Memory Stick Programming

[David Milne]

Hi All,
Does anyone know how to write data to a memory stick/flash disk/smart
media/etc. card? I have a data logger that I made to run in my PC but as I am
now on solar power, I'd like to make it stand-alone. The idea is to write the
data (generated each minute) into one of these memory cards and then use a
card reader to upload the data into the PC once a week or so. Actually, with
cards upwards of 16MB, I can just about store a year's worth of data - IF I
can find a way of writing to it.
Thanks,
Alan

**I have a Memory Stick PCMCIA adapter. When I use it, the computer 'thinks'
it is just another hard disk drive. I have not tried to write data other
than the regular jpeg files. I also have a floppy adapter and a USB adapter.
If I get the time, I'll see what sort of data I can write to the Memory
Stick.

how do the floppy adapters work?

"> how do the floppy adapters work?


Just fine thanks.

 

[amstereo-matt2]

no i mean, how exactly do they work. how is the head controled, how does it
get handled. i don't understand the workings of these things. i want to
though.

**Buggered if I know. I put a 64MB stick in and the drive 'thinks' it is a
64MB floppy. It is a real hoot. A bit slow though.

**That was a flippant answer. Here's my best guess as to their operation:

The adapter is self-powered (a small lithium battery). Obviously there are
the appropriate connections and electronics to read the Memory Stick. I
would assume that the device has some kind of magnetic 'head' which
transfers the signal to the floppy drive head. Since the sensitivity of the
floppy drive head is high, very little power is required to transfer the
signal.

Thanks for that David, I'll have a look.
