该文件的内容是设计一个五层楼的电梯控制装置,要求每层楼根据需要控制设上下控制按键及按键指示灯,全部楼层只设置一个当前楼层显示 电梯内设开关门按键 各楼层按键及指示灯,开关门要有声响提示 每层楼高度为0.30米,楼层全高1.5米-the contents of this document is to design a five-storey building in the lift control device on each floor under the requirements necessary to control the upper and lower control buttons located buttons and lights, all floors can provide a current show floor elevator door keys internal switches on each floor of buttons and lights, switches doors have audible alert signal height of each floor 0.30 meters, the entire floor 1.5 meters high

蜂鸣器在单片机上的应用,汇编语言,附原理图及说明学习文档 蜂鸣器的正极性的一端联接到5V电源上面，另一端联接到三极管的集电极，三极管的基级由单片机的P2.4管脚通过一个与非门来控制， 用户可以通过程序控制P2.4管脚的置低和置高来使蜂鸣器发出声音和关闭。 蜂鸣器的声音大小及音调可以通过调整P2.4管脚的置高时间及输出的波形进行控制，这一点可以在调试程序的时候来试验。-On the buzzer in single-chip applications, assembly language, with a schematic diagram and instructions to study documents the positive polarity of the end of the buzzer connected to the 5V power supply above, the other end connected to the transistor" s collector, the base level by the single-chip transistor Machine P2.4 pin through a NAND gate to control, the user can be programmed to set pin P2.4 low and set high to make the buzzer sound on and off. Buzzer sound size and pitch can be set by adjusting the P2.4 pin of the high time and output waveform control, and this point could be the time to test the debugger.

Quoted from the author Igor Skochinsky In July I had the honor to speak at the Recon conference in Montreal, Canada. It was my first conference but I really liked the experience. I hope I’ll be able to attend it in future. The presentations were recorded and hopefully will appear on the Recon site soon but for now you can check out the slides . I have also uploaded some of the tools I mentioned, most notably various filesystem extractors compiled for Win32 .
