/**
* Gamecube controller to Nintendo 64 adapter
* by Andrew Brown
* Rewritten for N64 to HID by Peter Den Hartog
* Modified to be a library by Kai Lüke
*/
/**
* To use, hook up the following to the Arduino:
* Digital I/O 2: N64 serial line
* All appropriate grounding and power lines, i.e.
* GND to left N64 controller PIN, Dig.PIN2 to middle Serial/Signal,
* 3.3V to right N64 PIN
* /------------\
* / O O O \
* | GND Signl 3.3V |
* |________________|
* Maybe: connect PIN X with external 1K pull-up resistor to the 3.3V rail
* Default and fallback PIN is 2
