Hi,
I'm new to using E-paper display and so I wanted to ask if it was possible to know if
this display was compatible with an esp32 and if it was possible to use it as an image displayer (even one at a time is good).
The official webstore: https://www.waveshare.com/4.2inch-e-paper-module-b.htm
My doubt for using this as an image displayer comes from this line in the official GxEPD2 library repo:
////#include "bitmaps/Bitmaps3c400x300.h" // 4.2" b/w/r // not enough code space
this is on line 137: GxEPD2/examples/GxEPD2_HelloWorld/GxEPD2_HelloWorld.ino
Even though it should only be a 15KB BMP image, no?
Also, I already know it doesn't support partial refresh, and that's not a big deal, I just want to know
Also I'm using this ESP32-CH340 from AZ-Delivery.
I just need to store one image at a time, is it possible?
Thanks,
Best Regards
Good morning,
I'll take a look into it, but by just looking at it, it doesn't look like it's made for the display I'm using, since he's using a tft display and not an E-paper one, also, I looked into the code and it doesn't seem like my concern is answered since he's using 300x200pixel display.
Also, if it's not a problem i wanted to share info with @ZinggJM since he's the dev behind GxEPD2 for as much as i know.
Thanks,
Best regards
Yes, I've seen the image, but still, it's not the same display (this is a 2.7~2.9") display and i know these are compatible with esp32, I wanted support for the model i'm using since i can't find much info. Sorry to bother so much, i don't want to be rude i'm just desperate for info...
PiluDrake remarks: ESP32 is neither __AVR nor STM32F1xx.
regards, Pilu
in case you don't understand: I am referring to
#if !defined(__AVR) && !defined(STM32F1xx)
line 57 of https://github.com/ZinggJM/GxEPD2/blob/master/examples/GxEPD2_Example/GxEPD2_Example.ino
and line 88.
BTW: https://github.com/ZinggJM/GxEPD2 now has enabled https://github.com/ZinggJM/GxEPD2/discussions to ask questions.
Thanks!
