Customer:
I’m researching dithering techniques for spectra displays and was very impressed by the images in your crowdfunding post. I saw in theory there’s documentation and extensive examples for that display, but looking at the documentation I haven’t managed to find any. Could you share how you dithered the crowdfunding images?

The dithering kernels are available here: https://github.com/SolderedElectronics/Inkplate-Arduino-library/blob/e58a86619cdc6cbfa3fb6/src/graphics/ImageColor/ImageDitherColorKernels.h#L60
This link opens the GitHub repo branch of the Inkplate library that has the current Inkplate 13SPECTRA library. It’s not released to the main branch just yet.
The reduced diffusion is the best looking one we’ve found. Check out the week 2 progress report for more details: Inkplate 13SPECTRA - Week Two Progress Report | Crowd Supply
