Hi all,
I’m trying to hook a Wii Nunchuck up to a Teensy 4.1 over I2C. Using the built-in I2C scanner sketch from the Teensy Arduino examples, I can successfully detect an MPU-6050 and an OLED display. So I am pretty sure about that basic I2c works with my setup.
But when I plug in the Nunchuck, though, every address returns an error:
Unknown error at address 0x01
…
Unknown error at address 0x7E
It fails on every address. I’ve double-checked my wiring (using 3.3 V) and even tried three different Nunchucks with the same result. Has anyone gotten this combo to work? What obvious step might I be missing, or have I just gotten three dead controllers?
