使用单片机进行按键操作，适合初学者学习。简单演示。-using SCM for buttons, for beginners to learn. A simple demonstration.

硬盘控制电路以及原程序Demo,知识是属于全人类的。能将自己的成果无条件与人共享是伟大和受人尊敬的，同时也是一件幸福的事。 由于我想得到幸福和受人尊敬，所以我也开放我的工作成果。（其实也不算什么工作成果，匆匆忙忙用了一晚写的，见笑了。 在此感谢邵春伟同志，我在研究ata协议的时候参考了他写的程序） -drive control circuit and the original procedure Demo, knowledge is the whole of mankind. The results can unconditionally with the people sharing is great and respected, but also a happy thing. I want happiness and well respected, so I open my work. (What is not a work haste spent a night writing, a laughing stock. This would SHAO Chun-wai comrades, I studied ATA agreement for the reference to the writing process)

8253的初始化程序举例: 例1：选择2号计数器，工作在3方式，计数初值为533H（2个字节），采用二进制计数。其初始化程序段为 MOV DX，307H ；命令口 MOV AL，10110110B ；2号计数器的初始化命 令字 OUT DX，AL ；写入命令寄存器 MOV DX，306H ；2号计数器数据口 MOV AX，533H ；计数初值 OUT DX，AL ；选送低字节到2号计数器 MOV AL，AH ；取高字节送AL OUT DX，AL ；后送高字节到2号计数器 -8253 initialization procedures examples : Example 1 : Select counters on the 2nd, in three ways. Counting for the initial 533H (2 bytes), a binary counting. Initialization of its procedures for MOV DX, 307H; I ordered MOV AL, 10110110B; on the 2nd Counter initialize command word OUT DX, AL; write commands Register MOV DX, 306H; data on the 2nd Counter I MOV AX, 533H; Counting initial OUT DX, AL; low-byte sent to the 2nd Counter MOV AL, AH; With a high-byte send AL OUT DX, AL; evacuations high byte counter to the 2nd
