GIMX stands for Game Input MultipleXer or Game Input MatriX. The purpose of this software is to control a video game console with a computer (e.g. a PC or a Raspberry Pi). It works with the PS3, the Xbox 360, and the PS4.
It operates:
¤ over bluetooth: works with Linux (PS3, PS4) only. A compatible bluetooth dongle is required.
¤ over usb: works with Linux and Windows (PS3, PS4, 360). A USB adapter is required.
The application gets data from the peripherals (mice, keyboards and joysticks) and sends controls to the game console over bluetooth or usb. Other controls such as gesture or voice are possible through the use of external software that emulate peripherals.

GIMX PS4 support – status 10 – DIY USB adpater

GIMX can now control a PS4 over USB in both Linux and Windows! I will release in the next days a new firmware for the DIY USB adapter and a new GIMX software.

The connection diagram is as follow:

DS4 -- PC -- USB to UART adapter -- AVR USB board -- PS4

The DIY USB adapter is unchanged: it is composed of a AVR USB board and a USB to UART adapter.

The AVR USB board (such as a Teensy 2.00) enumerates similarly to a Hori Pad 4 FPS.

When the AVR USB board receives a control request from the PS4 that is part of the authentication scheme, this request is forwarded to the USB to UART adapter, then to the PC, and finally to the DS4. The reply from the DS4 takes the opposite path.

As for the 360, authentication data goes in both direction, but for the PS4 it is periodic. GIMX processes authentication data from the serial port and from the DS4 asynchronously. This makes data forwarding fast and efficient.

The drawback compared to the bluetooth solution is that it’s not possible to emulate touchpad & motion sensing controls, which are required in some games (mostly in PS4 exclusive ones). The other adapters (XIM/Titan/VenomX) have these limitations, and there no work-around yet. At least the USB solution is usable in most cross-platform games.

GIMX PS4 support – status 9

I pushed gimx-config & gimx-fpsconfig updates in the git repository.

In gimx-config, there is a new “Type” menu that allows to change the controller type. Setting the right controller type allows to display controller-specific axis and button names.

I will now work on merging gimx-serial and gimx-bluetooth in a unified launcher that will also support the PS4.

GIMX PS4 support – status 8

I pushed touchpad support in the git repository.
People that already cloned the source can run the following commands to update GIMX:

cd GIMX
git pull
make clean
make
sudo make install

I wrote a configuration for KillZone Shadow Fall that showcases this touchpad support. It can be downloaded via gimx-serial or gimx-bluetooth, using the “Help>Get Configs” menu (the file is named PS4_KillZoneShadowFall.xml). Key ‘f’ controls finger presence and the mouse axes control finger coordinates.

I will now work on updating the GUIs.
