| Abstract: | For the difficult situation in upgrading application programs in the nodes in a controller area network (CAN) system, this paper raises a scheme which is based on CAN bus and ISO14230 diagnostic protocol.It takes advantage of the integrated function blocks of STM32F103VET6, which affords the Cortex M3 kernel, and the in application programming (IAP) technology is well used to design and implement the online updgrade scheme. The scheme provides high reliability and good stability,and the design of the remote online updgrade scheme in other embedded systems can also be easily used. |
