FAT12/16 filesystem for ecos

Thanx for your reply. I have written some of the
macros for Big Endian. The GET_BYTES macro uses
function bcopy() to copy 'n' length string for little
endian. For big endian its not as simple as that I was
wondering if a similar sort of macro already exists
that could be used as a starting point
