本文详细介绍如何使用GAINS节点和我们开发的MAC协议的代码实现无线通讯功能的过程。涉及到avr单片机的编译器winavr，烧写软件avr studio以及avr系列单片机的烧写器，本文介绍如何使用avr studio 和烧写器将winavr编译后产生的hex文件存入单片机flash的过程。这个过程完成以后，就可以组织一个小规模的单跳网络，通过SNAMP后台可以看到网路的可视化效果。

-This paper describes how to use GAINS nodes and MAC protocol, we developed the code to achieve wireless communication process. SCM involves avr compiler winavr, software programmer avr studio, as well as programmer avr series MCU devices, the paper describes how to use avr studio and programmer will winavr compiled hex file generated into single-chip microcomputer flash process. After the completion of this process, we can organize a small-scale single-hop network, the background can be seen through SNAMP network visualization.
