本代码为本人在做一个项目时写的MSP430单片机读写FLASH芯片45DB041的源程序，包括基本通信函数，初始化函数，模式设置函数，整块FLASH读写，字节读写等多个函数。-The code for doing a project I am writing to read and write FLASH chip MSP430 single chip 45DB041 the source, including the basic communication function, initialization function, function mode is set, FLASH block read and write, byte read and write and so on a function.

本设计采用ATMEL公司的AT89S52单片机和红外遥控技术实现近距离无线通信的软硬件系统。为了使受控设备识别信号，设计一种数字信号编码系统，利用红外线将数字信号调制，而数据的解码则由另外的单片机完成，系统的实现简单。-This design uses ATMEL Corporation AT89S52 MCU and infrared remote control technology to achieve a short distance wireless communications hardware and software systems. Controlled equipment in order to enable the identification signal, the design of a digital signal coding system, using infra-red digital signal modulation, and data from other single-chip decoder completed, the system simple.
