XCore Exchange

Il see if i get to it, what i like about it is that its relay easy to change the storage medium on it as you only have a few commands like sector read and write and such.And it comes with interface code to SD cards, CF cards (That means IDE harddrives too) and USB thumb drives (If the particular PIC has USB host capability)

Altho the thing is written by microchip and im not sure what the licensing allows you to do. I should check up on that. The thing is free on the website but not sure if the license allows ports and distributing.

Okey i had a quick look trough the license agreement for microchips FAT32 code and it looks like i am not allowed to port the code to anything other than a microchip product or distribute the code my self.

I have attached the whole agreement pdf

As i know, for commercial usage, you need a Micro$oft licence, or use some sublicence, as example
from Microchip. It´s similar as for usb VID/PID.
