Warnung: RPi Unterstützung sollte als experimentell betrachtet werden.Es kann zu Problemen kommen, wenn GIMX auf dem RPi ausgeführt werden soll.

GIMX can run on many Linux targets, and the the Raspberry Pi is one of them!

Hardware considerations

Use a USB HUB only if there are no ports available on the RPi.
It is highly recommended to use a HUB with an external power supply.

Firmware update

As early firmwares had severe USB issues it is recommended to update the firmware before using GIMX.
Updating the firmware may also be useful if you plan to use a Logitech force feedback wheel (the uhid kernel module was missing in earlier firmwares).
Type the following command:

sudo rpi-update

And don't forget to reboot:

sudo reboot

Tested Rpi firmware:

pi@raspberrypi ~ $ uname -a
Linux raspberrypi 4.1.9+ #819 PREEMPT Thu Oct 1 20:31:26 BST 2015 armv6l

USB adapter using the on-board UART interface

Hardware requirements

The on-board UART runs at 0V/3.3V levels, and the AVR USB board has to run at 5V to operate at 16MHz (running at 3.3V would only allow to operate at 8MHz).
Connecting the RPi and the AVR USB board directly may damage the hardware!
One cheap solution is to use a voltage divider:

• Connect both GNDs
• It's safe to connect the TXD pin of the RPi to the Rx pin of the AVR USB board (the GIMX firmwares configure the Rx pin as an input)
• To connect the Tx pin of the AVR USB board to the RXD pin of the RPi, you'll need to convert the voltage level from 0..5V to 0..3.3V.
  

This can be done with a simple resistive divider:

Vin is the Tx pin of the AVR USB board, Vout is the RXD pin of the RPi, R1=2.2kΩ , R2=3.3kΩ

• Do not connect any other pin!

Sotware adjustments

By default, the RPi sends debug messages on the UART port. To use it for GIMX, we should execute:

sudo raspi-config 

Then select:

"Advanced Options", "Serial", "No", "Finish"

Open the /boot/config.txt with the nano editor:

sudo nano /boot/config.txt

Add the following line at the end of the file:

init_uart_clock=8000000 

Create a symbolic link to make gimx-launcher find the port:

sudo ln -s /dev/ttyAMA0 /dev/ttyUSB0

GIMX installation

sudo apt-get install gdebi
wget http://gimx.fr/download/gimx-raspbian -O gimx.deb
sudo gdebi gimx.deb

If you get a "Dependency is not satisfiable: ..." error message, upgrade Raspbian:

sudo apt-get update && sudo apt-get upgrade

Stop/disable triggerhappy service

Triggerhappy is a daemon that opens every input device for reading, and that consumes a few percent of the CPU time.

It seems a good idea to stop it while running GIMX.

To stop triggerhappy:

sudo service triggerhappy stop

To disable triggerhappy:

sudo update-rc.d triggerhappy disable

Run GIMX

Read the Quick start page to learn how to run GIMX through the GUI.
A good idea is to run GIMX directly from a terminal, without starting a graphical session.
This can be done over the network, using a ssh client.
Ideally, GIMX should be launched without using the Ethernet port (because it is connected on the USB bus).
More details on command line options on this page.

Bluetooth

In a terminal:

gimx -t Sixaxis -c <config file> -b <PS3 bdaddr>

The dongle address has to be changed before running the above commands.

DIY USB adapter

In einem Terminal:

gimx -c <config file> -p /dev/<ttyUSB port>
