在python3.5中使用serial模块进行串口通信,通过while 1循环进行持续性的设备通信,但是第一个设备完成之后对下一个设备进行通信会有问题:Attempting to use a port that is not open 一下是我的代码: import serial import time import base64 import hmac import pymysql from esptool import ESP8266StubLoader from...
Gangge_port->setReadBufferSize(8192); //数据缓冲区长度 connect(Gangge_port,&QSerialPort::readyRead,this,&SerialTool::Receive_data,Qt::DirectConnection);//连接串口接收信号与槽函数 //第5个参数一般不填,为默认值 Qt::AutoConnection ui->portname->setEnabled(false); ui->boundrate->setEnabled(...
在调试程序时发现,若改成在slave端进行消息的收发, 发现消息发不出去,当然也收不到回执的OK消息,python发送端和c接收端的收发都是read/write,说明master是read/write、slave是port_recv, 也就是说pty对应master ,用于read write ;tty对应slave用于port_recv… 为避免别的设备占用tty的slave口,笔者曾想着把slave这...
