@IFFrael the chip is pretty easy to connect but difficult to talk to and not well documented. The code is available free on my website (skewworks), just download Pyxis OS, the library you need is called PyxisSD; it should have everything you need.
The original file verges on 3meg. It currently supports 32 & 24bpp (because neither use palettes). I'll be updating it to support indexed images (below 24bpp) with the next os release. The prototype device is done, just working on OS right now.
@13killerx I'm happy to answer questions man but you're going to need to write something I can actually read. "wtf is it wat thes it do?" makes no apparent sense.
This is a 8-bit microcontroller interfacing with a uSD card reader to access files and display bitmaps. Part of an overall project to create an graphic operating system for the chip.
Wow that's really awesome. Tad slow on loading, but it's a feat for arduino. Do you have a website or forum post I can read more about this? Looks really awesome.
Actually it's more of a DOSonCHIP issue. I've maxed the connection out at 60,000bps which yields a 24bpp full screen image @ 41 seconds. Supposedly it can run @ 115,200 bps but ti doesn't respond to read commands at that speed. If I work it out I'll let you know.
I really admire your work, congratulations.

could you share some details of your code and schematics??? I'm having lots of problems connecting this chip. Thanks for your help.

wtf is this?

I thought the description covered it pretty well. Do you have a more specific question?

Nice. Im curious how big (kilobytes) the original file is?
Is 32bpp necessary, or could you use 24 or even 16 for most applications? Have you tested these? Id be curious to see how they went.
