Right now the GDE060BA with the DESTM32-T is the best and only choice. And it costs less than a Kindle.
I expect there will soon be a demo example for the 8" parallel IF for DESTM32-T.
Waveshare has a 9.7" on offer, but no demo yet.

I can't find it on the good display website, only on alibaba, and no refresh data on alibaba.

Is it supported by your library?

Would like to, but don't expect to get a sponsor.
The questions were about your suggested 7" screen
GDE06BA

A preliminary version for Good Display HD e-papers on DESTM32-T is available: GxEPD_HD

For use with GDE060BA panel.

Tests and enhancements are ongoing.

6 inch b/w e-paper display with parallel interface, with 16 grey levels. GDE060BA, name fixed, sorry.

It seems nice, even though a little bit small.
 
What is the refresh time for a small portion? (character typing refresh time for example)

EDIT: 260 ms for the entire screen

Ok I'm getting more deeply into it.
I'm looking at the code and I'm trying to find a guide for the hardware connection to my D32 pro of the DESTM32-T panel.

I know it could be boring but in the demo example maybe could be useful to comment quite every command, for example:
Code: [Select]

display.setRotation(1); //1 is the value for the rotation etc.....

display.fillScreen(GxEPD_WHITE); // here I'm doing this thing etc...


Because it's not immediate to come back to the library for a "simple user" maybe two words can make this library even more useful.

Beside this, it is a very nice work, congratulations.

The DESTM32-T is not a panel, it connects to the e-paper panel.

It is a complete system, that can run the demo example, or the GxEPD_HD_TestExample, or an application using the GxEPD_HD library.

You would need to develop an example, a bridge application, to connect to your external processor.

But you lost me anyway, as I said, I take a break from this work. GxEPD_HD will remain in this initial preliminary state.

So let's make some order.

1) The library (as it is) is working for the GDE060BA?

2) I understod that your problem was to work on screens you don't have, so I thought you were talking about new screens implementation

3) Your demo code must be loaded on the DESTM32-T by the arduino IDE?

4) The DESTM32-T has some serial ports to be connected to a standard arduino board?
