UnoJoy! allows you to easily turn an Arduino Uno (or Mega or Leonardo) into a PS3-compatible USB game controller
Hi there! Welcome to using UnoJoy!
UnoJoy lets you use a plain, unmodified Arduino Uno
to create native USB joysticks. It is a three-part system:
Drivers - Needed to re-flash the Arduino's USB communication chip
Software - The UnoJoy library for Arduino
Firmware - Code to load onto Arduino's USB communication chip
In order to make UnoJoy work, you'll need to take care of
all three parts. We're here to make that process as easy as
possible.
Drivers
=======
In the UnoJoy directory, there are installer files for the drivers
you'll need for the DFU bootloader. Choose the correct one for your OS:
WindowsUnoJoyDriverInstaller.exe
LionUnoJoyDrivers.pkg
SnowLeopardUnoJoyDrivers.pkg
On Windows, you'll also need to download and install Atmel's FLIP tool:
https://www.microchip.com/developmenttools/ProductDetails/flip
On Linux you'll need to install dfu-programmer. you can get it by typing to your terminal:
sudo apt-get install dfu-programmer
or
sudo aptitude install dfu-programmer
depending on your distribution.
You can also build it from source: https://github.com/dfu-programmer/dfu-programmer
You also have to make the flashing script runnable by typing:
chmod +x TurnIntoAJoystick.sh
into your terminal when in UnoJoy directory.
Software
========
To get started, first, go to the UnoJoyArduinoSample
folder. Open up UnoJoyArduinoSample and upload that code
to your Arduino.
Next, test to make sure that it's working, we have a Processing
sketch to test your controller without having to cycle through
the process of going reflashing the firmware back and forth.
Go to https://processing.org/ to download and install Processing.
Then you can run the UnoJoyProcessingVisualizer sketch.
*Note* You'll need to install the ControlP5 library in order
for the UnoJoyProcessingVisualizer to work. To install that,
in Processing, go to Sketch -> Import Library -> Add Library...
search for ControlP5, install it, then possibly restart Processing.
*Second Note* The compiled stand-alone processing applications seem
to have stopped working, and with Java being a pain, they're not currently
being supported.
You should see a representation of the controller, and if you
ground any of the pins between 2 and 12, you should see
buttons on the controller light up. Now, we move onto the hardware!
Hardware
========
Now that we have the proper code on the Arduino, we need
to reprogram the communications chip on the Arduino.
In order to do this, you need to first put the Arduino
into 'Arduino UNO DFU' mode. The official documentation
for this is here
http://arduino.cc/en/Hacking/DFUProgramming8U2
----HOW TO PUT YOUR ARDUINO INTO DFU MODE----
You do that by shorting two of the pins on the block of 6 pins between
the USB connector. Using a piece of wire or other small metal object,
connect the 2 pins closes to the USB connector together.
(the ones that turn from o to | in the diagram)
---->
o o o | | o o
----| o o o |----| | o o
| | |
USB | |USB |
| | |
----| |----|
|
It should disconnect (be-dun.) and reconnect (buh-din!)
and now show up to your system as 'Arduino UNO DFU'.
In OSX, you will get no feedback from your computer, but
the lights on the Arduino will stop flashing.
ONCE YOU ARE IN DFU MODE
========================
Once the Arduino is in DFU mode, to update the firmware, simply click:
Windows: TurnIntoAJoystick.bat
OSX: TurnIntoAJoystick.command
Linux: ./TurnIntoAJoystic.sh
IMPORTANT: Once you update the firmware, you'll need to
unplug and plug the Arduino back in for it to show up with
the new firmware - it'll just hang out in DFU mode until you do.
When you plug the Arduino in again now, it will show up to your
computer as an 'UnoJoy Joystick'. You can check this by doing
the steps in the next section.
HOW TO CHECK WHICH MODE YOU ARE IN
==================================
On Windows 7, you can check it out by going to
Start->Devices and Printers
and you should see it there under 'Unspecified'
In Arduino mode, it will appear as 'Arduino UNO (COM 23)'
In DFU mode, it will appear as 'Arduino UNO DFU'
In UnoJoy mode, it will appear at the top as 'UnoJoy Joystick'
On OSX, you should see it:
Snow Leopard: Apple->About This Mac->More Info...->USB
Lion: Apple->About This Mac->More Info...->System Report->USB
You may need to refresh (command-R) to see it update.
In Arduino mode, it will appear as 'Arduino UNO'
In DFU mode, it will appear as 'Arduino UNO DFU'
In UnoJoy mode, it will appear at the top as 'UnoJoy Joystick'
On Linux, you can type lsusb to your terminal.
In response you'll get list of all connected usb devices.
From there you should find:
In Arduino mode, you should see a device named Arduino Uno etc.
In DFU mode, you should see a device named Atmel corp. etc.
In UnoJoy mode, you should see a device named Cygnal Integrated Products etc.
**Update**
As of 2021, there has been success using the [jstest-gtk](https://manpages.ubuntu.com/manpages/bionic/man1/jstest-gtk.1.html)
tool to test the joystick once it has been turned into a joystick
There are a couple of programs for creating a quick release zip file.
The OSX one may or may not work; I haven't had a Mac in years so I haven't tested it.
To use the Windows one, you'll need to install 7zip (https://www.7-zip.org/),
then add it to your system or user path (search for Environment Variables, then edit
the Path variable and add the 7zip folder). Then you should just be able to use
Windows Deployment Collator.bat.
With this update you can now make your own steering wheel and pedal set for the racing game
you always wanted to play with controller!
You need an MPU6050 IMU sensor for this project, simply connect SDA and SCL pins to A4 and A5 respectively,
VCC -> 5V GND->GND
or you can use the SDA SCL pins on Arduino close to the GND pin if you need more analog inputs.
You can find the program for the gaming 900 degree wheel set on the UnoJoySteeringWheel folder.
Upload the program and follow the instructions!
Feel free to contact me for any problems on the program : cem.avci@gazi.edu.tr
