Care to show your source? I am interested in how you stop and start the ESP in order to save juice?

Can you post some sources? Have been fighting with a three color waveshare display for a while now…

@Garry_Glendown The basis with ePaper 2.9 three colors is here, my post # 288.> https://forum.arduino.cc/index.php?topic=487007.msg3533266#msg3533266

Pretty Cool, well done

@Markus_Illenseer I’m working on it … I will publish it completely in time.

@Josef_Zvolanek Great, thank you!

@Markus_Illenseer just Google for esp8266 and deep sleep, it’s built-in. Just tell how many seconds to sleep and it returns to your setup() function. And the e-paper costs no current between updates. :slight_smile:

@Thomas_Runge @Markus_Illenseer Also, remember to connect D0 to reset, otherwise the ESP will sleep forever …
