Hi together,I have ADC reading issues with my STM32G431. I read the ADC with DMA. The readings are triggered by a burst of pulses (approx. 750 kHz) and the ADC buffer seems to get filled. However, the ADC readings are way to high.A 2.5 voltage regula...

@TDK Thank you for the reply.I found the issue. During the first pulse burst, the voltage was actual over Vref. After the first burst I did not restart the DMA correctly. So the ADC reading got never be updated. Thank you for all the hints

Thank you for the reply!@Community member @TDK The reference voltage is much cleaner than it looks like. The rinning is due to the bad probing.@TDK Yes, VDDA is a bit off. But it does not matter for my application. Yes it is a custom board. VDDA ...
