Hello,
Currently i've a problem using DMA with ADC.
My use case is: i've 6 ADC Channels, I am triggering adc with a sampling rate and after number of samples requested i want to get all samples in a one go or even after each sample the destination address of each buffer will be incremented internally.
so as an examples, rate is 1 sample per second and number of samples 5, so on first sec, DMA will read from first one then second one till fifth channel and increment each channel destination address by one. next sec it will read from first channel but it'll allocate in the second location of this channel buffer, then second and so on till fifth. and so on.
problem is descriptor never goes to the next one without being exhausted and if i defined number of transactions it will go to second one only after it fills all those transactions.
I successfully used timer to trigger ADC but i couldn't get that done using dma descriptors. i've used single conversion mode and burst mode but both didn't give me this approach.
can you help me with this
