This example is based on the GD32W515P-EVAL-V1.0 board, it shows how to use the USART
to detect and automatically set the USARTx_BAUD value based on the reception of
one character.
In this demo, firstly, the USART sends "\n\rUSART auto baudrate detection example\n\r"
to the hyperterminal, USART_ABDM_FTOF is set as the auto baud rate detection mode. If auto
baud rate detection is completed without error, LED1 is on.
You can send any character be in a start 10xxxxxx frame format(eg.0x05 or 0x01)
to implement the auto baud rate detection.
