### TCPP-20014
No details are available regarding internal functioning.
This controller has two handles (4 power notches and an analogue brake handle with three areas), a D-Pad and seven buttons (Select, Start, Horn, Announce, Camera, Left doors, Right doors). In addition, it provides a 3.5 mm jack connector to plug a horn pedal.
Internally, it is a HID device with a vendor-specific class.

#### Input
The controller sends reports to the host (PS2) formed by 8 bytes:
| Byte 1 | Byte 2 | Byte 3 | Byte 4 | Byte 5 -| Bytes 6-8 |
|:------:|:------:|:------:|:------:|:-------:|:---------:|
| Brake | Power | Pedal | D-Pad | Buttons | Unused |
Unlike traditional controllers, the brake handle is analogue and the brake byte reflects the position of the handle precisely. There are three areas with the ranges listed below.
| Reduce pressure | Keep pressure | Increase pressure |
|:---------------:|:-------------:|:-----------------:|
| 0x24-0x64 | 0x65-0x89 | 0x8A-0xD7 |
The values for the power notch byte are listed below.
| N | P1 | P2 | P3 | P4 | Transition |
|:----:|:----:|:----:|:----:|:----:|:----------:|
| 0x00 | 0x3C | 0x78 | 0xB4 | 0xF0 | 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 seven 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 | Button 7 |
|:--------:|:--------:|:--------:|:-----------:|:----------:|:--------:|:--------:|
| Horn | Announce | Camera | Right doors | Left doors | SELECT | START |
