2 is available once writing to DHRx register using
- DAC_SetChannel1Data()/DAC_SetChannel2Data.
-
- [..] Digital to Analog conversion can be triggered by:
- (#) External event: EXTI Line 9 (any GPIOx_Pin9) using DAC_Trigger_Ext_IT9.
- The used pin (GPIOx_Pin9) must be configured in input mode.
-
- (#) Timers TRGO: TIM2, TIM8/TIM3, TIM4, TIM6, TIM7, and TIM15
- (DAC_Trigger_T2_TRGO, DAC_Trigger_T4_TRGO...)
- The timer TRGO event should be selected using TIM_SelectOutputTrigger()
- (++) To trigger DAC conversions by TIM3 instead of TIM8 follow
- this sequence:
- (+++) Enable SYSCFG APB clock by calling
- RCC_APB2PeriphClockCmd(RCC_APB2Periph_SYSCFG, ENABLE);
- (+++) Select DAC_Trigger_T3_TRGO when calling DAC_Init()
- (+++) Remap the DAC trigger from TIM8 to TIM3 by calling
- SYSCFG_TriggerRemapConfig(SYSCFG_TriggerRemap_DACTIM3, ENABLE)
- (#) Software using DAC_Trigger_Software
-
- [..] Each DAC channel integrates an output buffer that can be used to
- reduce the output impedance, and to drive external loads directly
- without having to add an external operational amplifier.
- To enable, the output buffer use
- DAC_InitStructure.DAC_OutputBuffer = DAC_OutputBuffer_Enable;
-
- [..] Refer to the device datasheet for more details about output impedance
- value with and without output buffer.
-
- [..] Both DAC channels can be used to generate:
- (+) Noise wave using DAC_WaveGeneration_Noise
- (+) Triangle wave using DAC_WaveGeneration_Triangle
-
- [..] Wave generation can be disabled using DAC_WaveGeneration_None
-
- [..] The DAC data format can be:
- (+) 8-bit right alignment using DAC_Align_8b_R
- (+) 12-bit left alignment using DAC_Align_12b_L
- (+) 12-bit right alignment using DAC_Align_12b_R
-
- [..] The analog output voltage on each DAC channel pin is determined
- by the following equation:
- (+) DAC_OUTx = VREF+ * DOR / 4095 with DOR is the Data Output Register.
- VREF+ is the input voltage reference (refer to the device datasheet)
- e.g. To set DAC_OUT1 to 0.7V, use DAC_SetChannel1Data(DAC_Align_12b_R, 868);
- Assuming that VREF+ = 3.3, DAC_OUT1 = (3.3 * 868) / 4095 = 0.7V
-
- [..] A DMA1 request can be generated when an external trigger (but not
- a software trigger) occurs if DMA1 requests are enabled using
- DAC_DMACmd()
- DMA1 requests are mapped as following:
- (+) DAC channel1 is mapped on DMA1 channel3 which must be already
- configured
- (+) DAC channel2 is mapped on DMA1 channel4 which must be already
- configured
-
- ##### How to use this driver #####
- ===============================================================================
- [..]
- (+) Enable DAC APB1 clock to get write access to DAC registers
- using RCC_APB1PeriphClockCmd(RCC_APB1Periph_DAC, ENABLE)
-
- (+) Configure DACx_OUTy (DAC1_OUT1: PA4, DAC1_OUT2: PA5, DAC2_OUT1: PA6)
- in analog mode.
-
- (+) Configure the DAC channel using DAC_Init()
-
- (+) Enable the DAC channel using DAC_Cmd()

- ===============================================================================
- ##### How to use this driver #####
- ===============================================================================
- [..]
- (#) Enable The DMA controller clock using
- RCC_AHBPeriphClockCmd(RCC_AHBPeriph_DMA1, ENABLE) function for DMA1 or
- using RCC_AHBPeriphClockCmd(RCC_AHBPeriph_DMA2, ENABLE) function for DMA2.
- (#) Enable and configure the peripheral to be connected to the DMA channel
- (except for internal SRAM / FLASH memories: no initialization is necessary).
- (#) For a given Channel, program the Source and Destination addresses,
- the transfer Direction, the Buffer Size, the Peripheral and Memory
- Incrementation mode and Data Size, the Circular or Normal mode,
- the channel transfer Priority and the Memory-to-Memory transfer
- mode (if needed) using the DMA_Init() function.
- (#) Enable the NVIC and the corresponding interrupt(s) using the function
- DMA_ITConfig() if you need to use DMA interrupts.
- (#) Enable the DMA channel using the DMA_Cmd() function.
- (#) Activate the needed channel Request using PPP_DMACmd() function for
- any PPP peripheral except internal SRAM and FLASH (ie. SPI, USART ...)
- The function allowing this operation is provided in each PPP peripheral
- driver (ie. SPI_DMACmd for SPI peripheral).
- (#) Optionally, you can configure the number of data to be transferred
- when the channel is disabled (ie. after each Transfer Complete event
- or when a Transfer Error occurs) using the function DMA_SetCurrDataCounter().
- And you can get the number of remaining data to be transferred using
- the function DMA_GetCurrDataCounter() at run time (when the DMA channel is
- enabled and running).
- (#) To control DMA events you can use one of the following two methods:
- (##) Check on DMA channel flags using the function DMA_GetFlagStatus().
- (##) Use DMA interrupts through the function DMA_ITConfig() at initialization
- phase and DMA_GetITStatus() function into interrupt routines in
- communication phase.
- After checking on a flag you should clear it using DMA_ClearFlag()
- function. And after checking on an interrupt event you should
- clear it using DMA_ClearITPendingBit() function.
