该文档包含了基于c8051f020的各种源码，包括AD、DA，串口，定时器，IIC以及时钟键盘等，很具有学习意义-This document contains a variety of source-based c8051f020, including AD, DA, serial port, timers, IIC and clock keyboard, it is with learning the meaning

atmega32 和RS485的通讯，已经在电路板上测试通过，RS232相对简单一点，RS485需要对控制收发信号处理一下，并且需要RS232转RS485工具来验证收发是否正确-atmega32 and RS485 communication, has been tested in the circuit board, RS232 relatively simple point, RS485 transceiver control signals need to deal with you, and will need RS232 to RS485 transceiver tools to verify the correctness of

最流行的mifare卡读卡器全部源代码，实现有全部功能-most popular mifare card reader all of the source code, achieving full functionality

本系统采用MSC-51系列单片机ATSC51和可编程并行I/O接口芯片8255A为中心器件来设计交通灯控制器，实现了能根据实际车流量通过8051芯片的P1口设置红、绿灯燃亮时间的功能；红绿灯循环点亮，倒计时剩5秒时黄灯闪烁警示（交通灯信号通过PA口输出，显示时间直接通过8255的PC口输出至双位数码管）；车辆闯红灯报警；绿灯时间可检测车流量并可通过双位数码管显示。本系统实用性强、操作简单、扩展功能强。 -The system uses MSC-51 series single-chip ATSC51 and programmable parallel I/O interface chip 8255A-centric device designed to control traffic lights, can be achieved in accordance with the actual traffic flow through the P1 port 8051 chip set red, green fuel Liang function of time traffic light cycle, the countdown five seconds left when the yellow light flashing warning (traffic lights through the PA output signal indicates the time directly through the PC port output 8255 to double-digits) vehicle alarm闯红灯 green time traffic flow can be detected through a double-digital display. The system practical, simple and strong extensions.
