- bert2002 6y agoAlways tried to make the ESP32 fetch an image, but never succeeded (with Arduino though)
- stevekemp 6y agoI setup an ESP8266, (wemos mini-d1), to fetch a remote image and display it: https://steve.fi/hardware/d1-epaper/ https://steve.fi/hardware/d1-epaper/ It wasn't easy as I couldn't get GIF/JPG, or similar, working. As the library I was using used a buffer my RAM usage was twice as much as expected. In the end I used a simple home-made RLE-kinda image encoding. Then I'd stream those updates.
