By applying the protocols of CAN2.0B and SAE J1939, with ARM Cortex~(TM)-M3-based high-per-formance MCU LM3S8962 as hardware core, a scheme of vehicle digital instrument system is designed. The combi-nation of the CAN bus transceiver CTM1060T and the CAN controller module integrated in LM3S8962 make the ve-hicle digital instrument a node of CAN bus in the vehicle body so that the function of receiving and transmitting the signals on CAN bus is implemented. The display function of meter needle is fulfilled by the permanent magnet step-ping motor MR1107 driven by the driving chip STI6606. Finally the flow chart of CAN data receiving procedure is given and the software for CAN message transmitting and receiving is designed.
