ADC Result false

Hello

I need to receive the value of multiple Channel of ADC 1

But when my pin 1 is connected to GND i have 1500 of numeric value

Already tested in Arduino and the adc work perfectly

It is a nucleo l432kc without modification

Do you have an Idea

Thanks

Finally y found the solution . The problem was that between two ADC_PollForConversion i was stopping the ADC and that doest work

It is difficult to determine your problem without seeing the code as implemented. Perhaps you are inadvertently converting the temperature channel.

Did you debug step through the code to ensure it is working as expected?

Have you set the ADC input GPIO pins to the correct alternate function?
