SnesLib

Super Nintendo (SNES) input library for Arduino with multitap compatibility

For Arduino Leonard/Pro Micro (5V 16MHz)

Controller compatibility

It's been tested and confirmed to work with:

Accessory	Notes
SNES Digital Pad
8bitdo SN30 2.4G	If on multitap, only works on first port
NTT Data Pad
Super Multitap	Only detected during boot
Naki Tribal Tap	Only detected during boot
NES Digital Pad	Requires simple adapter
VirtualBoy Pad	Requires simple adapter

How to use

Snes controllers works with 5V so I recommend to use a 5V Arduino.

This library requires DigitalIO.

I recommend the usage of SukkoPera's fork of DigitalIO as it supports a few more platforms.

Sample sketches requires uses ArduinoJoystickLibrary.

Install the library on your Arduino library folder. Also install the required dependencies.

Then open any of the provided sketches.

Snes port pins

| 1 2 3 4 | 5 6 7 )

Snes	Description	Arduino
1	VCC/POWER	5V
2	CLOCK	A3
3	LATCH	A2
4	DATA1	A1
5	DATA2	A0
6	SELECT	14
7	GROUND	GND

DATA2 and SELECT are only required for multitap use.

Credits

My friend Rafael for lending me the multitap and the nes adapter.

NOCASH's fullsnes docs.

Darthcloud's Blue Retro docs.

NesDev docs.

It uses the DigitalIO from greiman.

I recommend the usage of SukkoPera's fork of DigitalIO as it supports a few more platforms.

Initial Snes controller reading was based on Snes Library by turicas, but almost rewritten from scratch to support multitap.
