这是我用汇编语言编写的计时器程序，通过计算机发命令开始倒计时，其中也有其他功能，但主要是倒计时，比较好用，这是个小程序，穿上来了表心意...

源码公开的MCS 51 单片机的宏汇编器 Macro Assembler of MCS MCS-51 micro controller Version 0.12 这是一个应届生写的习作 尽管这个软件A51 还未完全达到满意的效果不过与Keil 公司的A51 配合起来使用还是不错的 公开源码和文档的目的是希望能够给一些爱好者作为学习编译原理和C 程序设计的靶子同时也希望有更多的热心人参与修改源码直至更加完善 来自周立功公司-MCS 51 open-source SCM macro assembler Macro Assembler of MCS MCS-51 micro controller Version 0.12 This is a year of Health to write assignments A51 even though the software is still not yet fully satisfactory, however the effect of the A51 and Keil company with up or a good use of open source code and documentation which aims to compile a number of enthusiasts as a learning theory and C programming target but also hope that more and more enthusiastic to participate in modified source code until a more complete company from weeks Ligong

TMX320TCI6482 电路图，很难得才弄到！-TMX320TCI6482 circuit, it is difficult to have to get before!

利用单片机的定时器定时，令十字路口的红绿灯交替点亮和熄灭，实现主支路路口的交通信号灯控制（尽可能保持主线的畅通，即在通常情况下，保持主线的放行，只有在支线到达时，才放行支线），同时采用LCD显示倒计时时间及当前灯的状态-The use of MCU timer timing, so that the crossroads at the traffic lights turn out light and to achieve the main slip road junction traffic lights control (as far as possible the smooth flow of the main line, that is, under normal circumstances, to maintain the release of the main line, and only arrived at the branch only when the release branch), while using LCD display countdown time and the current state of light

介绍一种应用于实际工业生产现场中的大型LED显示系统的设计和研制。-A site used in the actual industrial production of large-scale LED display system design and development.

本设计采用ATMEL公司的AT89S52单片机和红外遥控技术实现近距离无线通信的软硬件系统。为了使受控设备识别信号，设计一种数字信号编码系统，利用红外线将数字信号调制，而数据的解码则由另外的单片机完成，系统的实现简单。-This design uses ATMEL Corporation AT89S52 MCU and infrared remote control technology to achieve a short distance wireless communications hardware and software systems. Controlled equipment in order to enable the identification signal, the design of a digital signal coding system, using infra-red digital signal modulation, and data from other single-chip decoder completed, the system simple.
