| Abstract: | The interface design of USB and CAN is based on CY7C68013A MCU supporting USB2.0 protocol. Its firmware deals with the request of PC, and completes the USB communication with PC. The firmware controls the SJA1000 and complete the sending and receiving of CAN frame. The AD bus of SJA1000 connected with the I/O of CY7C68013A. And the timing of SJA1000 is simulated from I/O by soft ware. |
