Abstract: CAN driver is implemented for optical-electronic stabilization and tracking platform, to advance the communication between devices on CAN bus. The mechanism of standard device driver and the model of CAN bus communication in Linux was analyzed firstly. Then the hardware design for CAN bus communication was presented in optical-electronic stabilization and tracking platform. Lastly, the driver for CAN controller MCP2510 with SPI was implemented.
Key words:Linux; CAN bus; O-E stabilization and tracking platform; device driver; serial peripheral interface
