    Hello,

    I am working with MCF5485EVB. I have a Wii Nunchuk which I need to connect to the board using I2C interface. The connections for Wii are Power(3.3V), Data, Clock, Gnd. Refer to this site if required(http://www.wiili.com/inde...ontrollers/Nunchuk). I have been checking the schematics and board layout but have not found anything concrete. Is there any connector/adapter available which I can directly connect to the board? Or plug the Nunchuk to existing connection on the board.
    I am a Computer Science student hence am not very familiar with this. The final aim of this is to write drivers for the Nunchuk. Please help.

    Thank You,
    Rohit

    On page 2 of the baseboard schematics, you will find J22, which has connections to I2C_SDA, I2C_SCL, and DGND. 3.3V can be accessed from J23 pin 3 (page 3 of the baseboard schematics).

    Hope this helps.
