Teensy 4,1 & Wii Nunchuck Breakout issues?

Post by jdredd »

Using A Teensy 4.1

Wii Nunchuck breakout adapter @ https://www.adafruit.com/product/4836

I run other i2c devices on it that the scanner can pick up addresses, and also interface with them just fine.

But with the Wii Nunchuck adapter, no i2c address found at all for it.

Went over the soldering for the pins I had to put on and is good.

Does power on ( green LED )

Just no address found.

Tried 3.3V and 5V and nothing changed.

Even tried a 2nd Teensy 4.1 and same thing.

The adapter is just an adapter, it has no I2C address. Do you have a Nunchuk attached?

Sorry, you are correct. The I2C interface is via the Nunchuck itself.

And yes, I have one plugged in. Went through A few here and nothing showed up. :(

Go ahead and try using the library anyway. The Nunchuk can be a bit odd and not respond to the address scan.

On Teensy 4.1 nothing.... lib + example finds nothing.

Found an Uno and tried that and it kinda works. I2C scanning wasn't happy. It would spit out some unknown errors over multiple addresses.

Using the examples... I get output via Serial Monitor for a few seconds, and can see values change a few times when I press buttons and move thumb stick but eventually the UNO quits responding and appears to "hard lock" the Uno.

The main loop quits running.

From out put can see how getting "odd" ascii chars. Sometimes get a few interesting ones to show up at the last dump of data before it stops.

Maybe different generation of Wii chucks are picky or something. I'll have to play around more to see what is up with it.
