说明：  机器人程序,Atmega8是前后传感器小板上的芯片的程序（前后都有，但用的是同一个程序），它将数据处理后通过异步串口（uart）传给主芯片。*_project是完整的工程文件，很多文件是编译器自动生成的，只有.c和.h的文件是自己写的，我把它们单独放在*_useful里了。提示一下：1. config.h中定义了所有的引用（include），其他xxx.h中引用config.h，相当于引用了所有的需要的xxx.h。 2. 每一个xxx.c文件都和一个同名的xxx.h文件对应（main.c和config.h除外），xxx.h引用config.h并定义所有xxx.c中的函数，以便yyy.c能调用xxx.c中的函数。
(Robot program, Atmega8 is a small plate of chips before and after the sensor program (after all, but use the same program), it will post data processing asynchronous serial (uart) to the primary chip.* _project Is a complete project file, many files are automatically generated compiler only. C and. H files are write, I put them in a single place* _useful. Reminder: 1. Config.h defines all of the references (include), the other xxx.h reference config.h, the equivalent of all the necessary references xxx.h. Two. Xxx.c each file and a file corresponding to the same name xxx.h (main.c and config.h exception), xxx.h reference to config.h and define the function of all xxx.c to yyy.c can call xxx.c the function.)
