## Technical details

This controller has two handles (13 power notches and 7+emergency brake notches), a D-Pad and 6 buttons (Select, Start, A, B, C, D). In addition, it provides a simple display, a door lamp and a 3.5 mm jack connector to plug a horn pedal. There are two rumble motors, one in each handle.

Internally, it is a HID device with a vendor-specific class.

### Input

The controller sends reports to the host (PS2) formed by 6 bytes:

Byte 1 | Byte 2 | Byte 3 | Byte 4 | Byte 5 | Byte 6
--- | --- | --- | --- | --- | ---
Brake | Power | Pedal | D-Pad | Buttons | Unused

The values for the brake notch byte are the following.

Released | B1 | B2 | B3 | B4 | B5 | B6 | B7 | Emergency | Transition
--- | --- | --- | --- | --- | --- | --- | --- | --- | ---
0x1C | 0x38 | 0x54 | 0x70 | 0x8B | 0xA7 | 0xC3 | 0xDF | 0xFB | 0xFF

The values for the power notch byte are listed below.

N | P1 | P2 | P3 | P4 | P5 | P6 | P7 | P8 | P9 | P10 | P11 | P12 | P13 | Transition
--- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | ---
0x12 | 0x24 | 0x36 | 0x48 | 0x5A | 0x6C | 0x7E | 0x90 | 0xA2 | 0xB4 | 0xC6 | 0xD7 | 0xE9 | 0xFB | 0xFF

The pedal byte has two possible values depending on the state of the pedal.

Released | Pressed
--- | ---
0xFF | 0x00

The D-pad byte represents the state of the arrow buttons. If two opposite directions are pressed simultaneously, the result is Center unless a third button is pressed.

N | NE | E | SE | S | SW | W | NW | None/Center
--- | --- | --- | --- | --- | --- | --- | --- | ---
0x00 | 0x01 | 0x02 | 0x03 | 0x04 | 0x05 | 0x06 | 0x07 | 0x08

The button byte uses six bits to represent the state of the physical buttons. 0 means that the button is released and 1 that it is pressed. A bitmask can be used to retrieve the buttons.

Button 1 | Button 2 | Button 3 | Button 4 | Button 5 | Button 6
--- | --- | --- | --- | --- | ---
D | C | B | A | SELECT | START

### Output

The controller supports receiving data via a control transfer to update the screen, turn on/off the door lamp and provide rumble. The setup packet is as follows:

bmRequestType | bRequest | wValue | wIndex | wLength
--- | --- | --- | --- | ---
0x40 | 0x09 | 0x0301 | 0x0000 | 0x0008

The data sent to the controller follows the structure below.

Byte 1 | Byte 2 | Byte 3 | Byte 4 | Bytes 5-6 | Bytes 7-8
--- | --- | --- | --- | --- | ---
Left rumble | Right rumble | Door lamp + Limit approach | Speed gauge | Speedometer | ATC limit

- Left/right rumble: 0x00 is Off, 0x01 is On.
- Door lamp: 0x0X is Off, 0x8X is On.
- Limit approach: values between 0xX0 and 0xXA representing the number of LEDs lit above the speedometer. In-game, these mark the 10 km/h right below the speed limit.
- Speed gauge: values between 0x00 and 0x16 representing the number of LEDs lit on the speed gauge. LED #23 cannot be lit. In-game, these mark 15 km/h increments in the current speed, with one lit when speed is 1-15 km/h, two when 16-30 km/h, etc.
- Speedometer: values between 0x0000 and 0x0999 representing the current speed. Values are encoded with BCD 8421 (i.e. 120 km/h should be represented as 0x0120, NOT 0x0078).
- ATC limit: values between 0x0000 and 0x0999 representing the ATC speed limit. Values are encoded with BCD 8421 (i.e. 120 km/h should be represented as 0x0120, NOT 0x0078).

Multi-byte values should be stored in Little Endian.
