Probably you will have to disable some other functions. Also you have to usnerstand what the board is designed like - some ports have specific and reserved functions. Finally, there are such things like wrong baud rate on a serial port which may make you think it's not working while you are just using bad user mode settings. > Is it possible to reconfigure all PSC's as UART's ? Yes, it is. But you have to know what you are doing.
