I have 6 channels on ADC1 and 2 channels on ADC2. I need the first two channels of ADC1 to be sampled simultaneously with the two channels of ADC2. The sampling needs to be triggered by a timer and occur twice each time the timer triggers.
Here’s what I did: I set the ADC mode to dual regular simultaneous + alternate trigger mode and enabled DMA access mode. I enabled continuous DMA requests and set the DMA to normal mode (not circular), so the buffer is filled only once each time the timer triggers. I also set the buffer size to 16, so the ADC channels are sampled twice and then stop once the buffer is filled. After that, the system waits for the next timer trigger.
Am I missing something?
