FAT file system

FAT file system

2004-09-20 by Gus

After a long time of work I am finally done with ALFAT. I used ARM 
chip and programmed it with full FAT file system where you can send 
SPI or UART(serial) commands to it and it will save FAT files to 
many kinds of medias SD, MMC, CF and hard disks!

I would be more than happy to hear what you think.

Thanks for your time,

implementing simple read file on FAT is not hard but when it comes 
to having FAT12, FAT16 and FAT32 where you do read and write is not 
a simple task. I started my project with 8-bit micro and it was very 
slow and the chip got filled fast. anyway....the idea here is that 
you don't have to worry about file system stuff as ALFAT will do the 
job.

hmmmmmmm, pack of beer! as far as I know, FAT source code costs 
$4,000 and up so if you know otherwize please send me a link to that 
website

RE: [AVR-Chat] FAT file system

2004-09-20 by Lasse Madsen

What are your plans for this?

Seems to me like a bad investment to put an extra IC and what ever comes along with it on a board to implement a FAT file system when an ATm128 can do it with out problems.

And one can purchase the royalty free code almost anywhere on the internet for a pack of beer :-)

Hi Gus and others...
 
Have a look at this from PRLLC
http://www.prllc.com/prllc_homemainFlash.htm it's a 139 USD (ok maybe a
little more than a pack of beer but certainly dirt cheap)
I've used it with both ARM and AVR with much success with will both read
and write FAT12 and FAT16
 
There really isn't any need for FAT 32 in an embedded application using
either AVR or LPC ARM I have never seen a place where it was necessary
to log over a GB of data.
FAT32 reading would be nice tough but then again even my brand new
Panasonic video camera doesn't support FAT-32 so why bother :-)
 
Gus I think you have a nice application but make your product a source
code solution and at a price like PRLLC (maybe a few hundred more if
it's really that great) because a lot of people my self included wont
purchase an IC solution where all you could settle with was in fact the
source code. I've been an embedded designer and programmer for more than
four years now and educated electronics mechanic of background the only
things I purchase (IC) is processor, RF integrated IC's and such things
that cant be made by one self.
 
I would think around 350$ was adequate for code like that but maybe you
cant sell it to that price and that's ok.
 
That's just my thought
 
Best regards and I hope you will make fortunes on your product :o) 
 
Lasse Madsen

Looks good and GPL, well written and commented,

Move to quarantaine

This moves the raw source file on disk only. The archive index is not changed automatically, so you still need to run a manual refresh afterward.
