I'm building my own custom gameboy mod (not using the old classic housing) and I want to use an analog stick with it. I have found 2 parts of code for the Arduino Micro Pro and they both work (one is from a topic here) but when I combine them the analog stick stops working. I'm not a coder but I know some basics and tried to adjust the code but I only got it so far that I can upload it to the Micro pro.
Can somebody lend me a hand with making this code work? This is the sketch:
Code: Select all
/*
JoystickMouseControl
Controls the mouse from a joystick on an Arduino Leonardo, Micro or Due.
Uses a pushbutton to turn on and off mouse control, and
a second pushbutton to click the left mouse button
Hardware:
* 2-axis joystick connected to pins A0 and A1
* pushbuttons connected to pin D2 and D3
The mouse movement is always relative. This sketch reads
two analog inputs that range from 0 to 1023 (or less on either end)
and translates them into ranges of -6 to 6.
The sketch assumes that the joystick resting values are around the
middle of the range, but that they vary within a threshold.
WARNING: When you use the Mouse.move() command, the Arduino takes
over your mouse! Make sure you have control before you use the command.
This sketch includes a pushbutton to toggle the mouse control state, so
you can turn on and off mouse control.
