一个电表的程序，能够直接使用，该芯片使用的是7169，请大家参阅-a meter procedures can directly use, the chip is used in 7169, please refer to

本程序主要通过外部中断INT0及3.3端口读取PS2键盘值并通过LCD1602显示，键扫描码的解码通过数组方式解码，程序的解码功能主要针对数字及大小写字母和常用标点符号 硬件描述：PS2键盘的时钟线（clk）接89S51的INT0（P3.2）,数据线data接（P3.3） LCD的控制端口分别为： RS = P2^7，RW = P2^6，EP = P2^5，数据端口为P0，液晶显示偏压VL必须接 -This procedure mainly through external interrupt INT0 and 3.3 read PS2 keyboard port value through LCD1602 display, key scan code decoder way through an array of decoding, the procedure for decoding function of the major figures and upper and lower case letters and punctuation marks commonly used hardware description: PS2 keyboard clock line (clk) then 89S51 the INT0 (P3.2), data lines data access (P3.3) LCD control port, respectively: RS = P2 ^ 7, RW = P2 ^ 6, EP = P2 ^ 5, data ports for the P0, LCD bias VL must be received

液晶驱动程序,提供通用液晶驱动的框架,可以嵌入各种操作系统,提供了向上的接口-LCD drivers, LCD drivers provide a common framework that can be embedded in a variety of operating systems, provides a progressive interface

一个只有1台计算主机的智能安防报警系统,大规模系统的工作原理是一样的,自己扩展就可以了-Only 1 of a host of intelligent computing security alarm system, large-scale system, the working principle is the same, their expansion can be a

DDS集成芯片AD9851的应用，用键盘输入任意频率，液晶1602显示，由DDS输出正弦波-DDS chip AD9851 applications, using keyboard input at any frequency, liquid crystal display 1602, by the DDS output sine wave

ppt格式的，arm7的一个讲座的一部分，对设计lcd非常有用-ppt format, arm7 of a lecture as part of the design is very useful lcd

Keil70完全安装文件-Keil70 complete installation

MCS-51智能反编译器。可将51单片机的bin或hex文件反编译为汇编码。仅用于学习用途，否则后果自负。-MCS-51 Intelligent compiler. May 51 SCM bin hex or documents compiled for the Department of Anti-coding. For learning purposes only, otherwise the consequences conceited.

为了进一步理解上述方法如何在编程中得以实现，在此提供了1个用C51单片机编程语言编制的8个按键的键处理程序，以供参考。该程序在KEIL C51 V6.02/uVsion2 demo编译环境下编译通过-In order to further understand how the above method to realize programming, provided in the C51 single-chip microcomputer with a programming language produced by the eight key key procedure for reference. The program in the KEIL C51 V6.02/uVsion2 demo compiler compiler environment through
