Hi,

thank you for making the DAC+ ADC!

Could you please tell me what is the best way to read the ADC sample data in linux (e.g., via the filesystem or an API, preferably in C)?

Thank you!

Best regards,
Andreas

  Hi Andreas,

  the DAC+ ADC can be access via the ALSA API:

  Hi,
  I'm working on being as efficient as possible collecting samples from ADC.
  Could you precise the buffer size on DAC+ADC board, please ?
  
  Thank you

  There is no buffer on the board. Buffering only happens on the Pi.
