I have an other issue at the moment. I cant use the GPIOD, VSSI02 is on 3.3V. Im using stm32g0b1kb. It wont toggle it wont read, it does nothing. I have created a small application far away from my main app just to test the GPIO functions.
Hi, I a already Figured it out. But Thank you for the response. I have an other issue at the moment. I cant use the GPIOD, VSSI02 is on 3.3V. Im using stm32g0b1kb. It wont toggle it wont read, it does nothing. What am I missing.
I cant toggle, read or write them? PB9 PB6, and PD1 to PD3
