Nucleo F303RE USB Serial Comm HAL example code?

David Pekin · ‎2019-04-17

Hello,

I suspect there's example code for reading and writing serial data through the USB comm port (ST-link cable) on the Nucleo boards using the HAL libraries. Can anyone point me to one?

I've seen the printf() example which is half way there.

Thanks in advance,

Dave

Hello @David Pekin ,

In the Step3 of "STM32 step by step", there is a description of what you need to do to perform serial writing.

It is based on STM32CubeMX, you need just to select the correct board at the beginning.

Thanks. I'll take a look at it. I'll take a look at it. I've already got serial writing to the port via printf() & mapping PUTCHAR to the port. I'm now wanting to make a command prompt handler so I need the reading portion. I'm sure I can reinvent the wheel but thought it must be already around in some example.

Thanks again.
