| Abstract: | CAN-bus technology is widely used in the application of embedded operation system. Although there are many kinds of CAN-bus controlling chips, corresponding deriver still needs to be designed in order to expand CAN-bus device in the embedded operation system. In this paper, to meet the demands of technical characteristics of CAN-bus, a hardware design for expanding CAN-bus device based on S3C2410 was accom- plished, which combined the advantages of the embedded Linux operation system with the plentiful resources on S3C2410. The development procedure and design skill of CAN-bus driver are also introduced and details of implementation of CAN-bus driver are described in detail. |
