Low power display for Puck (ST7302)

Thanks! That's interesting then - I guess 550ms isn't too painful. It's a lot better than my JS-only solution!

Is there a way of setting the instance from Espruino?

I just looked at the code, and I think what you need is here: https://github.com/espruino/Espruino/blob/master/libs/graphics/jswrap_graphics.c#L579-L583

So all you need is global["\xff"].gfx = g and I think that'll do it?
