Introduction 
TheCAN-BUSis a common industrial bus because of its long travel distance, medium 
communication speed and high reliability. It is commonly found on modern machine tools 
and as an automotive diagnostic bus. This CAN-BUS Shield adopts MCP2515 CAN Bus 
controller with SPI interface and MCP2551 CAN transceiver to give your 
Arduino/Seeeduino CAN-BUS capibility. With an OBD-II converter cable added on and 
the OBD-II library imported, you are ready to build an onboard diagnostic device or data 
logger.

1. Download the CAN-BUS Source code and release it in the libraries file in the Arduino1.0 program.: ..\arduino-1.0\libraries. 2. Open the Arduino-1.0, and you will find two examples: "receive" and "send". Open both of them, you should get two programming windows now File:CAN-USB-M.jpg 3. Upload two examples to two boards separately. Choose the board via the path: Tools ->Serial Port-->COMX. Note down which board is assigned as a "send" node and which board is assigned as a "receive" node. 4.
