自己动手，进入单片机的大门-yourself into the door MCU

一个变频器的代码,用msp430就能实现.低成本,可靠性也不错.-A code converter, can realize with MSP430. Low-cost, reliability was generally good.

can总线硬件控制器开发源代码-bus hardware controller can open source

93C46的C51读写程序-93C46 the C51 to read and write procedures

单片机在循环显示数字列的同时，采用查询方式控制数字的显示时间和音乐播放的开关。音乐低频信号由定时器采用中断方式产生。-SCM in circulation figures out show at the same time, using figures for the control of time- and the music player switching. Music low-frequency signals used by the timer interrupt way.

此程序可以实现两个单片机之间的相互通信；串口采用方式1工作，10位异步接受和发送，波特率可变，由定时器1控制；且含有校验-This program can be achieved between the two microcontrollers communicate with each other serial port mode 1 using the work of 10-bit asynchronous receive and send, variable baud rate, from Timer 1 control and contains a checksum
