An online version of this tool is live at http://fsjunior.github.io/image2cpp/
image2cpp is a simple tool to change images into byte arrays (or your array back into an image) for use with (4-bit grayscale) displays suchs as EPDs, like those from Lily Go T5. This is a fork of the javl image2cpp project.
You don't need any special dependencies / internet connection; all the necessary parts sit in a single .html file. So just open this index.html page in a (recent) browser to run the tool. Or you can use the online version at http://fsjunior.github.io/image2cpp/
You can find a simple Arduino example sketch over here in the repository.
I wrote the code with my 960x540 pixel grayscale EPD display in mind, but it should work with most similar displays. You might need to change some export settings; those are explained in the tool.
Initial code by javl with aditional code by (in alphabetical order):
- akumpf
- Daniyal Warraich
- davidalim
- dotcypress
- Harry48225
- hurricaneJoef
- jochenderwae
- plewka
- Sebski123
- whoisnian
- wiredolphin.
The example sketch is based on code by Adafruit. Dithering code from stellar-L3N-etag.
