Driver-Display

Code to display data on the 2 4x20 LCD displays from the car to the driver.

Upload Instructions (Linux)

• Ensure you have Arduino Cli installed.
• Update local cache:

  arduino-cli core update-index
  

• Add the Liquid Crystal Library that we use:

  arduino-cli lib install "LiquidCrystal I2C"
  

• The Wire library should be included so you don't need to install it separately.
• Clone the repo and navigate to the USEV-Driver-Display directory.

Compilation Only

If you only want to compile the code to check that it works, not upload it:

• Install Arduino boards:

  arduino-cli core install arduino:avr
  

• Locate the FQBN of the board from the list that you wish to compile for:

  arduino-cli board listall
  

• We are using an Arduino Uno, so we use arduino:avr:uno
• Compile the code, here we are using an Arduino Uno:

  arduino-cli compile -b arduino:avr:uno display_4x20 --build-path build
  

• This compiles the code for an Arduino Uno, storing the build in the build folder.

Uploading

If you want to compile and upload the code to a board:

• Connect the Arduino to your computer
• List the available boards and where they are conected using:

  arduino-cli board list
  

  From this, note the FQBN and Port
• Using the FQBN, install the core for your board:

  arduino-cli core install FQBN
  

  where FQBN is your board type, eg. arduino:avr:uno
• Compile the code, replacing FQBN with your board type:

  arduino-cli compile -b FQBN display_4x20
  

• Finally, compile and upload your code using:

  arduino-cli upload -p Port -b FQBN display_4x20
  

  Where Port and FQBN are replaced with the values from earlier.
  Note: If you get a permission error upon upload, such as Error opening serial port..., you may need to change permissions. See the "Please Read" section of this page.

• To upload a new version, simply run the last 2 steps again

If you don't have linux or don't want to use the cli, you may use the Arduino IDE instead if you wish
