Wii Nunchuk and VE at the same time

Hmm, that’s not as consistent as I’d hoped. It’s better, but I still lose the ability to read the Nunchuck depending on the video signal entering the VE.

I’m sooooo close to getting this working, but I’m running out of things to try.

I’d consider using an analog joystick instead of a nunchuk. I don’t know what your project is, but maybe that will work. Doing video on an Arduino is nothing short of a hack, so it’ amazing that we can get any I2C to work, given the sensitive timing of digital protocols. I have no idea why your timing is different depending on the bits in the frame buffer.

Yes, I’d come to that conclusion (use analog joysticks) too 🙂

I know the VE uses digital pins 2, 6, 7, 8, and 9 – does it use any analog pins as well?

Many thanks,

Yes, it uses A2. As documented: nootropicdesign.com/ve

Thankyou 🙂

Hi Michael,

Here’s the controller I’m working on, minus the lid. The whole lot seems to work very well – thanks for your help!

The AV receiver for the wireless camera on the ROV is in the background.

Wow, very nice!

And here’s a repackaged version:

I applied the additional 330ohm resistor as suggested here:

This has made my overlay much brighter.

Thanks for an awesome product!
