Application of DS80C400 in the embedded intelligent network-bridge Li huiping1 Hanjin1,2 Xueqingjun1 (1. Information Science College, SUST, Qingdao, Shandong 266510, China;. 2.School of Mechanical & Electronic Engineering and Automation, Shanghai University, Shanghai 200072, China;) Abstract: The plan of embedded intelligent network-bridge which takes DS80C400 as the core processor connect the multi channel CAN network to the multi channel Ethernet is proposed in the article. The connection between DS80C400 MII and exterior physical equipment is given; the configuration method of JAVAKIT under the platform in WINDOWS is elaborated. The exploitation frame and the programming method based on TINI OS are planned. Developing embedded system with the DS80C400 micro controller may conveniently develop the network application system, greatly enhances the development efficiency.
