A bare-bones, thrown together in a hour, Elf/OS image display utility for Gaston William's PicoElfPixieVideoGLCDV2 Teensy/1861.
It will display images in either 64x32 or 64x64 format, depending on the file size (256 or 512 bytes respectively).
As you might expect from an hour's work, it is delightfully bare bones. But as a proof of concept, it does what it's supposed to do.
There's a few images in the images subdirectory to show what it does.

It's as simple as it could be: a raw image dump. The bytes in the file are displayed as-is by the code.
The source was assembled with a modified version of the
A18 assembler that includes push
and pop pseudo ops. The header files bios.inc and kernel.inc are
slightly modified versions of Mike Riley's files; the #ifdef...#endif
bits have been removed or unconditionally included as appropriate,
#defines changed to equ, and upper/lower casing was made consistent.
