I'm working on STM32F091 MCU fora the first time and I'm trying to test the USART1 on PF0,1. I have just wrote the code and it works well, but now I can't receive the RXNE interrupt.. the tx line works normally.. if I try to set the port as an input I see the correct logic level on pin so the port works, it seems that the shift register of USART NOT WORK. Any idea?
