[Purpose] The Fang·Xingguang development board and the DWIN serial port screen are realized through serial port communication. First of all, the serial port debugging must be passed.

1. Connect to the serial port:

2. The serial port of the development board is ttyS0, and the file is located at /dev/ttyS0. First, you need to obtain read and write permissions, otherwise an error will occur when opening the device:

sudo chmod -R 777 /dev/ttyUSB0

3. Enter python:

>>> import serial
>>> ser = serial.Serial("/dev/ttyS0",115200,timeout=0.5)
>>> str_data = "hello world\r\n"
>>> data_send = str_data.encode("gbk")
>>> ser.write(data_send)
4. Open the serial terminal, and you can receive: hello world:

[Summary] The fedora firmware provided by starfive has already installed python3.9, and many modules have also been installed. So the project should progress quickly. . .
