51单片机实现简易函数信号发生器功能（正弦波、方波、三角波）(51MCU，sin ，pluse，and so on)

基于StC89C52单片机的nRF24L01驱动及应用程序， 已经调试成功(Driver and application program of nRF24L01 based on STC89C52 MCU has been debugged successfully.)

这是一款单相电子式无线防窃电电能表程序，可实现无线抄表功能。(This is a single-phase electronic energy meter wireless anti-theft program, enabling wireless meter reading function.)

说明：  本系统采用下位机负责模拟数据的采集,从51单片机负责采集数据，并应答主机发送的命令，上位机即主机是负责处理接受过来的数字量的处理及显示，主机和从机之间用RS-485进行通信。这样用户可以在上位机上编写各种程序对文件中的数据进行有效查询和分析,有利于工业过程的长期正常运行和检查。该系统采用的是STC89C52单片机，此芯片功能比较强大，能够满足设计要求。(In this system, the lower computer is responsible for the acquisition of analog data, and the 51 single chip microcomputer is responsible for collecting data and answering the commands sent by the host computer. The host computer is responsible for processing and displaying the received digital quantity. The communication between the host computer and the slave computer uses RS-485. In this way, users can write various programs on the upper computer to effectively query and analyze the data in the file, which is conducive to the long-term normal operation and inspection of industrial processes. The system uses STC89C52 single chip microcomputer, which is powerful and can meet the design requirements.)

单片机密码锁 硬件加程序，无密码压缩，课程设计(Single-chip code lock)

基于单片机的一些基础应用 和硬件设计以及综合设计(89c51Integrated application hardware design)

第一个发光管以间隔200ms闪烁 第一个发光管以间隔200ms闪烁 (The first light emitting tube at intervals of 200ms blink first light emitting tube flicker at intervals of 200ms)

说明：  它是关于80C51单片机的原理介绍和使用其开发的过程，有具体的实例。(It was introduced on the 80C51 microcontroller and use the principle of its development process, with specific examples.)

类似IE和WordPad的工具条，还有两个极像IE和Wordpad的例子(The toolbar which likes IE and WordPad, and two examples which like IE and Wordpad)
