KEY scanning line inversion method. Asm

步进电机控制的源计算机实验，有自己的传递平台，可以在ASM中使用

用89C51，外接晶振，复位电路，二个数码管，二个按键，做一个电子秒表，具体要求为用按键起停电子表，可用按键设计倒计时时间(如10S，20S，60S),并启动倒计时功能,能用按键选择以上两功能之一-With 89C51, an external crystal oscillator, reset circuit, two digital tube, two buttons, making an electronic stopwatch, and specific requirements for the use button start-stop electronic watches, key design can be used countdown time (such as 10S, 20S, 60S), and start the countdown function, can be used for more than two buttons select one of the functions

输入高电压时直流无刷电机的控制程序,可使用在家庭,工厂等没有直流电源的地方-Importation of high-voltage brushless DC motor control program, you can use in the home, factories, and other places there is no DC power supply

这是一个流水灯加汽灯控制程序。采用四位的拨码开关，低电平有效。-This is a wasted signals Yiding control procedures. The use of dial-4 switches, low-level effective.

BASM_for_Beginners.是DELPHI开发工具嵌入汇编语言,介绍了两种语言的接口,其使用语法-BASM_for_Beginners. Yes DELPHI embedded assembly language development tools, the introduction of the interface in two languages, the use of grammar

这是一个汇编代码简单修改的工具，还算是蛮经典的一个。-This is a simple modification of the tool assembly code, is actually quite pretty classic one.

该项目是数字时钟的使用RTC DS12C887和8051微控制器（AT89C51）与时间设定，我们可以将它设置闹铃唯一不同的改进版本。它有助于理解在RTC的12C887设定报警的概念。该方案采用两个外部中断0和1，分别设定时间和闹铃。用于设置时间销P3中的微控制器8051的^2由低，这是外部中断0。对于报警设置微控制器的引脚P3.3由低是外部中断1。

鼠标控制CD-Audio播放程序！！！！！汇编语言-mouse control CD-Audio player! ! ! ! ! Assembly language

可以看一看源代码 与大家共享-look at the source code and share
