python - 串口通讯

1. 安装pyserial

pip3 install pyserial

2. 使用方式

config.py

import serial

port = "COM1"
baudrate = 2400
bytesize = serial.SEVENBITS
stopbits = serial.STOPBITS_TWO
parity = serial.PARITY_NONE
timeout = 10

main.py

import serial
import config

ser = serial.Serial(port=config.port,baudrate=config.baudrate,bytesize=config.bytesize, stopbits=config.stopbits, parity=config.parity, timeout=config.timeout)
if ser.isOpen():
    print("打开串口成功")
else:
    print(f'打开串口失败')

while True:
    try:
        data = ser.readline()
        print(data)
    except Exception as e:
        print('接收消息数据出错')
