This is Arduino code for making a gamepad using an ATmega32U4- based board.

Tested with an Arduino Pro Micro clone, works out of the box with at least PC (and supposedly PS3).

This fork is made primarily for This not-so-slimbox 3d print project, which you should check out ;)

• Blazing fast!
  • On Arduino Pro Micro 8Mhz @3.3V entire update loop takes only 230 μs ie 0.230 ms.
  • Note: you will most likely be bottlenecked by USB update rate (max. 1000 updates a second, ie fastest update time possible is 1ms)
• OOP style: reliable and trivial to extend
  • Like the functionality but not the imlementation? Just inherit and override!
• Per-button debouncing with possibility for per-button custom timings
  • Just edit respective DEBOUNCE_BUT_XXX definitions with whatever timings you want!
• S.O.C.D. (Simultanious Opposing Cordinal Directions) cleaning strategies:
  • TournamentLegal (default):
    • left + right = neutral
    • up + down = up
  • AllNeutral:
    • left + right = neutral
    • up + down = neutral
  • LastInputPriority
    • left + right = right
    • right + left = left
    • up + down = down
    • down + up = up
  • None:
    • No cleaning
  • Possibility to add your own as simple or as complex as you'd like!

• D-pad mode switch to make it act as left stick
• Switching of S.O.C.D. strategy on the fly

• ATmega32U4- based board (mine was a Arduino Pro Micro clone)
• Arduino IDE or Platform.io plugin for VSCode

• For Arduino IDE:
  • rename main.cpp into main.ino and flash
• For Platform.io:
  • Open directory using Platform.io plugin and flash

Should compile in about 2 seconds with no errors

• By default is TournamentLegal (resets on every reconnection)
• To cycle between types press buttons defined by SOCD_STRATEGY_CYCLE_BUTTONS
  • PS + Start by default
  • Order of key presses doesn't matter
• To change button combination for SOCD type cycling:
  • Navigate to line 69 that says #define SOCD_STRATEGY_CYCLE_BUTTONS &PS, &Start
  • List the buttons you'd like instead in similar fasion (see comment in code for more info)
    • Example new line 69: #define SOCD_STRATEGY_CYCLE_BUTTONS &Select, &Start

Pull requests are welcome. For major changes, please open an issue first to discuss what you would like to change.
