I am planning to upload a ready firmware to this STM32 board. And I need to use it through its USB port(which is also used to upload firmware through its ST-link interface).
Now I know that in Arduino board the USB port and the Tx/Rx pins are one and the same thing. So one can communicate with Arduino through its USB port without doing any modification.
Since I haven't dealt with STM32 in this way, I was wondering how can we figure out whether this has the same functionality. Meaning that can we by default use its USB port to communicate with it? Where in its datasheet or manual we can infer this?
