| Abstract: | The design of a CAN bus commutator base on USB was put forward. The paper mainly discussed the use of PDIUSBD12, CAN Bus interface chip SJA1000 and the interface circuit with AVR, and the method that singlechip communicated with PC by USB was also included. The hardware structure, design of the software programe and the notices were explained in details. This design can make protocol by itself and have the ability of amortizing data. The result indicates that the design is feasible. |
