I saw on your github repo that new panels are welcome for donation. I have this w/b/y BuyDisplay panel that doesn't work with any of the 3 color 1.54" boards in GxEPD2. If you'd still like donations, please PM me with your details and I'll send one of these out to you.
Incidentally, I can confirm that the BuyDisplay 1.54 w/b/r board works just fine with driver class GxEPD2_154_Z90c and the BuyDisplay 2.7 w/b board works just fine with driver class GxEPD2_270. It's just the w/b/y board that doesn't work.
Hi, welcome to the forum, and thank you for your offer.
I am short of time currently, too many appointments.
I intend to take a look at the 3-color displays from Good Display, and check for differences.
Maybe there is a small difference in the code for b/w/r and b/w/y.
In the meantime you could provide a link to the display you bought, and report the inking on the flexible connector of your display.
If I don't see an easy fix, I will come back to your offer and send you my address.

I am sorry, I am not interested in adding it to GxEPD2, as Good Display doesn't have it on offer (any more, maybe). You can try if it works with the driver for GDEW0213Z16 or GDEH0213Z19 somewhat, with modified dimensions, but not likely.
Or check if it works with the Waveshare code for https://www.waveshare.com/1.54inch-e-paper-module-c.htm.
I need to reduce any effort for support of displays that are not used widely.

Oh, you're right. It's the 152x152 display. I hadn't noticed that the buydisplay yellow version was not a 200x200. Makes sense not to support this, as 152x152 in this form factor is definitely not standard these days.
Incidentally, the waveshare code does in fact work with it.
