摘要
CAN总线是几种最有前途的现场总线之一。但是CAN总线开发需要一定的技术基础,如何在较短的时间内开发出一套可靠性高、实时性好的CAN系统,成为众多电子开发人员十分关注的问题。采用AVR单片机作为微处理器,设计一个用于气体监测的CAN总线网络,给出了基本CAN节点的硬件原理图和程序流程图,阐述CAN总线调试过程一些细节和经验。
CAN bus is a promising fieldbus,it requires some technology knowledge to design a CAN bus application system. So,how to develop a CAN bus provided with excellent reliability becomes a very hot problem which many electronic developers care. A design method of gas monitoring system is presented in this thesis. AVR single chip is used as the microprocessor and CAN bus is adopted to construct the communication network. For other people reference, the author detailedly provids the hardware interface and software flow chart of basic CAN junction. The details and the author＇s experience in the debugging of CAN bus are also introduced.
