Having trouble getting Wii nunchuck working. Have Mini with robot board. Connected SDA on wii to A4 on robot board and SCL to A5 per directions. Run program and x,y never updates and keep getting this output in a loop. I assume it is something I have not done, but don’t what to look at. tia

Please code highlight your code.
Anyway. No offense, but have you checked if the wii connector is not upside down connected? This can be easily done wrong.

Also, are you using a wireless wii controller or a wired one?

OMG. Thanks Robert. I thought it was a wireless receiver. The directions did not say either way.
After reading your post, I pluged it in and works. dooo.

BTW - I am still getting those GC “dumps” every so often going back to Debug window. Is there a way to turn those off? tia

Glad you got it to work! ;D
The connector on the wii expansion should provide plugging in upside down, but in a rush you can still connect it wrong.

Are you using wired or wireless?

Keep us posted with your progress! ;D
