摘要
为解决CAN总线系统节点应用程序更新问题,本文利用节点微控制器LPC2119集成的功能模块和IAP技术,设计与实现了在线更新机制。该机制使用、维护方便,可靠性高,扩展性好,对其他嵌入式应用软件的升级有借鉴作用。
This paper proposes a mechanism for updating application programs in the nodes in a CAN bus system,which solves the inconvenience problem in updating the application programs in the CAN nodes. Advantages of the integrated function blocks of LPC2119 are taken,and the In-Application Programming （IAP） technology is used to design and implement the online update mechanism. The mechanism has high reliability and excellent expansibility. It is easy-to-use and easy-tomaintain, and can also be used in the design of the on-line update mechanisms in other embedded systems.
