CAN – BUS is a common BUS industry, because of its support for a long distance, medium speed and high

reliability of communication.It is often found in modern machine tools and Automotive diagnostic bus.The

CAN – BUS expansion board adopt the CAN BUS controller of MCP2515, SPI interface and MCP2551 CAN

transceiver, communicate with your Arduino. With OBD II conversion line and the improvement of the OBD

II – library, you can create an on-board diagnosis device or data recorder.

The CAN transfer rate is as high as 1 Mb/s SPI interface transmission rate is as high as 10 MHz Standard (11

bite ) and (29 bite) data transmission. The two have the priority to accept the cache information

9 needles industry standard sub – D interface

Two LED indicators

Specification

voltage: 4.8~5.2V

Size:  68x53mm

1. Download the CAN_BUS_Shield, upzip it to this path:..arduino-1.0libraries.

2. Open the ”receive” and “send”,you need to open two Arduino IDE to open them.

[Open_CAN_BUS_examples]

3. Respectively download to two Arduino, record which expansion board is the ‘send’ and which is ‘receive” board.

4. Open the serial software tool and set the baud rate to 115200, you can see the result as the following picture( respectively are the output information of receive port (left) and send port (right)).
