7 6 5 UART Serial Rate (bps)
The two modules of mutual communication, the
serial port port rate can be different, the
calibration mode can also be different;
When large data packets are launched
continuously, users need to consider the data
blocking caused by the same port rate, or may
even be lost;
It is generally recommended that the same have
the same the same.
0 0 0 The serial port port rate is 1200
