STM32F4: Using several ADCs independent

Hello,

I wonder if it is or it is not possible to use more than one ADC independet of each other. My problem is as follows: I want to use ADC1 and ADC2 in dual mode and ADC3 in independent scan conversion mode. I can successfully ADC1 and ADC2 in dual mode but as soon as I also initialize ADC3 in independent mode, nothing works anymore. My code for ADC3 alone, without using ADC1 and ADC2, also works well. It has to be added, that I use DMA for all ADCs. I don't see whre the problem is... #independend #adc #stm32f4

Common initialization must only be done once. Dual mode infers third unit is independent.
