ExamplesĮxample implementation of CanHacker (lawicel) protocol based device: įor more information, please refer to wiki page. UlData represents the content of the mask of filter. false means it's a mask or filter for a standard frame. RXF num represents one of six acceptance filters registers from MCP2515::RXF0 to MCP2515::RXF5Įxt represents the status of the frame. MASK mask represents one of two mask MCP2515::MASK0 or MCP2515::MASK1 MCP2515::ERROR setFilter( const RXF num, const bool ext, const uint32_t ulData) MCP2515::ERROR setFilterMask( const MASK mask, const bool ext, const uint32_t ulData) The available modes are listed as follows: To create connection with MCP2515 provide pin number where SPI CS is connected (10 by default), baudrate and mode

Restart the Arduino IDE to see the new "mcp2515" library with examples.

From the Arduino IDE: Sketch -> Include Library.

TJA1055 Fault-tolerant low speed CAN Transceiver.

MCP2562 High-speed CAN Transceiver with Standby Mode and VIO Pin - an updated tranceiver since the MCP2551 (requires different wiring, read datasheet for example, also here).

MCP2551 High-speed CAN Transceiver - pictured above, however "not recommended for new designs".MCP2515 Stand-Alone CAN Controller with SPI Interface.

If you want to make your own CAN board for under $10, you can achieve that with something like this: The following code samples uses the CAN-BUS Shield, wired up as shown: Two receive buffers with prioritized message storage.Standard (11 bit) and extended (29 bit) data and remote frames.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. This CAN-BUS Shield gives your Arduino/Seeeduino CAN-BUS capibility.

It is commonly found on modern machine tools and as an automotive diagnostic bus. CAN-BUS is a common industrial bus because of its long travel distance, medium communication speed and high reliability.
