Hello Together,

I have a problem with my ADC. I tried to search through the Forum but I couldn't find a similar problem.

My plan is to read 6 different Analog Digital Channel on STM32F407 therefore I use ADC1, ADC2 and ADC3. On each of the ADC there are two input Channels. Now I tried to read out the Data in 1Mhz frequency. Therefore I configured my ADCs and my DMA2. The code of my initiation see below.

Now to the description of my Problem, I read out the 6 Channels, but only the first 3 Channels, 1 Channel of each ADC is updated in the Array “ADCConvertedValue[6]” the other 3 Channels would not be read.

 

I am looking forward to read your answers and wish you a nice Weekend

Best Regards

Benjamin
