Posted on November 01, 2017 at 23:01Need to sample 5 channels at 20Hz. Would like an interrupt when the DMA buffer is filled (50 samples). Waiting on boards to arrive and have a few questions:1) Does the ADC or DMA needs restarted after each conve...

Posted on November 02, 2017 at 18:15Thank you for your perspective. Shortcuts without rigorous testing often lead to long cuts (as I have experienced with ST's sensor APIs). I'll keep this in mind as I gain experience to try to move toward elimina...

Posted on November 02, 2017 at 14:26Clive, thank you for the quick response. I intend to use a 50 sample circular buffer, read between the 20Hz triggers.Question 2: If I want the ADC to trigger on a timer and use DMA, then both of these functions n...
