alt Hacker NewsAnyone know what the refresh rate for these displays are, at least with the stock firmware? Reading the datasheets didn't help, though maybe I didn't know what to look for.

Data sheet seems to say (Page 8 -https://cdn-shop.adafruit.com/product-files/6397/P6397+C2226...):
> Image update time - 25 ºC - - 4 - sec
I'm guessing you could probably push that somewhat by going beyond the specifications, would wager a guess how far though.

Partial refresh on these can often be surprisingly fast, even when full refresh takes seconds

The datasheet says 4 seconds for the image update time. However, I didn't found the time for partial refresh.

Probable seconds per frame at least.

Assume slow
The refresh rate of eink is kind of...muddy. It depends on temperature and target contrast. With the right waveform and voltage, you can push it pretty far(like 30hz+).
The thing is, Eink's waveform is kind of secret afaik, everyone has different tuning.
