【[Python原创]】Python控制串口发送指令

代码如下： # !/usr/bin/env python # -*- coding: utf-8 -*- import time import datetime import serial.tools.list_ports def request_500K(): ser = serial.Serial(port="COM_PORT", baudrate=460800, bytesize=serial.EIGHTBITS, stopbits=serial.STOPBITS_ONE,timeout=60) if ser.isOpen(): print("打开串口成功, 串口号: %s" % ser.name) else: print("打开串口失败") # 串口发送数据 data = "AT+QIOPEN=1,0,\"TCP\",ip,port,0,2\r\n\r\n" data1 = "GET /test_500k.txt HTTP/1.1\r\nHost: ip\r\nConnection: close\r\n\r\n" print("发送数据: %s" % data) write_len = ser.write(data.encode('utf-8')) print("等待2S") time.sleep(2) print("发送数据: %s" % data1) write_len1 = ser.write(data1.encode('utf-8')) com_input = ser.read(513000) print(str(com_input)) with open("log.txt", "a") as f: f.write(str(com_input) + "\r\n") # 关闭串口 ser.close() if ser.isOpen(): print("串口未关闭") else: print("串口已关闭") i = 0 while i <= 100: time1 = datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S') time2 = str(time1) print(time2) with open("log.txt", "a") as f: f.write(time2) f.write("\r\n\r\n") request_500K() print("等待5S") time.sleep(5) i += 1
