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.

CY7C63723的完整固件CY7C63723 cy7c63001相比有优势。
Cy7c63723的完整固件
cy7c63723和CY7C63001相比，他的优点是不需加太多外部器件（包括晶振），这样就简化了电路设计，也节省了成本。
本程序就是CY7C63723的完整固件。
-Cy7c63723 the integrity and firmware cy7c63723 CY7C63001 compared He has the advantage of not increase too many external devices (including Crystal Oscillator), thus simplifying the circuit design and cost savings. The procedure is a complete firmware CY7C63723.

原理是，通过8279来实现8 * 2键盘的控制扩展…
实现原理是由8279的8*2键盘控制373扩展输出口，由一位片选信号线连接的8088CPU的一个地址上，8279的每一个键值控制8088里面的每一套方案，由8088控制373扩展口输出给单色灯，实现节日灯的效果。-Principle is that by 8279 to achieve the 8* 2 keyboard to control the expansion of output 373, by a chip select signal lines connected to an address on 8088CPU, 8279 every 8088 key control inside each set of program control 373 by 8088 expansion of output to the monochrome lights, festive lights to achieve results.
