Library for abstracting game-controller input into a stable, RetroPad‑inspired interface. It provides a fast, bitfield‑based state model, parsers for analog sources, and mappers for bridging targets.

Designed for embedded systems, it minimizes RAM use and supports deterministic, task‑based updates.

• Read only API for controller state.
• Fast state copy, for double buffering.
• Bit field button states, optimized for low RAM and fast copy.
• ControllerParser to extract action events or digital values from an analog source
  • Button Up/Down
  • Joystick Up/Down/Left/Right
  • Axis Up/Down

• Inherits from VirtualPad
• Write/Read API for controller state
• Support functions to translate "analog" values (Joysticks and Sliders)

• Arduino ADC+IO simple controller.
• Nintendo64/GameCube controllers (JoybusOverUart https://github.com/GitMoDu/JoybusOverUart)
• Mega Drive Controller Pad (74HC151)

Task features depend on Task Scheduler https://github.com/arkhipenko/TaskScheduler

• ControllerMap: fixed period, template mapper from source to VirtualPad
• ControllerDispatch: fixed period notifier for dispatch interface
• ControllerToX360: fixed period mapper from IInputController to USB-XBox360 controller

• Source Controller to VirtualPad

  • Arduino ADC+IO
  • Nintendo64/GameCube

• Dispatch listener with IInputControllerDispatch interface

• Button Actions

  • Single action for each button event
  • Actions expire after each parse step
  • Joystick digitalization, with hysteresis

• Nintendo64/GameCube controllers Passthrough to XBox360

  • STM32Duino only https://github.com/rogerclarkmelbourne/Arduino_STM32
  • USB-XBox360 https://github.com/arpruss/USBComposite_stm32f1
