GDEW1248T3 a 12.48 inch large e-ink display with SPI.http://www.e-paper-display.com/products_detail/productId=414.htmlhttp://www.buy-lcd.com/index.php?route=product/product&product_id=58944http://www.buy-lcd.com/index.php?route=product/product&product_id=58971I had a first look at the specification and the demo code.The controller seems to support partial window addressing and most likely partial update."fast partial update" would require a special waveform table, seems not supported.The price is high for the usual Arduino user, so I see no use to add support to GxEPD or GxEPD2, but who knows if there would be a sponsor or donator.
As for 12.48 inch e paper display,Sorry we can't provide you.Because our customer open this model, it belong them. so I can't provide you controller documents,
For 12.48" e-paper, now couldn't support partial refresh.
Because our customer open this model, it belong them. so I can't provide you controller documents,
But after the "big company" answer from Good Display about sponsoring the small e-papers to support for Arduino users, I currently have no interest to buy from Good Display.
If your enquiry for interest in big e-papers is successful, there might be other donators willing to step in.
See this post for your second question.
The rights to the documents seem to belong to the original customer. They didn't event want to tell me the name or model of the controller used. But the commands look familiar or similar to the partial update capable controllers.
I disagree partly, because you don't understand the e-paper display market.Good Display sells a large amount of e-paper displays to large customers.The hobbyist market is a small segment added, and it is thanks to some sales persons that these e-paper displays became available to us. And thanks to Waveshare who serve also the hobby market with their development tools and boards.
You will understand when you see the announced Arduino solution they will provide.
will you add the GDEW0154Z17 board to the GxEPD2 library.
