Background image upload
This utility encodes an image as a Gameduino character map. A
summary of what is valid:
- width and height must be multiple of 8
- each 8x8 character can use at most 4 colors (although this utility
will palettize each 8x8 cell if necessary)
- no more than 256 unique characters.

Gameduino for Artists for more details
