I have a “P2288” unicorn hat from Adafruit, apparently made in 2016. When I put it on my Raspberry Pi 3B, it doesn’t light up when I power it on. When I run Pimoroni/unicornhat/examples/phat/rainbow.pi, a couple of the pixels flicker briefly, but examples/simple.py does nothing even when I change the set_layout to unicorn.PHAT.
Is there any way to get this running, or is it simply too old and unsupported? Thanks!
