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.

特此感谢Redfox的源程序,游戏中的地图数据和角色移动的核心代码基本保持原版,对这部分内容仅作了格式上的调整。
目前只能算是入门级水平,如果游戏中有任何逻辑错误,请大家自行对源代码修改(源代码是:版权没有,翻版不纠!
但请大家尊重Redfor的源码,如要转载,请与原作者联系)-Redfox hereby like to thank the source, in-game map data and the role of mobile code essential to maintain the core of the original, this part of the contents were only format adjustments. The current level can only be regarded as entry-level, if the game has no logic error, please everyone to modify the source code (source code is: there is no copyright infringement is not correct!
