说明：  单片机原理与应用课件 对单片机可以全面的认识和了解(Simple keyboard microcontroller design courses play a role in achieving key)

液晶显示模块YB12864ZB使用说明书(LCD module YB12864ZB manual)

此代码是基于NXP公司的串口扩展芯片SC16IS752的驱动程序。此芯片可以用IIC或者SPI接口进行控制，两种程序都有，并且是基于C51的代码。简单易懂，方便进行移植。(This code is based on NXP s serial port expansion chip SC16IS752 driver. This chip can be used IIC or SPI interface control, both programs have, and is based on the C51 code. Easy to understand, easy to transplant.)

利用51单片机结合超声波模块，编写的测距触发系统，程序可移植性好，具有人机界面，选用市售4脚传感器结合51机就可模拟，硬件简单。(The obstacle detection unit 51)

对初学单片机非常实用的一些小程序老师写的 这是第二部分(right novice SCM some very practical procedures for the teacher to write small, which is the second part)

这是一个厅在ＤＳ１８Ｂ２０数字温度计的Ｃ程序，精确度达到０．５摄氏度(This is a digital thermometer DS18B20 Office of C procedures, accuracy of 0.5 degrees Celsius)

使用方法： 程序设置了ENC28J60的IP为192.168.0.15，模块通电后与电脑的网口用网线连接起来， 设置电脑的本地IP为192.168.0.**（**自定），网关为192.168.0.15,其他默认，配置 成功后便可以arp或ping模块。 打开浏览器，在地址里输入http://192.168.0.15/123456可打开开发板简单网页，页 面上通过按键来控制开发板LED的亮灭。(Use: setup the ENC28J60 of IP to 192.168.0.15, the module is powered on the computer' s Ethernet port using a cable connection up to set the computer' s local IP 192.168.0.** (** Custom), the gateway 192.168.0.15, default configuration is successful, it will make arp or ping module. Open the browser, enter the address http://192.168.0.15/123456 to open the development board simple web pages, and page keys to control the development board LED light off.)

一种简单的心率测量系统设计，能显示并进行上下限报警(A simple heart rate measurement system design, and upper and lower alarm)

说明：  本程序使用8051F330为主控100M鉴相VCO锁频输出(This program uses 8051F330 as the main control 100M phase detection VCO frequency lock output)
