Posted on December 13, 2016 at 19:27I am trying to implement such an algorithm on Stm32f4-discovery: Initialize the DMA and Tripple-ADC in the interleaved mode on the same channelWait for an external interruptSuspend the DMA and ADCsSend the buffer...

Posted on December 14, 2016 at 16:54Thank you very much! I've checked the ADC flags and saw that the ADC overrun error was occurring. So, I added an interrupt to handle it and now the problem is solved completely.

Posted on December 13, 2016 at 20:38Nope, I am sure that it is stuck. ADCs dont't write anything in the buffer until next interrupt, as I am filling the buffer with the 0xFFFFFFFFs during the interrupt to test if anything is written to it afterwards...
