Helldivers 2 Strategem Controller

Overview

Call in strategems in Helldivers 2 using a keypad and an arduino with USB capabilities.

Schematic

I've included a Hardware Schematic.fzz for Fritzing.

Common Configuration Steps

There are two variables that will likely need to be configured by the user:

• The keymap const in the main sketch .ino file, which maps the buttons on the keypad to in-game strategems by setting StrategemTypes which can be found in Strategem.h

• The USE_ARROW_KEYS flag, as many players (including myself) have rebound the default wasd to call in strategems to the arrow keys.

Advanced Configuration Steps

Depending on how you wired the arduino to the keypad, you may have to change the values for ROW_PINS and COL_PINS.

If your game isn't registering the keypresses from the Arduino (usually due to lag,) you may have to set the KEYPRESS_TIME const in Strategem.h yourself.
