the first game controller has a joystickIndex of 0, the second has a joystickIndex of 1, and the third has a joystickIndex of 2). The following describes the Joystick library that is included in the updated USBAPI.h and HID.cpp files. Now that the Arduino Leonardo or Arduino Micro has the Joystick library, the Arduino can be used for custom game controller projects. If the three game controller version of the files were used, the third game controller will be tested after the second. Click the second Arduino Micro or Arduino Leonardo and click the Properties button to display the game controller test dialog and observe the test running against the second game controller. The test script will test the game controller functionality in the following order:Īfter testing the first game controller, the test script will perform the same test on the second game controller. While this dialog has focus, ground pin A0 on the Arduino to activate the test script. Select the first Arduino Micro or Arduino Leonardo and click the Properties button to display the game controller test dialog. Select “Game controller settings” to get to the “Game Controllers” dialog.Įither two or three Arduino Micros or Arduino Leonardos should appear in the list of installed game controllers. Next right mouse click on the Arduino Leonardo or Arduino Micro to display the settings menu. ![]() The Arduino Micro or Arduino Leonardo should appear in the list of devices. Go to the Windows Control Panel and select “Hardware and Sound”. If you have a different version of Windows or a different operating system, these steps may differ. NOTE (added ): Due to a change in how the USB functionality is implemented in version 1.6.6 and above, please see Arduino Joystick Library if you are using Arduino IDE version 1.6.6 and above. I have tested this using version 1.6.1 through 1.6.5 of the software. Replace these two files with the following to add a three generic Game Controllers to the Arduino Leonardo and the Arduino Micro:Ĭompile and upload either the UsbDualJoystickTest.ino ( ) or UsbTriJoystickTest.ino ( ) sketch file onto the Arduino Leonardo or the Arduino Micro using the Arduino Software (IDE). Replace these two files with the following to add a two generic Game Controllers to the Arduino Leonardo and the Arduino Micro: ![]() Updating the Arduino Codeįirst make a backup copy of the following two files in the “%PROGRAMFILES%\Arduino\hardware\arduino\avr\cores\arduino” folder: If more complex USB game controllers are desired, refer to the USBAPI.h and HID.cpp files in the Add USB Game Controller to Arduino Leonardo or Micro article. It will not work with the Arduino Uno, because it is based on the ATmega328 microcontroller.įor this project the USB game controllers provided by the Arduino Leonardo or Micro only provide the following: ![]() the Arduino Leonardo and the Arduino Micro). ![]() This project will only work with Arduino products based on the ATmega32u4 microcontroller (i.e. This article discusses how the Arduino Leonardo and the Arduino Micro can also appear as two or three generic Game Controllers. This is a follow-up to the article I posted last month, called Add USB Game Controller to Arduino Leonardo or Micro.Out of the box the Arduino Leonardo and the Arduino Micro appear to the host computer as a generic keyboard and mouse. To add a USB Game Controller to an Arduino Leonardo or Micro using Arduino IDE version 1.6.6 (or above) see the Arduino Joystick Library post. IMPORTANT NOTE: This article is for Arduino IDE version 1.6.5 (or below).
