[Arduino] Library for various Retro-Gamepads (V 1.0)

[GrayFox1985]

Hello

I hope this is not the wrong forum. 

I've made a little library for using various Gamepads with Arduino boards (Atmega untested). At the moment the following gamepads are supported:

| ATARI	| SEGA	| NINTENDO	| MISC
| 7800 1 button Mode	| Master System Control Pad	| NES Gamepad	| Generic 2 Button Gamepad
| 7800 2 button Mode	| Genesis 3 button Controller	| SNES Gamepad	| -
| 7800 2 button Mode	| Genesis 6 button Controller	| SNES Mouse	| -

The library can be found on GitHub. There you can also find a detailed readme and an API-description.

I also created some examples for it.

Example 1: SNES Gamepad as USB mouse

With this sketch you can use yor SNES Gamepad as an USB mouse. It uses the USB-HID functionality of an Arduino Leonardo or Micro to convert the recorded button states into mouse movements and mouse clicks.

| Button	| Description
| START	| Enable mouse
| D-Pad	| Moving the cursor
| B	| Left mouse mutton
| A	| Right mouse button
| SELECT	| Reset sensivitiy
| Y	| Sensitivtiy - 1
| X	| Sensitivtiy + 1
| R	| Acceleration
| L	| Middle mouse button

Example 2: Use the supported Gamepads as an USB Gamepad:

The procedure is easy. My library reads, accordingly to the chosen GamepadLayout, the button states of the connected Gamepads and submits those values to the JoyStickLibrary, which uses the USB-HID-functionalty of the Arduino Leonardo / Micro to emulate an USB-Gamepad.

In the sub-folder 'GamepadUsbControlPanel' you can find the 'Arduino Gamepad ControlPanel.exe', which can be used to switch between the GamepadLayouts without the need to alter and re-upload the code. The GUI looks like this.

The SNES Mouse is not fully implemented in this mode.

Maybe it's useful to some of you.
