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