No, the temperature is normal (air-conditioned office environment).
I will try your update algorithm, but I think my problem is related to slow discharge. If I just re-connect the power to my Arduino controller, the e-paper display updates itself and I see original bright display again.
Will replace the display and / or breakout board, may be it is just defective.
I have also a 2" e-paper display from PervasiveDisplays (evaluation/development kit) and it keeps the picture unchanged forever.
Leaking / Losing charge?
I was playing with this e-paper and breakout board and noticed that the picture gradually fade out when disconected from the power supply. In 24 hours the picture is bearly visible. It looks like the display discharges gradually. Is it expected or my sample is just defective?
No public wish lists :(
