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

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

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

ubuntu12.04使用USB转串口时出现权限不够问题,如下 Unable to open serial port /dev/ttyUSB0 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

If want to do iOS kernel debugging on A4 device, first you should install Virtual COM port (VCP) drivers. After has installed the driver on OS X Mavericks, plugin your device (for examle: iPod Touch 4, WiFi), then execute the following command: ls /d

Communication with ROS through USART Serial Port We always need to communicate with ROS through serial port as we have many devices like sensors, touch-screen, actuators to be controlled through USART serial protocol. After some investigation, I foun

串口数据监视工具 Serial Port Monitor可以在其它应用读写串口时监视串口数据, 很好用,但只有15天试用期.

发送十六进制比较直观,可以在上位机中直接获取十六进制的数据,然后在在上位机上将十六进制HEX转换成BIN(二进制)或者DEC(十进制)就十分简单有效了. 下面是在Arduino上怎么演示直接发送16进制. 详细请参考官方说明: http://arduino.cc/en/Serial/Print 代码如下: char tmp[] = "hello world"; void setup() { Serial.begin(); } void loop() { { Serial.println

CommMonitor  串行端口监视精灵是用于RS232 / RS422 / RS485端口监控的专业强大的系统实用程序软件.CommMonitor监视显示,记录和分析系统中的所有串行端口活动.这是追踪应用程序或驱动程序开发,串行设备测试和优化等过程中可能出现的问题的理想方法.还提供过滤.搜索.数据导出和强大的数据拦截功能,可以将指定端口的数据流.控制流信息拦截并保存下来,供分析之用.如察看端口状态的变化(波特率.数据位.校验位.停止位),拦截上行.下行的数据,处理速度快,拦截效率高,并可以以

前面转载的几篇文章详细介绍了UART.RS-232和RS-485的相关内容,可以知道,串口通信的双方在硬件层面需要约定如波特率.数据位.校验位和停止位等属性,才可以正常收发数据.实际项目中使用串口通信时,一般还需要设计一套通讯协议.那么设计串口通讯协议有什么需要注意的地方呢?本文以iPod.车载CAN解码盒及IoT设备EnOcean的串口通讯协议为例,对通讯协议数据帧的定义做一个简单的介绍和分析. 首先看Apple提供的文档<iPod_Accessory_Protocol_Interface_S

前面转载的几篇文章重点介绍了UART及RS-232.在工控领域除了RS-232以外,常用的串行通信还有RS-485.本文转载的文章重点介绍了RS-232.RS-422和RS-485. Overview This article explains the general concepts of the serial communication protocols RS-232, RS-422, and RS-485, including basic concepts like baud rate,

RS-232串口一度像现在的USB接口一样,是PC的标准接口,用来连接打印机.Modem和其他一些外设.后来逐渐被USB接口所取代,现在PC上已经看不到它的身影了.开发调试时如果用到串口,一般都是用USB转串口头,如下图所示.左图为USB-to-RS-232,右图为USB-to-TTL.USB-to-RS-232和USB-to-TTL因电气特性不同,所以应用场合也不同,不能互换.本文所转载的文章,重点介绍了RS-232和TTL串口的异同. One of the tools we use most
