SDFileSystemVersion2 missing?

Post by dman776 » Thu Jan 31, 2008 3:39 pm

What happened to the wiki User Module section: SDFileSystemVersion2 ??

All I get is a blank page.

There seems to be a problem with the code beautifier for large code blocks. I'll see if I can fix it. In the meantime, I've uploaded the SDFileSystem as a *.zip file which you can download.

I'll have version 3 up on the wiki in the next few days, so watch this space. The main improvement is the ability to use SDHC cards also (although still only those reformatted with FAT16). It also uses improved code for initialising the card, using the SD specific commands.

New features include a function to obtain card type (MMC/SD/SDHC), and one to obtain the serial number from the CID register of the card.

It will definitely be a BETA with limited testing though, so be warned... Keep a copy of the old version!

Regards,

Steve

P.S. Code size is higher, due to more complex Init routine, but maximum read/write speeds using MSSP for SPI are slightly improved if that's a pay-off!!

Steven

Just a quick note - I split the SD library code

=code [=
...
=]

markers as it appears anything over (approx) 100K stuffs the wiki beautifier. When you post an update, just do the same...

Thanks Dave. Perhaps it would make sense for me to leave the new version as a zip download only?

It's entirely your call...It's easy to copy, even when the tags split the code

ok, I must be blind..
(i know... I can't tell the diff between <> and = ) right Steven!

Where is the zip file download of the SDFileSystem module?
I don't see any downloads on the Wiki.

I think that Dave has replaced it with a fixed version of the code in the wiki page itself - simply copy and paste the code into a new file and save as SDFileSystem.bas in your user directory.

Just an update for those interested: it's taken me longer than I first thought to implement FAT32, but I'm nearly there now. A new version of the SD module will be available soon with FAT32 and support for SDHC cards.

Regards,

Steve

Thanks, that would be very much appreciated - I'll hopefully get you a copy of the new module in the next few days.
