说明：  简单的流水灯控制和外部中断程序和键盘指针的应用(Simple light control and external interrupt water program and the application of the keyboard pointer)

详细描述了基于ADSP-21262的数字压限器的设计，给出了算法流程，可以根据其描述进行实现(A detailed description of the ADSP-21262 digital limiter based design, flow chart of the algorithm is given, according to the description of implementation)

stm32f4 的usb鼠标主机程序，简单的修改即可成为自己的工程(stm32f4 usb mouse host)

Elliptic Curve Diffie-Hellman Key Agreement Scheme

STM32的ADC程序，亲测可用。内有详细注释和说明文档，很好的参考资料。(STM32 ADC program, pro - test available. There are detailed notes and documentation, good references.)

能从SD卡读取MP3文件，并且识别后通过LD3320播放MP3，具体使用只需新建一个.ini系统文件存在sd卡，在里面设置好关键词并且所需播放的MP3文件即可(Read MP3 files from the SD card through the LD3320 play MP3 and identify specific use simply create a new the ini system files sd card exists inside set keywords and required to play MP3 files can)

stm32f103 lib header 头包含文件结构(stm32f103 lib header)

此程序可实现长度为8位，周期为255的m序列，此序列可当做伪随机信号发生器，模拟信道噪声。(This procedure can achieve the length of 8 bits, the m sequence of 255 cycles, the sequence can be used as a pseudorandom signal generator, analog channel noise.)

nrf905 接收机程序 89C52 验证通过 绝对好使(nrf905 receiver program 89C52 verified through absolutely so)

说明：  红外编码发生器程序 自己编写 调试成功 大家可以看看(IR code generator program written to debug their success we can see)
