ht1621液晶驱动的测试程序，汇编语言编写-HT1621 LCD driver test procedures, assembly language preparation

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

本文件是单片机开发板STK500的使用说明，与大家共享-The present document is a single chip using the STK500 development board that share

可以用单片机做一个卡-SCM can be used to do a card

Keil C51使用详解-Keil C51 IDE

一个单片机驱动红外通信的程序,很有意义.当然你也可以举一反三,用作无线通信,也可以仿照该程序做蓝牙通信协议-A single-chip driver infrared communications procedures, meaningful. Of course you can learn by analogy, for wireless communications, modeled on the program can also do Bluetooth communication protocol

比较时钟的另类应用---模拟发送红外遥控的波形 比较时钟一般用来作一个固定的定时器，做系统时钟或固定的时钟任务，-Comparison of the alternative application of the clock to send the infrared remote control--- Simulation waveforms generally used for clock compared to a fixed timer, so the system clock or the clock fixed tasks,
