2" ST7789 TFT display module for a Boba Fett costume

Cosplay: Fett Display

Display module for a Boba Fett costume. Uses a 2" TFT display instead of the traditional segment display/LED bar graph combination. The goal behind this choice was a thinner electronics package and the ability to make some customizations not afforded by a 7-segment display.

Components

• Adafruit FLORA v3 (ATmega32u4 Chip)
• Adafruit 2.0" 320x240 Color IPS TFT Display (ST7789 TFT Driver)

Required Libraries

• Adafruit GFX Library
• Adafruit BusIO
• Adafruit ST7735 and ST7789 Library

Development

1. Install arduino-cli if it is not yet installed.
2. Create configuration file if you have not yet created one:

   arduino-cli config init
   

3. Install board support for the Adafruit FLORA:

   arduino-cli config add board_manager.additional_urls https://adafruit.github.io/arduino-board-index/package_adafruit_index.json
   arduino-cli core update-index
   arduino-cli core install adafruit:avr
   

4. Add dependent libraries:

   arduino-cli lib update-index
   arduino-cli lib install "Adafruit GFX Library"
   arduino-cli lib install "Adafruit BusIO"
   arduino-cli lib install "Adafruit ST7735 and ST7789 Library"
   

Compile

The sketch can be compiled with make, assuming the steps in development have been followed.

make clean      # Delete build files
make            # Build sketch
make install    # Upload sketch to Adafruit FLORA
