Serial Port Comm

Comm1.CommName := '//./' + Trim(combx_Port.Text); 目前串口大于20  用上面方法解决的 网上也有上面方法解决如下错误的. 若是您已会应用SPCOMM且涌现10个以上的串心题目 请改一下串心名 COM1.CommName='//./com18'; 便如许减'//./'就好了我也没有晓得甚么回事....... 比方 Comm1.CommName := '//./'+ComboBox1.Text; //./com18是win] 如果你已经会使用SPCO

In this tutorial we will learn How to communicate with an external device like a microcontroller board or modem using the Serial port of a windows PC(Windows XP,7). The software is written using C language and communicates with the Serial Port using 

In this article, I will use three asynchronous conferencing--select, poll and epoll on serial port to transmit data between PC and Raspberry pi. Outline Character device file of serial port Naive serial communication Asynchronous conferencing Select

This is a tutorial on how to program the Serial Ports on your Linux box.Serial Ports are nice little interfaces on the PC which helps you to interface your embedded system projects using a minimum number of wires.In this tutorial we will write a smal

ubuntu12.04使用USB转串口时出现权限不够问题,如下 权限不够 解决办法: 通过增加udev规则来实现.步骤如下:创建文件/etc/udev/rules.d/70-ttyusb.rules在文件内增加一行KERNEL=="ttyUSB[0-9]*", MODE="0666"重新插入USB转串口设备,普通用户就有权限访问了. 70-ttyusb.rules文件还有另一种写法,先用lsusb查看USB转串口芯片的idVendor和idProduct#lsusb

前几天公司有通过搭载Android系统的开发板来使用打卡机统计数据的需求,对于攻城狮来说就需要在Android平台上读写打卡机的串口,在网上搜索一些东西之后发现了在google code 上的android serial port api可以用,墙了之后拿到源码发现还有demo,不错不错,我这个帖子就通过serial port api的源码简单得实现一个读写串口,这个当然是在native写的,如果还有哪些童鞋不清楚android上使用jni和native的话可以跳转到我的上篇帖子 点我点我 在A

Similar with the linux version, this article would demonstrate how to write a simple windows . I divide the 2 operations : write and read into 2 threads. Of course, one could call ReadFile and WriteFile (those are mapping to read/wrrite function in l
