微机接口课程设计,doc格式。通过这次课程设计使我充分理解了8253和8255两个芯片的工作原理，知道了音乐发声器的硬件和软件的实现过程，并且通过自己动手编写的程序来控制音乐发器的工作，我感到非常有成就感，也锻炼了我的编程能力。-Computer Interface curriculum design, doc format. Through this curriculum design so that I fully understand the 8253 and 8255 the two chips working principle, know the music audible signal device hardware and software realization of the process, and through their own written procedures to control the musical Hair, I is very rewarding, but also exercise my programming ability.
