CAN　bus　(Controller　Area　Network),　is　one　of　the　most　widely　used　field　buses　of　world.　This　article　aims　to　explore　that　how　to　control　MCP2510　CAN　bus　controller　to　send　and　receive　data　basing　on　s3c2440　of　Samsung.　In　the　circuit,　this　design　adopts　the　MCP2510　CAN　bus　controller　chip　to　expand　s3c2440　interfaces,　hardware　contains　s3c2440　chip-based　development　board　and　the　MCP2510　CAN　bus　controller,　the　software　mainly　based　on　ARM　Linux.　This　paper　describes　the　hardware　interface　design,　designs　the　CAN　bus　device　driver　base　on　CAN　bus　protocol　and　the　characteristics　of　MCP2510　controller,　analyses　the　design　method　which　adopts　driver　to　control　the　corresponding　circuit.　The　whole　system　has　been　tested　on　board　and　meets　the　design　goal.　©　2010　IEEE.
