How get Wii Nunchuck working? Tried several codes but no one is responding or do

hi guys , girls,

i wanna wii nunchuck working @ arudino board. tried several codes tutorials there no working one. got fake chuck , original 1 there no working one.

i tried data , clock @ pin 4 , 5.....and tried power @ original power pins , @ pin 2 , 3 in sketch. didnt tried thing pulldown resistors between power pins , data , clock pins.

can me? have define data , clock pins?



here codes tried:

when "pin 2", "pin 3", "pin 4" , "pin 5" mean "pin a2", "pin a3", "pin a4" , "pin a5", right?

it worked fine me using demo code , wiichuck library:

code: [select]


#include <math.h>

#include "wire.h"
#include "wiichuck.h"

#define maxangle 90
#define minangle -90


wiichuck chuck = wiichuck();
int anglestart, currentangle;
int tillerstart = 0;
double angle;

void setup() {
  pinmode(a2, output);
  digitalwrite(a2, low); // a2 = ground
  pinmode(a3, output);
  digitalwrite(a3, high);  // a3 = vcc
  //nunchuck_init();
  serial.begin(115200);
  chuck.begin();
  chuck.update();
  //chuck.calibratejoy();
}

void showbar(int value)
{
  value = constrain(value ,-255, +255);
  value += 255; // make range 0 512
  (int i=0; i<16; i++)
    serial.print(value >= i*(512/16) && value < (i+1)*(512/16) ?"*":" ");
}


void loop() {
  delay(20);
  chuck.update();

  showbar(chuck.readroll());
  showbar(chuck.readpitch());
  showbar((int)chuck.readaccelx());
  showbar((int)chuck.readaccely());
  showbar((int)chuck.readaccelz());
  serial.println();
}
