Arduboy homemade package

Arduino IDE board package for Arduboy and homemade versions with the following advantages:

  • Single install
  • Includes all Arduboy libraries with support for alternate displays and wiring
  • Includes Arduboy optimized Arduino core with extra features and space savings
  • Cathy3K bootloader support

To install the package:

  • Start Arduino IDE and press CTRL + comma to select properties.
  • Copy and paste the URL below in Additional Boards Manager URLs: text box and click on OK
https://raw.githubusercontent.com/MrBlinky/Arduboy-homemade-package/master/package_arduboy_homemade_index.json

preferences After this:

  • Go to Tools > Boards > Board manager
  • In the text box type homemade or Arduboy homemade
  • Click on the Arduboy Homemade package and click the Install button.

You can now select Arduboy, Arduboy DevKit and Homemade Arduboy boards from the Tools menu.

Numbers before the portnames are Arduino assigned pin numbers.

(*) Pro Micro alternate wiring pins:

  • PORTD3 OLED CS
  • PORTD1 OLED RST
  • PORTD7 SPEAKER 2
  • PORTD0 RGB LED GREEN

(**) speaker pin 2 output is connected to speaker pin 1 on DevKit hardware. To prevent the IO pins from possible damage, speaker pin 2 should NOT be configured as an output.

(***) Future Flash cart support:

  • 0 PORTD2 Future flash cart chip select
  • 14 PORTB3 flash cart data in (MISO)

(future) expansion connector

An expansion connector can be added to modified or Homemade Arduboy in the form of a 12 pin female header with 0.1"pitch. which can be used for:

  • ICSP header for easy in circuit programming (updating bootloader)
  • flash cart slot
  • SD card adapter
  • infrared communications
  • multiplayer link
  • sensors
