B96b-f446ve usbtx & usbrx pins

Mbed OS

I want to use B96B-F446VE or the device STM32F446VET6. I would like to know which are the default USBRX (SERIAL_RX) and USBTX (SERIAL_TX) pins.

You can find that info in PinNames.h.

Looks like TX is PC_10 and RX is PC_11 .

That’s the else condition. What is “MBED_CONF_TARGET_STDIO_UART_TX” if “MBED_CONF_TARGET_STDIO_UART_TX=TRUE”?

I think MBED_CONF_TARGET_STDIO_UART_TX is false unless you define it. So, the app uses the default pin. See the "config": section in the link below.

You can override the default configuration with mbed_app.json file.

Many thanks for the prompt and clear answer.
