单片机拨号防盗报警器0、9数码管节显示

这是从网上找来的一个比较典型的PID处理程序，在使用单片机作为控制cpu时，请稍作简化，具体的PID 参数必须由具体对象通过实验确定。-It is found from the Internet a more typical PID process, as a control in the use of single-chip cpu, please make some simplification, the specific parameters of the PID must be determined through experiments at specific audiences.

步进电机控制,LCD显示-Stepper motor control, LCD display

基于时间触发调度器的PID控制，程序所用期间为C515，PID带有抗死锁功能-Time-triggered scheduler based on the PID control, the procedure used for C515, PID with anti-lock function

交通灯控制的简单程序，通过此程序，可以实现简单的交通灯控制设置-Traffic lights to control a simple process, through this procedure, you can realize a simple control set of traffic lights

LCD 显示屏由三片控 制，每个内部带有6 （512字节） 的RAM 对应关系如右图所示 片选对应表：

这是一个51单片机与PC的通信系统：利用3*4小键盘输入0~9的一串数字（不大于5），通过8051自带的串口发送给PC并显示在系统的6位LED上；单片机接收上位机的输入并显示在LED上。8051串行口经232电平转换后，与PC机串行口相连。PC机使用串口调试应用程序V2.2.exe，实现上位机与下位机的通讯。-This is a 51 microcontroller and PC communication system : use 3* 4 0 small keyboard input of a bunch of nine-figure (no more than 5), by 8051, bringing their serial sent to the PC and display system in the six LED; SCM receiving PC input and displayed on the LED on. 8,051 by 232 serial port-level conversion, and the PC serial port connected. PC using serial debugging applications V2.2.exe achieve PC and the next crew communications.

此程序是通过位选选取那位显示来实现数码管的显示。-This procedure are selected through the bit that shows the election to achieve digital tube display.

本文介绍的I2C未来的两个扩展方向：热插拔和远距离通迅，其中包括电路设计。-This article describes the extension of the I2C next two directions: hot swap and long-distance Communications, which includes circuit design.

51在多机通讯时可采用此方式，3线式，忙时可无限等待，闲时传输速率高-51 in the multi-machine communication use this form, a three-line, busy waiting for an unlimited time, in his spare time high speeds
