AT24C02 read and write

用于储存大量数据，它有一个定时器，到一定数量，它会自动报警。-used to store large amounts of data, it has a timer, to a certain number, it will automatically alarm.

可以从计算机向WINBOND516直接下载程序的源码，调试单片机用，可不用编程哭-can WINBOND516 from the computer directly to the download source code, debugging MCU use Programming can not cry

频率计是用单片机89C51和几块数字电路几个三极管-Frequency meter is used and a few 89C51 single-chip digital circuit several triode

按键控制发光二极管熄灭，基于凌阳单片机开发 -Button control LED is off, Sunplus based on single-chip development

单片机系统用c语言编写关于两个PIC之间的通信的设计。。。本程序采用的单片机型号为PIC16F8- Single-SCM systems c language on the communication between two PIC design. . . This procedure used for the PIC16F877 microcontroller model

键盘扫描程序，逐行拉低，错位相交的方法实现-Keyboard scanner, progressive degrade realize dislocation intersect method

2个Cy7c68013之间的GPIF与Slave FIFO异步通讯方案，以及源码-2 CY7C68013 between GPIF and Slave FIFO asynchronous communications programs, as well as source

本代码是本人毕设所做的GPRS数传系统的软件部分，实现了PPP，UDP，IP协议的分层和打包，实现了嵌入式设计中的UDP/IP协议栈-the code is completed, I set up the GPRS data-transmission system software, to achieve the PPP, UDP, IP protocol layering and packaged to achieve the design of embedded UDP/IP protocol stack

这是参加电子设计大赛时的作品：红外遥控小车：用红外线通过一块AT89S52单片机发射信号即编码，并用红外接收头接收信号；接着再用另一块AT89S52单片机对红外发射出的信号编码进行解码，最后再用一块AT89S52单片机用解码所得码值编写程序后驱动步进电机。步进机功能启动后不仅能使受控小车向前后左右四个方向前进和转弯，而且还能控制小车再地上转动并留下方形或圆形等形状。-This is the time to participate in Electronic Design Contest works: infrared remote control car: Using infrared transmission signal through an AT89S52 microcontroller that is encoded and used infrared receiver to receive the first signal and then using the other an infrared emitting MCU AT89S52 code and decode the signal and finally an AT89S52 microcontroller then proceeds with the decoding key value of the preparation of procedures to drive a stepper motor. Stepper machine function activated not only make the car forward in a controlled direction and after about four turns, but also to control the car and then turned and left the ground such as square or round shapes.

nRF905开发，欢迎参考，演示了用905实现调频设计，程序用C51编写，特别具有可读性，
