1、关闭串口
如果没有创建串口,关闭串口就会报错
SerialLibrary.Close Port
SerialLibrary.Delete All Ports
Run Keyword And Ignore Error 可以用该命令来忽略错误
2、添加串口
SerialLibrary.Add Port ${port} baudrate=${baudrate}
#baudrate, bytesize, parity, stopbits,timeout, xonxoff, rtscts, write_timeout, dsrdtr and inter_byte_timeout. write_timeout=120.1
3、打开串口,获取串口返回的字符编码
SerialLibrary.Open Port ${port}
${a} SerialLibrary.Get Encoding
log ${a}
4、往串口写如数据,注明输入字符的编码
SerialLibrary.Write Data
UTF-8
5、刷新端口
SerialLibrary.Flush Port
sleep 1
Flush port so that all waiting data is processed.
刷新端口,以便处理所有等待的数据。
6、读取串口输出数据
SerialLibrary.Read All Data
7、读取有效数据前,删除无效数据
SerialLibrary.Flush Port
SerialLibrary.Read All Data
SerialLibrary.Reset Output Buffer
8、退出串口
SerialLibrary.Close Port
SerialLibrary.Delete All Ports
9、Wait Until Keyword Succeeds 5X 3 运行直到成功
