| Abstract: | The design of CAN interface based on S3C2410 hardware platform for multi-axis embedded NC system was described. The embedded NC system structure based on CAN was presented. The key design techniques of CAN interface were discussed. The priority of the transmitting message was set in terms of the identification code of CAN frames. A priority algorithm was devised to improve the communication performance. The applicability of the CAN interface was verified. |
