AVR m16的开发板，本人制作。有Protel99的原理图和PCB图。可根据个人需要修改。-AVR m16 development board, I produced. There Protel99 the schematic diagram and PCB Fig. Can be based on individual needs to be revised.

是一个为地铁施工现场开发的人数监控系统，使用ATMEGA16单片机做的，并用了红外传感器。-Is a subway construction site for the development of the number of monitoring systems, using ATMEGA16 microcontroller to do, and use the infrared sensor.

急救车与交通灯）（1）南北与东西方向，每个方面由红黄绿三个灯控制（2）南北向：　红（30秒），黄（5秒），绿（25秒）　　　东西向： 红（35秒），黄（5秒），绿（25秒）　　　上述基本参数可以根据实际情况自行调整，灯的变化规律与实际路口规律相同，绿灯在最后5秒钟时，黄灯亮，然后红灯亮，不允许两个方面同时亮绿灯。（3）绿灯的时间显示在数码管上进行显示。（4）可以通过一个开关控制，当开关信号为0时，整个交通灯全灭提高要求：（1）设计一个紧急控制开关信号，当紧急开关信号为1时，两个方向的灯全为红灯。紧急开关撤消后，按照开关按下之前的状态继续运行（其参数要保存）。（2）设计一个夜间行车开关，当开关按下后，两个方向都只有黄灯闪烁，其它灯熄灭。（3）设计两个方向的亮时时间可调。-emergency vehicles and traffic lights) (1) North and South and east-west direction, each with three yellow-green from red lights control (2) to the north and south : red (30 seconds), yellow (5 seconds), Green (25 seconds) to things : red (35 seconds), yellow (5 seconds) Green (25 seconds) above basic parameters can be adjusted to the actual situation, the light changes with the actual law of the same intersection, the green light in the final five seconds, the yellow light is on, and then a red light, bright, not two fronts simultaneously bright green. (3) the green light at the time displayed on the digital display control. (4) can be controlled by a

* 本程序包含控制外部液晶面板的4-BIT控制模式子 * * 程序。这些程序是专门为 MCU201 workshop演示板 * * 设计的。但它也可作为其他类型的使用 KS0066U控 * * 制器的液晶面板的控制程序。-* The procedures include external LCD control of the four-BIT- control mode** procedures. These procedures are specifically for MCU201 workshop demonstration board** design. It can also be used for other types of use** KS0066U control system for the LCD control procedures.

protel99se的十来个元器件库文件。希望对大家画图的时候能起到帮助。-Protel99SE library file of a dozen components. Wish to draw a time when everyone can help.

本文从远传抄表的传输方式以及发达国家的家庭网络技术，较全面的介绍了国外远传抄表系统，对我国智能远传抄表系统新产品的研发有一定的参考价值。-This text is based on the transmission means of telemeterrecording and household network technologies of in developed countries，more overall introduction the system of telemeterrecording abroad，There must be certain reference value to the research and development of new products of intelligent telemeterrecording system.

按键扫描 51单片机加8279 8279通过74LS 138译码器扩展4×4键盘、6位显示器。 由3-8译码器对SL0～SL2译出键扫描线，由另一3-8译码器译出显示器的位扫描线，并采用了编码扫描方式。 为了防止出现重键现象，扫描输出线高位SL3不参加键扫描译码。CPU对8279的监视采用了查询方式，故8279的中断请求信号IRQ悬空未用。 -Scan button 82,798,279 plus 51 single-chip decoder 74LS 138 through the expansion of 4 × 4 keyboard, the display 6. From 3-8 decoder SL0 ~ SL2 translated to the key scanning line, by another 3-8 decoder translated display scan line, and uses code scanning. In order to prevent the emergence of the phenomenon of re-key, scan the output line does not take part in high level SL3 scan decoding keys. CPU on the 8279 surveillance using the query mode, the 8279 interrupt request signal IRQ left unused.
