这是一本单片机的初学者教程，简单易学。是单片机初学者的首选-This is a tutorial for beginners SCM, easy to learn. Is the first choice for beginners Singlechip

采用AT89C51单片机进行编写，步进电机端口:P1.0,P1.1,P1.2,P1.3,遥控器接口p3.2喇叭p3.7-AT89C51 single-chip microcomputer used for the preparation, stepping motor port: P1.0, P1.1, P1.2, P1.3, remote control interface P3.2 Speaker p3.7

这是用VHDL来设计80C51的开发过程和代码！ 处女作，大家一定要顶啊！-This is 80C51 VHDL design to the development process and code! The first time, we must Crack!

c51程序原理. .-principle

This a program which performs addition,subtraction,multiplication and division of two 4 bit binary numbers..therefore it is called as 4 bit binary ALU..if u have any doubt,then mail me at prem_bombay@yahoo.co.in -This is a program which performs addition,subtraction,multiplication and division of two 4 bit binary numbers..therefore it is called as 4 bit binary ALU..if u have any doubt,then mail me at prem_bombay@yahoo.co.in

基于Proteus的正反转可控的步进电机的仿真，内有源代码。-Based on the positive inversion Proteus controlled stepper motor simulation, within the source code.

红外线遥控器按键检测程序. 通过检测两次下降沿之间的时间差判断接受到的数据位. 已经通过了测试,能够正确区分出32bit数据的遥控器按键键值. 具有数据重发功能,但是数据的重发有点频繁. 使用晶震频率为11.0592MHz,所有定时值都是基于这个频率计算. 占用很少量的CPU时间,使用了外部中断0接受数据,定时器0进行计数, 定时器1作为串口的波特率发生器(Band = 9600).-Infra-red remote control button detection program. By detecting falling edge twice to determine the time difference between the received data bit. Has passed the test, could correctly distinguish 32bit data button remote control key. With data re-issued, but data a bit of re-issued frequent. Zhenyuan frequency of use of crystal 11.0592MHz, all timing values are calculated based on this frequency. occupied by small quantities of CPU time, use the external interrupt 0 to accept data, timer 0 to count, timer 1 as a string port baud rate generator (Band = 9600).
