Hello community , Am using STM32H745ZIT6 MCU in that  configured ADC (4 channnels)  triggered by timer and data collected in DMA .ADC is tiggered by timer (all the 4 channels at a time ) . I want to trigger each channels seperately(in a single ADC) by using different timer or timer channels and collect the data in DMA  this case is possible to do .???   If Yes? any Suggestion . if NO ? Why ?

    Hello,

    From architectural point of view it's not possible to trigger different channels of the same ADC with different timers. Because you can only select one event at a time:
