Keil C51 example

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

这个是液晶模块1602A用于单片机AT89S52的C语言驱动头文件.这个头文件不是普通的头文件，笔者在其中加进了很多自己的东西。而且经过自己的实际验证是可以用的。 　　有了该文件，你可以不用看1602的DATASHEET就会使用。-This is a LCD module 1602A for the single-chip AT89S52 the C language driver header file. This header file is not an ordinary header files, in which the author added a lot of our own things. But after their own actual authentication can be used. With the file, you can not watch the 1602 will be used DATASHEET.
