AT89C5131的接口驱动-AT89C5131 Driver Interface

用于Atmel单片机ISP下载的程序，该源码比起easy51更通俗易懂，且与easy51兼容，移植也容易。-for Atmel microcontroller ISP download procedures, the source easy51 more accessible than, but compatible with the easy51 transplant easily.

模拟交通灯，并带有数字显示的程序。初始时全为红灯，显示“HELLO”字样。然后交通灯以“红绿、红黄、绿红、黄红”四种状态做循环，而且黄灯会闪烁，每种状态都带有到数记时。当按下P3_2时，变成“红红”状态，并显示“STOP”字样！ -simulated traffic lights and figures with the procedure. When all of the initial red, shows that the "hello" words. Then traffic lights to the "black, red and yellow, green, red, yellow red" state to do four cycle, but the yellow light flashes, each state will have a few to remember when. When pressed P3_2, into a "red" state, and shows that the "STOP" word!

i2c的传输的驱动所需要的头文件 用mega16单片机实现-i2c transmission driven by the needs of the first documents mega16 MCU

本人所做项目中用51系列单片机(STC89C58RD)对OCMJ8*15B液晶屏进行数据写操作时所写的配套源代码,可以直接在keil7.0以上的版本中嵌入开发！应该说本程序有很高的实用价值（本人开发的产品已应用于实际工业控制中）-I conducted a series of 51 projects using SCM (STC89C58RD)* 15 OCMJ8 B LCD screen for data write operation written by supporting source code, keil7.0 directly on the above versions embedded development! It should be said that this program has high practical value (I development of the product has been used in practical industrial control)

掉电保护的一些基础-power off some of the basic protection

这是“led广告屏”程序，已经成功调试，希望对大家有用，谢谢！（最好配合51单片机和伟福编译器）-"led advertising screen" program has been successfully tested and we hope to useful, thank you! (Preferably with 51-fu SCM and compiler)

有关74hc080的一些相关资料，希望可以帮助大家，它多用于IC卡读取了！-74hc080 some of the relevant information, I hope can help everyone, it used the IC card reader!
