- Selectable input modes (DirectInput, DirectInput + Keyboard)
- 17 full re-assignable buttons
- Less than 1 ms of input latency
The default input mode replicates the behavior of a gamepad with 4 hats and 17 buttons. During the development of the StepBOX, we faced across a scenario where in KShootMania buttons 1 2 5 6 can be set as left and right lasers normally but in unnamed-sdvx-clone it requires a real knob.
We get around this problem by implementing a composite-device that behaves both as a gamepad and as a keyboard. In this way, when activating Keyboard Mode some buttons also triggers some ASCII keys:
[1] -> W
[2] -> E
[5] -> O
[6] -> P
- Unplug your StepBOX from USB;
- Hold the button
16(Select) and plug your device again; - The onboard LED should be on indicating the new mode.
Prebuilt uf2 files are available in the Releases section for the following boards and controllers:
Shory Board(not available yet)- Raspberry Pi Pico and other RP2040 boards
Instructions for a Raspberry Pi Pico.
- Download the latest
StepBOX.uf2file from the Releases section for your board (e.g.StepBOX-RaspberryPiPico.uf2for the Raspberry Pi Pico); - Unplug your Pico;
- Hold the BOOTSEL button on the Pico and plug into your computer. A new removable drive named
RPI-RP2should appear in your file explorer; - Drag and drop the
StepBOX.uf2file into the removable drive. This will flash the board. - The board is now running the StepBOX firmware and will appear as a controller on your computer.
