C语言开发的数字钟程序，希望对大家有用！真是第二个文件！-development of the C language digital clock procedures in the hope that it may be useful right! The second document is!

包含了CS8900的接口原理图，用户可参考设计以便减少初次使用出错的概率

study arm step by step，本文从学习者的角度出发,分别描述了下面几部分内容: ARM 编程的基本知识,BOOT代码流程和功能分析,OS 中断程序的编写举例 和BOOT代码的流程图,希望这些内容能为初学ARM的朋友拨开迷雾,以最快 的速度和最短的时间走进嵌入世界的大们-study arm step by step, this article from the learner" s point of view, respectively, describe the contents of the following sections: ARM basic knowledge of programming, BOOT code processes and functional analysis, OS interrupt the preparation process and the BOOT code, for example, flow charts, hope that these content for beginners ARM" s friends fog, with the fastest speed and the shortest possible time into the world" s largest embedded in their

应用背景可用于各种需要PWM波的芯片，PWM的作用很多，也可以固定输出一个占空比和频率的方波，还可以再利用电源造SPWM关键技术STC12C5a60S2用定时器0产生1Khz的方波，通过按键可调节占空比，1-99%可调，通过数码管显示占空比，兼容普通的89C52， 只是运行速度不够快，频率要低一点，可以通过修改定时器的值改变频率

本程序是MP3的解码程序，可以用VC编译或者用GNU编译，可以运行在PC机上。 本程可以MP3文件解压为WAV文件 TEST 中的代码可以播放WAV文件 有兴趣的朋友可以把这段mp3程序移植到开发板上，这样就可以用开发板播放MP3了-MP3 decoding procedures that can be used with VC or GNU compiler compiler. can run on the PC. The process can decompress MP3 to WAV TEST document of the code can be broadcast WAV documents are interested friends this can be transplanted to mp3 development board, we can develop with the board to broadcast MP3

每次开机都将次数加1 并存储到EEPROM。这样就能直观的看到机器的使用次数。用P1口 LED做为显示，次数大于256是将溢出，按复位模拟开机 或者直接通过开关开机。-Each boot will add a number of times and stored in EEPROM. This will be able to see the intuitive usage of the machine. As with the P1 port LED display, frequency is greater than 256 is the overflow, according to reset the boot, or directly through the analog switch boot.

通过PIC16F877主控芯片操作ISD1760语音芯片，可以通过手动录音以后实现录音地址的提取。地址计算方法包含在注释中，音质好，可以满足大部分的需求。-PIC16F877 chip operations through the Master ISD1760 voice chip, can be achieved by manually recording after the recording address of the extract. Address calculation method is included in the notes, the sound quality is good, to meet the needs of the majority.
