Hi,We have a custom board with a STM32G071R8T6TR, PA4 is configured as input but it does not work.All other inputs on the boards are working correct but PA4 is a problem.If we configure PA4 as an output it works fine, we toggle hi/lo, we have checked...

Hi Jan,We went back to basics and we are running from a very basic program using no other features. :)Yes the pins work at 3.3V.MPF

Hi JAn,Yes this is correct.So when PA4 is configured to output and is set to 0 we read IDR as 0 - this is ok.When we set PA4 to 1 we still read IDR as 0 even though we see 1 on the oscilloscope. If we do the above on other pins like PA5 and PA6 this...
