ad0831模数转换必须，很哟用的，我也是找了好久哦，大家一起分享把！...

这是一段开始学单片机时写的LCD程序，基于普通的51单片机，在KEIL环境上开发的。-This is a period of time began to study single-chip LCD written procedures, based on the ordinary single-chip microcomputer 51, in KEIL environment developed.

ST9720控制器的12864液晶程序，同时兼容12232，本程序使用串行接法。只需三个管脚。-ST9720 LCD controller 12864 program is compatible with 12232, this program uses a serial access method. Just three pins.

键盘与显示 4*4键盘 8个数码管轮流扫描作动态显示 硬件电路需要74LS138 cd451 -Keyboard and display 4* 4 keyboard 8 digital tube rotation scanning circuit for dynamic display hardware need 74LS138 cd451

freescale HC12_A64例程 -Freescale HC12_A64 routines

tcp_ip协议栈的ucos代码，主要用于嵌入式系统开发，已经移植到51系统单片机中，通过keil可进行编译，ucos经过最简化改造！特别推荐-tcp_ip CENTER protocol stack code, mainly for embedded system development, has been ported to 51 SCM system, through c51 can be compiled after the most simplified CENTER transformation! Preferred!

ds1820+1620液精显示时间，温度-ds1820+ 1620 precision liquid display time, temperature

这是关于DS18B20的读写程序,数据脚P2.2,晶振12MHZ 温度传感器18B20汇编程序,采用器件默认的12位转化,最大转化时间750微秒 显示温度00到99度,很准确哦~~无需校正!-DS18B20 on literacy, data P2.2 feet, 12MHZ crystal temperature sensor 18B20 assembler, using the default device into 12, the largest 750 microsecond conversion time show that the temperature from 00 to 99 degrees, very accurate ~ ~ Oh, no correction!

在Keil uVision3环境下开发的，用12864显示图片和字符和汉字程序-Keil uVision3 environment in development, and show pictures and 12,864 Chinese characters and procedures

硬件协议栈芯片W3100A和51单片机实现tcp客户端程序，在keil51环境中-hardware protocol stack and 51 W3100A chip MCU tcp client, in keil51 environment

关于单片机的按键程序,实现按一下,反应一次-Button on the SCM process, click the realization, the reaction time
