本资料一共有几十个单片机基本程序代码，并带有详细的说明，非常适合单片机初学者！其实单片机不难学，只要多自己动手编写程序

工程师在用Keil开发程序时，在代码性能要求较高的场合，需要对代码段的执行时间作统计。比如在做LED显示屏软件扫描程序，或一些定时采集数据程序，如果在软件仿真的时候就能够清晰知道代码段的运行时间，那就可以对程序进行优化，或者插入汇编代码(asm)达到最高运行速度。 关键字:Keil DLL C语言 ASM 汇编-engineers in the development process with Keil, the code performance requirements higher occasions, need to block the execution time statistics. For example, in the software do LED scanning procedures, or some regular data collection procedures, If the software simulation time can understand clearly code of the running time, it can process optimization, or insert code compilation (asm2) to achieve maximum speed. Keywords : Keil DLL C language compilation ASM

编译环境：ICC AVR 6.31A 单片机：AT90S8515 PC.0出音乐信号，INT0，INT1分别接下一首、播放/暂停键 开机处于暂停状态，按下播放/暂停键开始放音，自动播放完8首，会再进入暂停状态。 所有的暂停状态都采用掉电模式。 -build environment : ICC AVR microcontroller 6.31A : AT90S8515 PC.0 musical signal INT0, INT1 respectively took one, Play/Zantingjian Boot suspended, press Play/Zantingjian start of audio, automatic broadcast End 8, will enter the state. All the suspended power-down mode is used.
