Hi Marcel,
first of all, Merry Christmas and thanks for your quick response!
OK I hooked the ESPaper up to a Console and logged it, you can find it below.
I believe, I have an issue with the epaper screen, as it does not change at all. The controller says it sended something to the screen, but I see still the "Initial Setup" screen. Do you know the assembly process, when they manufacture the devices? Is the screen programmed with the "Initial Setup" actually written with the very controller it is put together in the enclosure, or are the screens "programmed" from a different controller and then put together?
Do you have any further suggestions? Is there a test sequence program I could start/flash to the device to see if the screen is working (refreshing) properly?
Best Regards!
Sergio
