    I don't understand why you would think I do - I explicitly stated that interrupts are better and more elegant. But from your comments it seems like you are new to this, so I tried to address some aspects that are...

    You can daisy chain 8 MCP23017s off one i2c bus, giving 128 (interrupt capable) digital pins. That would support 64 encoders (if you're not using switches). And the Teensy 4 has 3 I2C busses, so you can support...

    I have just returned to this and your code looks very promising, so I had a go with the Audio Library object version. I am using a Teensy 4.1 and the problems I describe occur with both the audio shield and I2S into...
