对于一个单片机初者来说一定想自己设计一个小系统吧・・这里提供了以89S52为核的小系统图和源程序！希望对刚学者有所帮助...

PWM波程序 可以用来控制电机调速，程序比较简单，这里只用了一个定时器就实现了。因为51单片机没有PWM波的寄存器，所以要自己用软件控制。-PWM waves program can be used to control motor speed, procedure is simple, here only a timer is realized. Because no PWM waves 51-series microcomputer to yourself, so with registers control software.

比较时钟的另类应用---模拟发送红外遥控的波形 比较时钟一般用来作一个固定的定时器，做系统时钟或固定的时钟任务，-Comparison of the alternative application of the clock to send the infrared remote control--- Simulation waveforms generally used for clock compared to a fixed timer, so the system clock or the clock fixed tasks,

51单片机扩展64K以上数据存储区的源码。 已经过测试-51 Single-chip extended data storage area for more than 64K of source code. Has been tested

这是一个接收单片机数据的软件,通过对接收的数据分析来显示相应的LED.目前只能显示一个LED,有时间会全部做好的,目前接收到的数据为0A0B0C,也就是从单片机发出来的数据为10,11,12,单片机的程序是a-This is a single-chip microcomputer software to receive, through the analysis of data received to display the corresponding LED. Currently only display a LED, will all have time to do a good job of currently received data 0A0B0C, that is, from a single machine sent to the data for 10,11,12, SCM process is a
