如果按键盘上的“a”，您可以在计算机的终端中看到“继电器已打开”。

读写SD卡程序,是已经调能过的,还有FAT16文件系统-SD card read and write procedures, which have been transferred to off, as well as FAT16 file system

这是一个arm做的无线收发的程序.可以实现无线数据采集系统。代替了有线传输。而且传输速率高。-A wireless data transfer program that using ARM. It can be a wireless data collecting system that replaced wiredly transfer. And the transfer speed is high.

0――999计数器。在STC89C52单片机下开发的程序，可实现自动0――999计数。-0- 999 counters. At STC89C52 procedures developed under the single-chip microcomputer can automatically achieve 0- 999 counts.

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。

一个用于ARM的基4/基5定点FFT算法，原作者是JDB，后来我扩展过16和256点的计算并用在项目中了，感觉速度还不错。现在重写了基于Linux GCC4的测试程序，可供使用者评估参考。建议安装FFTW3用来精确评估测试结果，相关范例已经在代码中了。-Radix 4/5 FFT routines supporting 16/64/256 and 20/80 calculations. The source originally contributed by JDB, I had extended 16 and 256 candidates and used it in our project it has been verified as fast and stable. Now we add some test vectors running on Linux with GCC 4 for testers who want to use or just evaluate it. Installing FFTW3 is recommended for evaluating the code exactly.
