Abstract: A CAN bus interface module was designed to connect the other subcontrol systems to realize the realtime, reliable performance requirement of the high speed airjet weaving machine. The hardware platform was mainly built using embedded microprocessor s3c2440A based on ARM920T kernel of Samsung company and CAN bus controller MCP2515 of Microchip. The software designing was implemented in the Windows CE operating system, including of driver module selection, stream interface functions realization, interrupt handling etc.. The test results show that the design meets the requirements of data transmission speed and reliability.
Key words: ARM920T; Win CE 5.0; embedded system; CAN driver
