Dear @ZinggJM, Does your library support 5.65inch ACeP seven colors module? If not, Waveshare provides technical specification and Application note reference design documents. Do you need some other things to have initial support for it? Do you have one or plan to have one (Edit: I prepared my post before, and just saw your last message talking about that display)?I'm currently struggling to have some support for this screen module on esp32 hardware, and especially Arduino IDE. Their Arduino code doesn't support it, neither the code for their esp32 driver board... I could only test with a RPi, which is not the target platform I would like to use...Thanks for your help. Best regards.Nicolas

#### Version 1.2.11- added support for Waveshare 5.65" 7-color e-paper display 600x448- the unknown controller of this display doesn't support partial update, as far as known- 7-color graphics support is available with class GxEPD2_7C- 7-color graphics support requires paging even on ESP32- 7-color graphics support causes heavy paging on Arduino UNO, gets very slow- refresh is quite fast for a color e-paper display: 12 seconds
Hi Nicolas,please take a look at README.md of GxEPD2BTW: welcome to the forum! Did you already read General Guidance and How to use the Forum ?Jean-Marc
Do you refer the General Guidance because I sent some links?
Didn't find any answer to my question in this thread: Is it possible to send the processor (ATmega328 in my case) to sleep during paged updates, or while it is waiting for the display to be completely updated? Or is it sending data extremely slowly to the display?
} while (display.nextPage());
So the refresh is at the end. You can comment out the _waitWhileBusy() after the refresh, if you make sure the controller isn't busy when you send the next command.
What would be different if I used the GxEPD2_BW class instead?
I have never tried, as it makes no sense. Might work, but no difference in refresh times.
