Arduino CAN-Bus OBDII demo

arduino, , , ,

This movie is a demo of the Arduino CAN-Bus shield. It is connected to a car via the OBDII port. The demo give a real time reading of RPM, road speed, engine temperature and throttle position. It uses the Microchip MCP2515 CAN controller with MCP2551 transceiver.

    Hi,

    I´m trying to run the CAN-Bus ECU Reader demo sketch from your site.

    It starts and prints “CAN Init ok”, but than it freezes. I´ve done some debugging and got the line where it breaks. It´s this line:

    mcp2515_check_message()

    inside the Canbus.cpp

    I really don´t know why this is happen and how to fixe it. The CAN-board was connected to an 2010 Volkswagon.
    Any hints in the right direction?

    greetings Sunny

    @gunnarMyTube For any commercial deployment of a solution you typically make your own custom board containing the circuits needed from Arduino and the shield. Open source licensing apply if you deploy Arduino based code and hw designs.

    @PabloDiazLP This “shield” board plugs on top of a regular Arduino processor board. You upload the code (“sketch” in Arduino lingo) to the processor board that access the hardware on the shield board to accomplish the CAN/ODB interface access, LED display, SD card and GPS access. Code is open source so you can extend it any way desired. There is also a small joystick on the shield for menu navigation (up down L R + push)

    I got those parts from Pang and will begin experimenting. Lots of potential, think of all the cars manufactured since around 1995 with ODB2 ports.
