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("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")
