Once everything is inserted, your circuit should look similar to the following:

In this case, we show the circuit connected to a CAN simulator. However,

you could instead have your circuit connected to a DLC in a CAN-enabled

vehicle.

Here we see the circuit connected to Pete Dokter’s VW.

Arduino Code

Download the Library

There’s a really great library available for working with the CAN-Bus shield.

You will need to download this and install it in your Arduino IDE. You can

either search for it in the Arduino Library Manager or download the most

recent version from the GitHub repository.

If you aren’t sure how to install the Arduino library, please take a look at our

tutorial here.

Example Sketches

There are several different example sketches included in the library, each

with different functionality.

1.SparkFun_CAN_Demo - This sketch allows you test the CAN

functionality of the board by itself.

2. SparkFun_ECU_Demo - This sketch runs all hardware on the shield

together, and logs CAN data and GPS data to the SD card, while outputting

data over the serial LCD. You will need to instally the TinyGPS library and

the SD library for this to work.

3.SparkFun_GPS_Demo- This sketch runs through using the GPS

module. You will need to instally the TinyGPS library for this to work.

4.SparkFun_Joystick_Demo - This quick sketch allows you to test the

functionality of the on board joystick.

5.SparkFun_SD_Demo - This sketch allows you to verify and test

functionality of the microSD socket on board. You will need to install the SD

library for this to work.
