6.SparkFun_SerialLCD_Demo - A quick sketch to make sure your serial

LCD screen is functioning properly.

For our example, we are going to run through the ECU_Demo sketch, but

feel free to use or modify the other sketches. If you decided to not plug in

the microSD card, GPS unit and LCD screen, you should instead run the

CAN_Demo.

ECU_Demo

This sketch shows off the basic functionality of each part of the shield.

Once you’ve installed the library, open up Arduino and upload this code to

your RedBoard.

Check through the comments in the code for details of what each section

does, but the general flow of the sketch is as follows:

1. The Arduino initializes the pins, variables, and baud rates for the

GPS, LCD, uSD card, and CAN-Bus.

2. In the setup loop, each device is started, and verified that everything

is connected as it should. Both the CAN-Bus and uSD card will print

either success or failure messages to the LCD screen.

3. The shield will wait for the user to click the joystick to begin collecting

data off of the GPS module and the CAN-Bus.

4. Once the user has clicked to begin logging, the CAN-Bus will poll for

the engine RPM, and will write the latitude, longitude, and GPS

speed. A message that the unit is logging will appear on the LCD

screen, and the actual engine RPM will be printed to the Serial

monitor. The data collected is written to the uSD card.

5. Each loop, the code checks if the user has clicked the joystick. If so,

the unit stops logging.

This example sketch works with the CAN­Bus shield from S

parkFun Electronics.

If you’ve uncommented the lines for serial debugging, you should see

something like this:
