I have made a target board using STM32G484VE . I am using 11 ADC pins spread across ADC1 - ADC5. I have introduced a 3.3V Zener BZT52-B3V3 as a protection at all ADC inputs, but all the ADC voltages read 0.6V less from the actual voltage ? Any reason...
I have designed a target board based on STM32G484VE and I am encountering a problem with GPIO outputs while powering on.The requirement is no output should get high status while powering on or during reset. So I have configured the IOs using CUBEMX ...
