Original GitHub issue: https://github.com/OpenEPaperLink/OpenEPaperLink/issues/338

The wiki states that the following is supported :

BLE based (Gicisky/Picksmart)
2.13" TFT
2.13" EPD
2.9" EPD
4.2" EPD

There are other sizes, like 7.5 and 10.2, available from Gicisky. Are these also supported?

@ptahbe
I could also add them if I got my hands on one of each, but currently there is no plan to spend that money from my end

@atc1441 I have one of the 7.5 BLE units here. Is there anything I could do, scan/capture to help? Can confirm the 7.5 does show up just in the oepl web page but loads as a 296x128 fw:257 0x101 , Also doesn't update the units screen.

Using 800x480. compress,mirror and 2 colour. It does update the screen. but it comes out upside down and inverted with both the red and black txt coming out as white. Do the same as single colour get the same just with a red/black noise background.

Not sure what to try next

@atc1441 I too would love to see support for the 7.5" Gicisky ESL.

I'm happy to help in any way to contribute this - where do I start?
