I'll send this again.. fell for the no pic tag again. doh!


As some of you may know, I'm working on a full FAT32 and IDE implementation
for either PIC, SX.. or any of the other popular microcontrollers (writing
in C). Supprisingly, thats the easy bit. So fat I am doing directory
listings, change directory and read files all with about 512bytes of buffer
for the disk sector and an additional 40 or so for keeping track of fat and
partition associated things. I'll be starting on writing to files sometime
after the Christmas and New Year festivities.

Here's the question: How do you- the (potential) users of this project want
to interface to the filesystem- both in terms of hardware- i2c, spi,
something else.. and software - functions you would like implemented for
manipluating the files on the drive.

So far, there's the directory functions- readfirst, readnext, change
directory
and a couple of file functions spoolfile which just reads the whole thing
and streams it to your device.. and filesize .. obvious ones I havent
implemented yet are are seek to position and read a single byte..

Any suggestions much appreciated.
