这个是一个可以实现3~6KM距离通讯的程序,实现过程都已经详细注释 硬件采用ADC得到原始数据 然后根据线路得编码情况得到数据
而且针对多节点 带了一个自适应的算法 这样就可以在总线上任意两个终端通讯-Can realize this is a distance of 3 ~ 6KM communications procedures, the realization of the process have been detailed notes ADC hardware used to be the raw data was then coded according to the situation of lines of data and for multi-node with an adaptive algorithm can then be in the bus on any two terminal communications
