Just got an e-ink kit working with a Photon. It’s a 400x300 screen so photon has just enough memory to store one image locally. Just started playing with it but pretty awesome stuff. The controller has a single SPI interface with simple instruction set.
You can find the code at my repo, here . I’ll still want to library’fy it with something that can give more automated texting features but it’s a start.

That's awesome! Here's an example of an OLED display that communicates with an SD card, if you wanted to store and display more photos!
With the help of this great community (especially @peekay123 – thanks!) I was able to build my first Photon demo that I would like to share with you. It is a mashup of some code and libraries I have taken from different posts in this forum and external sources. I tried to document this where possible.

What are you going to use the e-ink display for?

Thanks. I updated the info on repo page.
I’ll publish this as a community v2 lib later this week.

wow!! Thank you so much!, I could make it work.
Just one observation, I was using Particle Dev on my Mac, and I had to update:
#include "tcon_mpico.h"
in order to reference the correct file.
Have you tried this extension kit?

One more thing. What did you use to convert the image to a hex array?

It doesn’t work for me. It only opens a window with a message:
“Drag & Drop any file(s) here”, but it doesn’t allow me to do it (Windows and Mac)

It’s not a very friendly tool… it doesn’t say it but it does create the .h file … search your directory (I’m on a mac as well).

I had no luck. I tried through Terminal, and now I see that it’s receiving a file, but nothing else happens
QuestionMark.jpg is a 6KB size image

Oh!, I just found them, they were being created in the ~/ path. You were right, it’s not friendly at all lol

It creates a folder called “PDI441_Converted” in the same dir as your jar file.

This project looks pretty awesome! Is there an easy way to update the image if I don’t want flash firmware each time?
