硬盘接口线的定义，作单片机的

51单片机的模拟I2C总线接口函数，附带完整注释。-51 microcontroller simulation I2C bus interface function, fringe integrity Notes.

网上看到的一个避障小车的程序。该程序是avr单片机上应用的。-Online to see a car obstacle avoidance procedures. The procedure is applied Singlechip avr.

这个是我今天用Keil_C51写的关于MAX5417的底层函数，微控制器可以用其他的（我是用51的，其他的话，只要修改一下头文件就可以了），上层软件只要调用Write_MAX5417()这个函数就可以了，代码简洁，层次分明，注释也不少，非常适合新手学习或者是直接拿来为自己的上层软件服务。-This is what I write today with Keil_C51 on the bottom of MAX5417 function, microcontroller can use the other (I am using the 51 other words, as long as the modified header file you can), and the upper software as long as the call Write_MAX5417 () this function it, the code is simple and structured notes are also many, very suitable for novices to learn, or is directly used for their top software services.
