使用perl实现简单的串口通信；在串口上循环读写命令，可用于对串口通信的压力测试；(Using perl simple serial communication read and write commands on the serial loop, can be used for serial communication test pressure )

用C#语言编写串口通信程序详解，有代码有步骤(c#Serial programming steps detailed)

说明：  STM32F103ZET6由串口UART4接发信号(Signal Receiving and Sending by UART4 Serial Port)

一个很通用的51的串口通信程序，很好用，但仅供参考(A very universal serial port communication program 51, very good, but for reference only)

T9输入法中文源代码,包括演示程序,对做手机软件的人很有帮助！()

Writing Efficient C for ARM 基于ARM内核微处理器操作系统的移植 基于ARM的嵌入式开发(PDF ARM中国) ARM+DSP+CPLD开发板 s3c2410(arm9)protel99格式的原理图和PCB图(Writing Efficient C for ARM microprocessor-based ARM core operations transplantation of ARM-based embedded development (PDF ARM China) ARM DSP development board CPLD s 3c2410 (arm9) Protel format schematics and PCB plans)

基于F28335的SCI串口通信程序。本程序的特点是代码简单、高效。本代码共包含三个工程文件：1、基本通信（实现了最基本的通过SCI协议通讯的功能。上位机下发一个字符或字符串，下位机原样返回该字符或字符串）；2、SCI通信FIFO版（在1的基础之上启用了FIFO缓存接收或发送的数据）；3、SCI通信FIFO与中断版（通过启用FIFO功能减少对CPU资源的占用，且数据的发送与接收处理均在中断中完成）。此三个程序基本验证了F28335的SCI模块所有功能。(F28335 of SCI-based serial communication program. Features of this program is the code simple and efficient. This code contains a total of three project files: 1, the basic communication (via SCI achieve the most basic functions of communication protocols issued the PC or a character string as the next crew to return to the character or string.) 2, SCI communication FIFO version (on the basis of a FIFO buffer above the receive or transmit data enabled) 3, SCI communication FIFO and interrupt version (FIFO function by enabling reduce the occupancy of CPU resources, and sending and receiving data are processed in interrupt completed). The three basic procedures to verify the F28335 all functions of SCI module.)

CVI环境下的串口调试助手，主要功能有即时收发信息，显示波形，截图和保存数据(CVI environment serial debugging assistant, the main function includes immediately send and receive information to display waveforms, capture and save data)

串口通讯的一个类，已经在用，分享给大家。(serial port communication file.)
