Supports PlayStation (PS5, PS4), Xbox (Series, One, 360), Nintendo Switch, and generic USB/Bluetooth gamepads.

Connect a controller via USB or Bluetooth and press any button. Visualizes button presses, analog trigger pressure (0.000 to 1.000), analog stick coordinates, stick drift, circularity error, polling rate (Hz), and rumble motors.
