Arduino N64 Controller Library
|
||||||
|
|
||||||
|
Based on the work in http://www.instructables.com/id/Use-an-Arduino-with-an-N64-controller/ here comes a comfortable library for usage with e.g. Arduino Uno. For NES there is already http://code.google.com/p/nespad/ . This library uses inline assembly and controllers can be attached to PIN 0 up to 13. But be aware that it's not written in best way possible. Place the folder N64Controller into your folder 'libraries'.
|
||||||
|
|
||||||
|
I used it in combination with TVout ( http://code.google.com/p/arduino-tvout/ ) and EEPROM ( http://arduino.cc/playground/Code/EEPROMWriteAnything ) for highscore I modified an existing Tetris port which itself uses Simple Tetris Clone under MIT license to be useing this library here and the result is quite nice: http://pothos.blogsport.eu/files/2012/03/N64Tetris.zip
|
||||||
|
|
||||||
|
|
||||||
|
Example code for library usage:
|
||||||
|
|
||||||
|
|
||||||
|
#include <N64Controller.h>
|
||||||
|
|
||||||
|
N64Controller player1 (12); // this controler for player one is on PIN 12
|
||||||
|
|
||||||
|
void setup() {
|
||||||
|
player1.begin(); // Initialisation
|
||||||
|
}
|
||||||
|
|
||||||
|
void loop() {
|
||||||
|
delay(30);
|
||||||
|
player1.update(); // read key state
|
||||||
|
if (player1.button_A() && player1.button_D_down()
|
||||||
|
|| player1.button_Start()) { // has no deeper meaning ;)
|
||||||
|
int xachse = player1.axis_x(); // can be negative oder positive
|
||||||
|
// regarding to orientation of the analog stick
|
||||||
|
}
|
||||||
|
// …
|
||||||
|
}
|
||||||
|
|
||||||
|
Wireing:
|
||||||
|
|
||||||
|
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
