I had to update Java and reboot the 2.8 inch display. The clock does work on it. But only see the top left corner of it. It cuts it off.
So it does work but just have to fix it a little for 2.8 inch display’s.
Was thinking it be nice if could put a light sensor on the GPIO pins to dim it down as the light in the room goes down. That’s what the squeezebox radio does.
It does seem bright at night time.
I will turn it off on the 2.8 inch display. I guess like you said it can burn it in.
