7. CAN Pins

4 CAN lines are broken out to allow you direct access to the raw CAN data

coming off of the DB9 connector. These pins are:

•5V

•GND

• CAN H (CAN HIGH)

• CAN L (CAN LOW)

Again, this data is raw coming off of the CAN-Bus. It has not been filtered

through the MCP2515 or the MCP2551 ICs.

Communication Methods

Because of all of the different hardware features on the shield, there are a

couple different communication methods used.

• SPI - The MCP2515 IC and the microSD slot both communicate with

• Analog In - The joystick is connected to pins A1-A5 on the Arduino.

Each direction of the joystick has its own analog input.

• Software Serial/UART - The LCD and GPS both communicate over

Hardware Hookup

Solder Connectors

To get your CAN-Bus shield hooked up, solder on the Arduino Stackable

Headers.

You can use the RedBoard to hold the headers in place while soldering

them to the shield.

Once those are soldered, consider how you want to connect your LCD

screen. You can use either male or female headers with 0.1" spacing, or

the JST connector. Solder your interface choice onto the shield at this time

as well.
