主要参考Jetson nano串口的使用——UART，有改动

代码

xx.py：

import serial as ser
import time
a = "abcabc\t"
b = 0.
c = "\tfyo"

se = ser.Serial("/dev/ttyTHS1", 9600, timeout=1)

while True:
	b = b + 1
	se.write(a.encode())
	se.write(str(b).encode("GB2312"))
	se.write(c.encode("GB2312"))
	se.write("\r\n".encode())
	print(se.readline().decode("GB2312"))
	time.sleep(1)
	print("send ok")
	print(se.is_open)

运行
