Hello everyone,i'm encountering a strange issue, I'm trying to read from the ADC on a STM32f429zi.When my pin is grounded the value of the ADC is not 0 but around 1000. When i try to debug the value it doesn't give me any result but says: <optimized ...

I guess you have used the sound meter library? How did you calculate the dB value?

Did you ever managed to get this to work? I'm trying to implement the same library but i have exactly the same error.

So the chip is broken? I have to say i didn't care about ESD. I never had issues with it in the past. And since I2C and SPI are working fine i guess the chip should be alright? So because of the VREFINT ADC readout of 4095 you are sure the chip is br...

Thank you for your feedback.I'm pretty sure it's a hardware issue, my code is working fine.What value pot meter did you use? Please see my reply above since i did a test on VREFINT resulting in a funky value.

I just checked my vrefint with ADC1 and got 4095 as a result. So this means my chip is broken?My input is just a voltage divider with a 10k resistor to ground and the LDR connected to v+. I've tested this with a nucleo and this worked fine so i guess...
