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)

如何解决由于人不在家，所晾衣服被雨水淋湿的问题呢？作者利用义隆单片机EM78447A芯片设计出一种智能晾衣架，它能够自动识别晴天和雨天，智能地为我们服务-How to address people not at home because of the rain soaked clothes were hanging out the problem? The author uses Elan EM78447A single-chip intelligent chip design a drying rack, it can automatically identify the sunny and rainy days, smart for our Service
