用串口通信的方式实现双机备份，串口采用了 mscomm控件。

实现多线程串行通讯接口源程序-multi-threaded serial communication interface source

想必大家一定想了解16650吧,现在上专给大家共享-definitely something we would like to know the 16,650 it and on to share expertise

用单片机I/O口模拟串口通信，有两种方法，节省硬件，实现简单。-MCU I/O simulation mouth serial communication, there are two ways to save hardware, simple implementation.

用VB实现RS232接口通信，能和单片机通信的上位机程序。-RS232 interface using VB to achieve communications, energy and single-chip PC communications procedures.

一个非常完整的川口通讯源程序，我费了很大功夫才把他找到。-a very complete source Kawaguchi communications, I spent a lot of time and energy only to find him.

IIC_slave硬件的代码，已经经过FPGA验证-IIC_slave hardware code, and has been verified through FPGA

c8051F221的SPI总线通信(收)-c8051F221 SPI Bus Communication (received)

MCU读写U盘源程序（无需子程序库基于文件系统）, MCU读写U盘源程序（无需子程序库基于文件系统）-MCU literacy U-source (without subroutine library based on the file system), MCU literacy U-source (without subroutine library based on the file system)

本源码采用spcomm串口控件，接受数据采用线程方式，这是一个串口测试工具，可以用来做串口监听等。非常适合使用delphi开发串口程序的程序员做参考！-the source used spcomm Serial Control and accept data using threads, it is a serial testing tools can be used to do Serial wiretapping. Delphi is very suitable for the development of Serial procedures programmers refer!
