Hi,

I acquired an 9.7 inch e-ink display which, according to the waveshare, supports partial refresh. I've used their example code for full refreshes, but did not yet find out how to do a partial refresh - the displays refreshes partially, but doesn't display new text in the refreshed area - yet ;)

I'd be very interesting in working on PaperTTY support for this display, but I am new to e-ink displays in general and the 9.7in model seems to work quite differently compared to the smaller models. It uses a IT8951 controller. As far as I understand, I'd need the LUT values for PaperTTY? They seem to be stored in the hat, at least I haven't found them in the demo code yet. And information on the public internet seems sparse.

Anyone else interested in this?
