Abstract :
This paper propose a scheme of CAN-Bus universal interface module base on USB, The scheme uses USB chip CH375, CAN chip SJA1000, and uses MSP430F449 as control unit to complete USB, CAN interface control, as well as between the data processing and others. This paper also introduces software process and PC application program. In order to record the transmission time interval of the CAN information frame, each CAN message is added the timestamp, the timestamp precision can reach 0.1ms. After tests show that the software and hardware of the design is reasonable, and work is reliable. The interface can be applied to 1553B bus system development, testing and simulation experiment.
