Using multiple ADC-s with DMA simultaneously – STM32
Is there a way to use DMA with multiple ADCs at the same time?
I know you can scan multiple channels on one ADC, but I currently use 5 different ADCs on my STM32G4.
I use the HAL library function <...

STM32L476 Discovery ADC output is not changing even though the input voltage is
The output value of the ADC seems to flicker between 539-549 (in a range of 0-4095) no matter what voltage is on the input pin. The voltage on the input is usually between 0V - 4V. This might be a ...

STM32F4 ADC oscillating
I am trying to read the ADC of a STM32F4. The code skeleton was generated by CubeMX, the HAL library is used. The read values are feasible but have periodic noise, as seen here:
The plot was ...

STM32 ADC conversion using HAL
I am trying to learn how to use "new" HAL library from stm32.
When I try to do simple ADC conversion it works just one time, but then it stops converting. I suppose End of conversion flag does not get ...
