Resolved! I need help with trying to figure out how to set my time using a push button and the RTC peripheral on the STM32G031K8 board. I can't seem to figure out how to get it to increment instead it just keeps getting reset to 00:00:00.

What do I need to do to be able to be able to set the time through the use of a push button. Is there a way to set the hours and min separately or does the RTC need to be set all at once? Here is my call back function where I am trying to set just th...

I have bought a batch of STM32F750N8 MCU's and have found that the following pins do not work. PB14, PB15, and PA12/PA11.

I have tried turning these pins to GPIO's and tried toggling them, however, they seem to just be floating. I can confirm that these pins have been soldered on properly, since I have checked them using an X-RAY inspection system. I can also confirm th...
