[GitHub] [incubator-nuttx] michallenc opened a new pull request #4231: adc: add ioctl command to get the number of configured channels

[GitBox <gi...@apache.org>]

michallenc opened a new pull request #4231:
URL: https://github.com/apache/incubator-nuttx/pull/4231


   ## Summary
   Number of configured ADC channels is currently only defined in board
   level section, typically in xxx_adc.c file. This commit introduces
   ioctl command ANIOC_GET_NCHANNELS that returns the number of configured
   channels which is determined by the driver code. The change can allow the
   applications to be more flexible when it comes to multiple ADC devices
   with different number of configured channels.
   
   The problem was already mentioned in an issue #4217.
   
   ## Impact
   None on current functionality, just adds additional option to get the number of channels to all current ADC drivers.
   
   ## Testing
   Tested with pysimCoder application on iMXRT and STM32 boards.
