Connecting multiple Wiichucks to a single Arduino is more complex. Search either the comments on my site or on Windmeadow’s site to see what others have done. (also, I think there is some discussion in the Arduino forums on doing this).

I use Arduino 0018.

pls enlighten me guys :D

I was wondering if anyone has come up with a solution to the wireless chuck problem. I would like to use the wireless chuck so that I can build a remote controlled robot for one of my classes.

Also, do you know how the WiiChuck class works from the Arduino Playground? I’ve been trying to play around with that as well but I’m having some trouble. Thanks again for all the assistance and the great library! :)

Instead, do “nunchuck_setpowerpins(); nunchuck_init();” to accomplish the same thing. (This is what the WiichuckDemo sketch is already doing)

There was confusion about the “_with_power()” variant so I removed it. But it looks like I didn’t update this post with those changes. Sorry about that. I’ll fix it now.

nunchuck_funcs.h is in the same directory as the WiiChuckDemo.pde. I can get it to compile if I use nunchuck_init() but not when I use nunchuck_init_with_power(). For now I am just trying to see how to manipulate the different aspects of the nunchuck so that I can later adapt it to different applications. Once I can get the data to print to the Serial communicator I can replace those printlns with something else. For now, though, I can’t even get to that step.

I have a quick question. I try using the nunchuck_init_with_power() function but i get this error:

In function ‘void setup()’:
error: ‘nunchuck_init_with_power’ was not declared in this scope

I am just using the WiichuckDemo from this site so I am confused on what is going wrong. Here is the total program:

/*
 * WiiChuckDemo --
 *
 * 2008 Tod E. Kurt, http://thingm.com/
 *
 */

#include
#include "nunchuck_funcs.h"

int loop_cnt=0;

byte accx,accy,zbut,cbut;
int ledPin = 13;

void setup()
{
    Serial.begin(9600);
    nunchuck_setpowerpins();
    nunchuck_init_with_power(); // send the initilization handshake

    Serial.print("WiiChuckDemo ready\n");
}

void loop()
{
    if( loop_cnt > 100 ) { // every 100 msecs get new data
        loop_cnt = 0;

        nunchuck_get_data();

        accx  = nunchuck_accelx(); // ranges from approx 70 - 182
        accy  = nunchuck_accely(); // ranges from approx 65 - 173
        zbut = nunchuck_zbutton();
        cbut = nunchuck_cbutton(); 

        Serial.print("accx: "); Serial.print((byte)accx,DEC);
        Serial.print("\taccy: "); Serial.print((byte)accy,DEC);
        Serial.print("\tzbut: "); Serial.print((byte)zbut,DEC);
        Serial.print("\tcbut: "); Serial.println((byte)cbut,DEC);
    }
    loop_cnt++;
    delay(1);
}

is it supposed to show tat way?
