Need help finding the root cause of Waveshare 2.13V3 noise
I ported epd-waveshare V2 to async Rust, ran the sample on battery power using a 3.3V LDO. I did it in Partial Refresh mode. During this, display border appeared along with all that noise.

A WiFi color eInk picture frame
If anyone wants to make a similar project, there is a great Rust API to most of the Waveshare displays[0] (I added support for the display mentioned in the article 5in65f).
I also made a project[1] with it that generates art using a gameboy emulator and some static images and other transforms to show on the display.

A WiFi color eInk picture frame
This is the same e-ink device I believe that's in the Pimoroni Inky Impression.
I've written a Python program that anecdotally fixes the bias caused by the display for blues and greens, and dithers using an Atkinson dither. The code is based on some older Java implementation I wrote, but this is more succinct (and has a colour fix) if you are considering a port to C (entry point diffuse_image()):
https://github.com/KodeMunkie/inky-impression-slideshow/blob...
The fix is to define the ink's blue as a slightly different hue than the device specifications, which tends to over emphasise it - improving it - when it comes to shades like royal blue (which the display can't achieve).
