![]() Unsigned int xAxis_ = 0 // the XAxis needs to be a byte value. The following variable declarations are for our 8 axes that the “Joystick” library can use: Here I am initializing them all to zero so that when the code starts the axes are all set to there zero position. Int button_value = 0 // this is the variable we will use temporarily store the buttons value. Int button_1 = 3 // button 1 is connected to pin 3 Here we initialize it to 0, the not pressed state. Int button_0_state = 0 // the “joystick” library was written so that the value of the button should be 1 when pressed and 0 when released. We will call our button 0 “button_0” which is an int variable (integer variable) Int button_0 = 2 // button 0 is connected to pin 2. The next two lines of code assign button variables to Arduino digital pins (see comments at the top of the page for more info) The ardino IDE needs to have the Joystick library installed or this code will not work. ![]() ![]() Without this line the code will not compile and will return errors. ![]() #include // with this line of code you tell the ardino IDE to reference the Joystick library. The button is the 0-based button number (i.e. The value is 1 if the button is pressed and 0 if the button is released. Sets the state (0 or 1) of the specified button (0 - 15). 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 API is available if the Joystick2 or Joystick3 library in included in a sketch file. The comments below this line are used with the “Joystick2” and “Joystick3” libraries. Only needs to be called if AutoSendState is false (see Joystick.begin for more details). Sends the updated joystick state to the host computer. Set the value to -1 to release the hat switch. 44° is rounded down to 0°, 89° is rounded down to 45°, etc.). Any value less than 45° will be rounded down (i.e. The value is from 0° to 360°, but in 45° increments. hat switch #1 is 0 and hat switch #2 is 1). Sets the value of the specified hat switch. Sets the state (0 or 1) of the specified button (0 - 31). Stops the game controller emulation to a connected computer. If initAutoSendState is set to false, the ndState method must be called to update the game controller state. By default all methods update the game controller state immediately. Starts emulating a game controller connected to a computer. The following API is available if the Joystick library is included in a sketch file. The library (or libraries) should now appear in the Arduino IDE list of libraries. Joystick3 - adds three simple joysticks that contain an X and Y axis and 16 buttons.Ĭopy one or more of the folders (Joystick, Joystick2, and Joystick3) to the Arduino libraries folder (typically %userprofile%\Documents\Arduino\libraries). Joystick2 - adds two simple joysticks that contain an X and Y axis and 16 buttons. Joystick - adds a single joystick that contains an X, Y, and Z axis (including rotation), 32 buttons, 2 hat switches, a throttle, and a rudder. This will not work with Arduino IDE 1.6.5 (or below). I’ve included all the commands for all three libraries for anyone who may want to use those libraries and modify this code.Īrduino IDE 1.6.6 (or above) library that add a joystick to the list of HID devices an Arduino Leonardo or Arduino Micro (or any Arduino clone that is based on the ATmega32u4) can support. ** NOTE: This code only uses the Joystick Library, not the Joystick2, or Joystick 3 libraries so only the commands for the Joystick library can be used with this code. Here is all the code associated with the “Joystick Library”: (These are the commands, API “Application Program Interface” that interface with the Joystick library) The Joystick2, and Joystick3 libraries do not have to be added to the Arduino IDE for this code to work.Īdding the other two libraries (Joystick2 and Joystick3) will not stop this code from working, this code just does not use them. You will want to add the Joystick library to the arduino IDE. ***********NOTE: The Joystick library download included three seperate libraries, being Joystick, Joystick2, and Joystick3. If you do not know how to do this then google it. Download the Joystick library and add it to the Arduino IDE.
