Yes, you could donate a Lilygo T5 2.13 Epaper to me, or persuade TTGO to send me a free sample.
Then I could try to add support for this e-paper display and its panel to the official versions of my libraries.
@rp6conrad, Hi, welcome to the forum!
Did you already read How to get the best out of this forum ?
For the display section, please always post a link to the display in question, for us to know exactly what you have.
If you use a library version different from the official version available through Library Manager, then you should also provide a link.
I assume you really have this panel: GDEM0213B74.
On that site you find the demo examples from Good Display. You may find a waveform table for partial refresh in one of the examples, most likely in the STM32 examples.
Good Luck!
Jean-Marc
