I dimly remember an article in Circuit Cellar that showed a CF card being accessed via SPI, and using a FAT12 or FAT16 file system.
Has anyone had any recent experience with making this sort of thing work? Any good libraries out there to use?
I'm doing this right now using (my modified version of) Lewin's DOSFS
and bit-banged SPI handlers on the i8096 for an MMC card; I will post
a link to the code when it's done. Are you sure it was a CF card
that you saw in the article, over SPI? If so, do you remember if
Ciarcia built a custom controller for it?
I was also looking at Lewin's file system, so I'll be interested to hear how it is working for you.
-- and it wasn't Ciarcia; his name isn't on the by-line of many articles in the magazine these days.

Do you need to implement control loops in software?
"Applied Control Theory for Embedded Systems" gives you just what it says.
