Mark,

You discuss about FAT format files on the FlashCard. Eventually I would like
to be able to store a data file onto the FlashCard and then be able to read
it off as a simple file from the card in my PC or Laptop, for data logging
or something.

I'm about to order one of the dev kits but wondered if you we able
(copyright etc) to divulge the simplest method of PC and PIC file writing on
the FlashCard, you mention it and have subsequently captured my interest in
this as well?

Great article by the way. Something I've wanted to do for a long time but
the Flash specifications we just too daunting.

One other question. How did you configure the FlashCard to output it's data
in BYTEs, I see you read the port twice and I'm assuming this first puts the
first word on the high byte of the data bus and data on the low byte which
you cannot read and then the second read puts the 2nd byte of data on the
high byte of the data bus and then the third byte is on the low byte of the
data bus which you cannot read.

Is this how it works? Is there a configuration or pin you've held to force
8byte direct memory mode rather than the IDE mode? I couldn't spot that bit.

It might be easier to direct me to the relevant section in the spec and
where the spec is.

Thanks again.

Pete
