| Abstract: | A kind of intelligent adapter between CAN bus network and PC/104 system was developed. The adapter consists of an interface of CAN bus network, a CAN receiver connecting with the interface, a CAN controller, a PC/104 bus-slot, a high speed opt coupler, a microprocessor and a parallel interface circuit. PC/104 system can take charge of transmitting and receiving data without performing maintenance of CAN bus because of using the microprocessor. Thus the system resource can be saved for other tasks. The adapter used parallel communication mode and had high data transmission rate. The drive VxD of the adapter and functional module of the PC/ 104 system were programmed. Debugging shows that the adapter works stably and satisfactorily. |
