关于python:python串口自动测试

装置应用 pip install pyserial

关上和退出信号

com = serial.Serial("com15", 115200, timeout=0.5)def sig_handler(sig, frame):    com.close()    exit(0)signal.signal(signal.SIGTERM, sig_handler)signal.signal(signal.SIGINT, sig_handler)try:    com.open()except:    com.close()    com.open()

读取一行输入

    try:        readline = str(com.readline(), encoding = "utf8")    except:        continue

读取指定信息时候发送指定命令

    try:        if re.findall(r'xxx readline, flags=0):            com.write(bytes("\r\nreboot\r\n", encoding = "utf8"))    except:        print("some errr....")
