基于J1939协议的组合仪表的设计与实现

Design and achievement of combined meter based on J1939 protocols

本文首先介绍了CAN总线和J1939协议,然后重点介绍了基于J1939协议应用AT90CAN32作为微控制器的组合仪表的硬件和软件的实现方法,并且在实际的调试当中,取得了良好的效果,充分证明了方案的可行性。

First, the CAN BUS and J1939 Protocols are introduced in this paper. Then,this paper concentrate on introducing method of hardware and software design of the Combined Meter based on J1939 protocols and use AT90CAN32 as its microcontroller .Finally, it has been made Good results in practical debugging, fully proved the feasibility of the design.
