Decision on Parameters by Using SJA1000 to make up CAN Network Intelligent Nods
Xiao Jianwei (No.711 Research in stitute,CSIC Shanghai,2003)
The advantage of CAN bus is simple and reliable, and SJA1000 is selected as the first communication controller to structure a CAN network by its predominant capability. But its application was embarrassed by some factors such as selecting node identifier, calculating the bit rate, etc. This article presents the selecting of parameter, the relationship between bit rate and distance and the way of ascertaining the value of bit time register(BTR) in detail.
