You might want to check out my file system driver. It concurrently supports FAT12, FAT16 and FAT32. FAT16 and FAT32 have been extensively tested. I generally recommend FAT16 for the PIC because it requires less run time overhead.



Dear asmallri,

thank's for your reply. I wouldn't mind paying 75$ for your lib if it works as advertised.. Is there any way that you could provide me with an evaluation version (maybe a hex file with my settings) so that I can test it with my setup ?

best,
Xavier

If you have a HPC (PIC18F8722) with the SD/MMC PICTail then I can send you an image you can test.

Alternatively, you could ask for feedback on this forum for others that have used my software.

Dear asmallri,

I don't have the standard SD/MMC pigtail as I have designed my own circuit board but I used the standard SPI ports (C2->C5) so it should work.. I have an oscillator running at 10'000'000 and yes a PIC18F8722

I want to check if the lib works with my setup, asking people on the forum won't guarantee this..

Please send the HEX file to xavier{d0t]righetti(at]gmail{d0t)com

Thank's man!

.. I had to replace Next_Free_Cluster by Next_Free_Clust. It seems that the lib hasn't been fully tested..

This program(Driver/Library FAT_PIC.C) also at all does not work for me. Except syntactic errors there are many program errors. I have got tired to understand another's errors and to correct them. If I am not right, please prove it. Thanks.

Apparently, I need the full version of winhex to write to the SD.. and I wasn't able to open the disk with DiskEdit.. So I used a freeware called HxD.

I tried to format the SD under windows in FAT 16 and changed the program to FAT16, but under windows, I still can't see the files and folders created by the PIC on the SD. Same operations for FAT32 and same results.. the files and folders are there but I can only see them with a disk editor application.

Thank's!


Indy, did you ever figure this out? I've followed the same path as you, and hit into the same road blocks.
