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.

The sample software includes, common library, peripheral APIs, and test modules for the APIs. The common library include startup file, standard definition and header files, processor specific setup module, generic interrupt related APIs, timer routine, and scatter loading file. The peripheral directories include, GPIO, PWM, Real-time clock, timer, SPI, I2C, Watchdog timer, UART, external interrupt, etc.
