Python-串口通讯 串口通讯(Serial Communication),是指外设和计算机间,通过数据信号线、地线等,按位进行传输数据的一种通讯方式。 1、前提条件: (1)提供一对收发信息的COM口或者使用虚拟工具创建COM口(vspd7.2.308-模拟串口工具) (2)需要一个调试助手,自动搜索监控电脑的COM口,用于调试程序(XCOM V2.0-串口调试工...
通过调用test_serial_communication('COM1', 9600)可以进行测试。 序列图 下面是一个使用序列图来展示Python串口自动化测试的示例。 小白开发者小白安装pySerial库等使用Serial类初始化串口对象使用write方法发送指令使用read方法接收数据,并使用decode方法转换为字符串使用close方法关闭串口请教如何进行Python串口自动化测试?...
上位机需要安装Python3和pyserial,运行test.py可以测试通信效果。 下位机需要使用RT-Thread Stdio进行编译,测试的板子是8MHz外部晶振的STM32F407VGT6开发板,需要连接串口1到PA9\PA10,连接串口2到PA2\PA3。其中串口1用作RT-Thread的控制台,串口2用来和上位机通信。
