红外数据发送接收程序，实现温度和时间信号的发送与接收
结合红外通信理论与单片机实际应用,以AT89S52单片机为核心，包含红外数据采集发射和红外数据接收两大模块。为了方便测试，发送端采用数字温度测量器件DS18B20测量本地温度。发射模块检测到接收模块发送的命令后，会执行相应的动作，把温度和时间值数据，按照协议用38K方波发送出去。接收模块的一体化红外接收头检测到38K方波后，对应输出低电平，接收模块的单片机计算接收头的高低电平时间，判断是否为二进制“0”或者“1”，实现数据的解码并在LCD1602上显示。最终完成测温与红外数据传输的目的。

AT91RM9200的USB host和USB device的代码ADS1.2.
USB-Device测试程序:
因为程序运行在SDRAM中，所以要先初始化SDRAM（可用basic boot程序初始，之后不能复位或断电），再运行此程序，程序运行后连接USB端口，计算机会提示检测到新硬件，安装硬件驱动程序atmusb6119.inf
后计算机会把USB端口虚拟为一个串行的端口使用-AT91RM9200 the USB host and USB device code ADS1.2.USB-Device test procedure: Because the procedure is running in SDRAM, and so we have to initialize SDRAM (available for the initial basic boot procedure, followed by Can not reset or power off), then Run this program, the program to run after connecting USB port, the computer will be prompted to detect the new hardware, installing hardware drivers after the computer will atmusb6119.inf virtual USB port to a serial port to use
