 		 #103643 - no FS
Responding to: ???'s previous message
. Is it possible to access the cards at a "low level"; IE : No filesystem. If so, I assume the cards cannot be read from in your standard card reader. Any suggestions on transferring this data to a windows PC?
Of course you can bit-bang SPI on a PC (e.g. on LPT port) and do everything as with a mcu...A more common approach is to have a single fixed file of sufficient size on the card and only write data in it, in your own "proprietary" format, you only have to figure out where does it have its data sectors.
