Firstly, thanks for developing the Blinkt! boards – they’re exactly what I was looking for.
I have two of them installed on two Raspberry Pi 3’s. Both are running headless with a minimal version of Raspbian. I’ve successfully installed pimoroni-dashboard on both and installed the Blinkt software via that.
Neither of the boards will respond to any test or demonstration program. One of them has a dim green LED lit near the “!” character end of the board. The other has been permanently dark.
I’m guessing that with this minimal version of Raspbian I’m missing some important driver or kernel module or some component needed to make things work.
Is there a list of prerequisites needed to drive the Blinkt that I can check against what’s installed on my Pi’s? Is there some way to determine if the boards themselves are operational even if a driver is missing?
Any advice much appreciated,
