多频率门禁卡复制器程序

红外遥控LED灯程序，三级调光。已做板过，可行。 使用PIC12F508芯片，汇编语言，懂行的请下吧。本人手机158 5770 1256 姜工。(Infrared remote control LED light program, three levels of dimming. Board has been done before, is feasible. Using the PIC12F508 chip, assembly language, knows the business to the next bar. I work phone 15857701256 Jiang.)

输入所需计算的秒数 得到这个秒数是多少小时数以及分钟数和秒数 (Enter the desired number of seconds to get the number of seconds to calculate how many hours and minutes, and seconds)

以款破解QQ2005的密码加密软件，里面还带有该程序所使用的ASM援代码。(to, as an abbreviation for crying; crack the password encryption software, which also contain the procedures used by ASM DAC code.)

实现了多功能电子定时器，包括计时，99秒倒计时和定时等功能。(Realize multi-function electronic timer, including the timing, 99 seconds countdown timer functions.)

本文件为通用型变频器控制键盘程序源代码，采用AT89C51芯片，汇编语言。希望能给变频器爱好者提供参考。(This document is general-purpose inverter control keyboard source code, using AT89C51 chip, assembly language. I hope to give fans a reference frequency.)

说明：  cop2000实现无符号数乘法——两个8位无符号数相乘，所乘结果是16位，采用原码一位乘，在计算时，用乘数寄存器的最低位来控制部分积是否与被乘数相加，然后右移部分积和乘数，同时乘数寄存器接收部分积右移出来的一位，完成运算后，部分积寄存器保存乘积的高位部分，乘数寄存器中保存乘积的低位部分。(Cop2000 implements unsigned number multiplication-multiplication of two 8-bit unsigned numbers. The multiplied result is 16 bits. When calculating, the lowest bit of multiplier register is used to control whether or not the partial product is added to the multiplier, and then the partial product and multiplier are moved right. At the same time, the multiplier register receives the right-shifted bit of the partial product. After completing the operation, the partial product register saves the product. The higher part, the lower part of the product is saved in the multiplier register.)

说明：  数码管时钟 电子钟 时分秒 可调时分 基本功能 （1） 可由按键调整时间 （2） 可整点报时（“嘟、嘟”声） （3） 可设定时，定时时间到发出“嘟、嘟”声 显示器件可选 段式LED显示或者LCD模块显示，嘟嘟声可选用蜂鸣器。(Digital tube clock electronic clock hour minute second adjustable time basic function (1) The time can be adjusted by pressing the key (2) Time can be reported at the same time ("beep, beep") (3) It can set the timing, and the "beep, beep" sound will be emitted when the timing is up to Segment LED display or LCD module display can be selected for display device, and buzzer can be selected for beep sound.)
