Dear HyperHDR,

I have connected a SK66812 LED via Justin's level shifter directly to IRQ18/ground on my raspberry pi 5. I was expecting to run WS281x directly, but then found the RP5 has some major changes.

Device 'ws281x' is disabled due to an error: 'Failed to open. Error message: Hardware revision is not supported'

has come by a few times here on the discussion already.

I then stumbled on this wiki which gave some hope, after building 'insmod' and 'dtoverlay' and running ./test I saw my LEDs twinkle! However, I coudn't get HyperHDR to recognize it. I suppose it's build not to expect this newer module (alterative name? rp1_ws281x_pwm)

After reading more, I decided to buy a 2040 raspberry from itsybitsy. But wanted to leave my expience here for any insights or pointers as I felt I was quite close! Thanks.
