Hey,
I'm trying to make a joystick to play flight games with(with arduino leonardo). I did a little research and found the Joystick 2.0 library from MHeironimus.
I then found a code and changed it up a bit to my preferences. Now I have a few questions. I succeeded to let the joysticks work in a steam game but if I turn the joystick one way, I'ts way more sensitive then the other way (this is with both axis). Then my second question is (maybe something stupid) but what is meant by Z axis? If I plug in my PlayStation controller it seems that one joystick is just x and y axis and the other is Z axis and Z rotation, on the code explanation there was also a Z axis and rotation so I programmed my second joystick as it too. I also would like to know what the difference is between a normal axis and rotation.
here is my code
//Arduino Joystick 2.0 Library, by MHeironimus (https://github.com/MHeironimus)
//Initial Definitions and Setup
//Libary Inclusion
#include <Joystick.h>
//Define and Allocate Input Pins to memorable names
#define joyX A0
#define joyY A1
#define joyZ A2
#define joyRz A3
#define joyButton1 9
#define joyButton2 8
//Initializing Axis as Integers, at a 0 default value
int xAxis_ = 0;
int yAxis_ = 0;
int zAxis_ = 0;
int RzAxis_ = 0;
//Setting up Buttons
//Updating a static variable gives greater stability than reading directly from the digital pin.
//Giving Default Values to the Buttons for later use
int lastButton1State = 0;
int lastButton2State = 0;
//Defining the Joystick
//The Joystick is defined in the following setup:
//Joystick(Joystick HID ID, Joystick Type, Button Count, Hat Switch Count, Include X, Include Y, Include Z, Include Rx, Include Ry, Include Rz, Include Rudder, Include Throttle, Include Accelerator, Include Brake, Include Steering
//Joystick HID ID: A Hex value identifier for HID Device Recognition (default: 0x03). DO NOT USE 0x01 or 0x02
//Joystick type: Define the type of joystick from the types supported. Types: DEFAULT Joystick (0x04 or JOYSTICK_TYPE_JOYSTICK), Gamepad (0x05 or JOYSTICK_TYPE_GAMEPAD), Multi-Axis Controller (0x08 or JOYSTICK_TYPE_MULTI_AXIS)
//Button Count: Number of Buttons shown to HID system (default: 32)
//Hat Switch Count: Number of Hat Switches, max 2. (default:2)
//Include X Axis: Determines whether the X axis is avalible for used by the HID system, defined as a bool value (default:true)
//Include Y Axis: Determines whether the Y axis is avalible for used by the HID system, defined as a bool value (default:true)
//Include Z Axis: Determines whether the Z axis is avalible for used by the HID system, defined as a bool value (default:true)
//Include Rx Axis: Determines whether the X Rotational axis is avalible for used by the HID system, defined as a bool value (default:true)
//Include Ry Axis: Determines whether the Y Rotational axis is avalible for used by the HID system, defined as a bool value (default:true)
//Include Rz Axis: Determines whether the Z Rotational axis is avalible for used by the HID system, defined as a bool value (default:true)
//Include Rudder: Determines whether a Rudder axis is avalible for used by the HID system, defined as a bool value (default:true)
//Include Throttle: Determines whether a Throttle axis is avalible for used by the HID system, defined as a bool value (default:true)
//Include Accelerator: Determines whether an Accelerator axis is avalible for used by the HID system, defined as a bool value (default:true)
//Include Brake: Determines whether a Brake axis is avalible for used by the HID system, defined as a bool value (default:true)
//Include Steering: Determines whether a Steering axis is avalible for used by the HID system, defined as a bool value (default:true)
