Arduino CAN-Bus OBDII demo

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.

There is a new version of the sketch at:

You need to install the SD card library from Adafruit first.

Check your car's OBDII connector to see if pin 6 and 14 is wired up. It is then most likely it has CAN.

It is Kia Cee'd.

Hi,

I have got one of these sheilds and have had nothing but problems with it and the sample codes supplied. Even the simplest joystick demo code doesnt run properly, which is leading me to believe that my board is faulty.

However, i am very interested in whether ANYONE as got this product to work.

Please let me know.

@Alexywhite13 Have you tried v3 of the demo sketch?

Hello

I am trying to figure out where the defaults.h, mcp2515_defs.h, global.h, and mcp2515.h are located in your example ecu_reader_logger code? Do these headers need to be included in the code for the ecu_reader_logger to work? I'd appreciate any help. Please let me know.

do you have to request rpm data, or is it appearing in CAN anyway?

Very cool - I'm just getting into the whole Arduino and CANbus deal an have some great ideas for my car. This is the first I've heard that there is a CANbus sheild available. Gotta check it out! Thanks so much for posting this!

@SKPangElectronics , I was only aware of a second version. Can you give me a link to the third version of the sketch?

Thanks for the reply.

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
