Hi all,
i've read tons of topics but i cannot able to make my wireless nunchuck working.
I have a genuine nintendo nunchuck and it works fine if wired with arduino using library found here.

All ok until here.
Then i'm triyng to make it working using it wireless. i've bought a (cheap) wireless adaptor from nitho like this

Problem is that i read random value of all axis and button of nunchuck. if is not connected i can see no data are read. when i power up i start read random data..
tryed to change initilization code that i've found in one old forum but not solve the problem
byte cnt;
Wire.begin();
// init controller
delay(1);
Wire.beginTransmission(0x52); // device address
Wire.write(0xF0); // 1st initialisation register
Wire.write(0x55); // 1st initialisation value
Wire.endTransmission();
delay(1);
Wire.beginTransmission(0x52);
Wire.write(0xFB); // 2nd initialisation register
Wire.write(0x00); // 2nd initialisation value
Wire.endTransmission();
delay(1);// read the extension type from the register block
Wire.beginTransmission(0x52);
Wire.write(0xFA); // extension type register
Wire.endTransmission();
Wire.beginTransmission(0x52);
Wire.requestFrom(0x52, 6); // request data from controller
for (cnt = 0; cnt < 6; cnt++) {
if (Wire.available()) {
ctrlr_type[cnt] = Wire.read(); // Should be 0x0000 A420 0101 for Classic Controller, 0x0000 A420 0000 for nunchuck
}
}
Wire.endTransmission();
delay(1);// send the crypto key (zeros), in 3 blocks of 6, 6 & 4.
Wire.beginTransmission(0x52);
Wire.write(0xF0); // crypto key command register
Wire.write(0xAA); // sends crypto enable notice
Wire.endTransmission();
delay(1);
Wire.beginTransmission(0x52);
Wire.write(0x40); // crypto key data address
for (cnt = 0; cnt < 6; cnt++) {
Wire.write(0x00); // sends 1st key block (zeros)
}
Wire.endTransmission();
Wire.beginTransmission(0x52);
Wire.write(0x40); // sends memory address
for (cnt = 6; cnt < 12; cnt++) {
Wire.write(0x00); // sends 2nd key block (zeros)
}
Wire.endTransmission();
Wire.beginTransmission(0x52);
Wire.write(0x40); // sends memory address
for (cnt = 12; cnt < 16; cnt++) {
Wire.write(0x00); // sends 3rd key block (zeros)
}
Wire.endTransmission();
delay(1);
can anybody focus me on what could be the problem?
Thanks in advance
