| Abstract: | In order to solve the communication problems between CAN-bus system and host PC, a master node is needed to design as conversion interface to achieve CAN date transfer to UART （late and UART date transfer to USB （late. MC9SI2XS256 chip and CP2101 chip were selected to design the master node. The functions of MC9SI2XS256 ehip and CP2101 （：hip were introdueed. The USB to UART serial transmission module and CAN bus transmission module were designed. It is proved the master node design is feasible through debug. |
