Wireless SNES controller via I2C Nunchuk interface

Rayman

Just tried this out and looks like it will work

There's this <$4 wireless SNES controller on Amazon: https://www.amazon.com/gp/product/B07BT3QRT3?th=1

Looked like Nunchuk connector to me, so I tried it out and appears to work...
Adapted Jon's code just a bit from here to show binary data: https://forums.parallax.com/discussion/130118/wireless-nunchuck-it-works

The data is a bit strange, but each button does affect at least one bit. But, some affect 4-bits and some 8-bits, so it's a bit weird.
Fun puzzle to solve. Definitely looks solvable though...

Planning on including 2 of these connectors on my first P2 board so can play multiplayer games with wireless controllers

Classic Controllers have a different report format from Nunchucks.

Your controller, being made for SNES mini, doesn't have all the inputs, but the format is the same.

Thats so cheap for a game controller, wow.

Fingers crossed you can get it working Rayman

The board looks nice too, is that a P1 driving things?

Rayman

In the photo, yes. That’s a P1 board with ssd1921 graphics and 3.5” touchscreen. It’s been a useful board.

I went to buy more, but there’s a hard limit of 2 per person for the cheap version...

Nice! However, if I were you, I would try to complete the schematic as far as possible before delving into the layout. I would also place the decoupling caps first.

I'm intrigued by some traces already going to the bottom, without any reason to. It seems that you have the layout already figured out and you are making room for future components.

Kind regards, Samuel Lourenço

I’m just getting started on the layout...
Hope to have done just in time for P2 chips
