[E3-hacking] Config / content filesystem

Sun Apr 21 23:05:19 BST 2019

You wouldn't run imagemagick on the E3 itself. (Apart from anything else
the E3 distribution is, IIRC, something based on OpenEmbedded/Angstrom and
is very hard to get software for?) You'd run it on a PC and use it to
convert files to put on a USB stick, and then use simple scripting on the
E3 to draw them on the screen.

That said, I remember the E3 framebuffer format to be pretty weird, so you
may be better off writing a program (on a PC) to do some kind of custom
conversion. fbset on the E3 should tell you the exact format.
