Send and receive single bytes through uart via com port

[arduo]

Hi i want to send and receive bytes through uart via com port.

I use the usb device cdc standalone example but that example is not configured for single bytes anyone get an idea how to do this?

Sending and receiving single bytes can be done best with the so called low-level (LL) library. Its source and documentation is provided together with the HAL library. Please see this documentation.

Many users also do direct registers programming, based on the UART documentation in the reference manuals.
