Nyko Nunchuk Wireless I2C

I have tested the generic china wireless nunchuk and the corded Wii nunchuck
and both seem to work correctly with the I2C interface...

The Nyko wireless must have some differences, timing I suspect or initialization ( not suspect , as this should stay typical to work with the Wii platform)

anyone have any experience with the Nyko ?

I'm not using the Arduino board, rather I'm using a Rabbit Microcontroller board, generating I2C signals.

does anyone know of the correct I2C routines for the nunchuks.

I've tested the Nyko with the Wii system and it is functional so I don't suspect a bad controller.

thanks
Chuck
