And the several pictures show that the card is about 9pins wide
and uses 7 wires.

But he doesn't give the SD's pin-out.
I'm looking for the pinout and the driver algorithm.

Can anybody help please.

== TIA.




Although this NewsGroup still functions well, 
there are already many other previously good

dumbed-down inefficient clik-blogs, we need
to take a stand.

That really gave me a chuckle ;-). Have never known something like that 
exists, very funny.

ROTFLMAO - best I've seen in a while. Well done Don!

The simplified specification is publically available at:

http://www.sdcard.org/developers/tech/sdcard/pls/Simplified_Physical_Layer_Spec.pdf

In terms of interfacing you are almost certainly best of using the
SPI interface since it is the best documented in terms of the freely
available specs.  It is also a direct connection to any microcontroller
with an SPI interface.  I wouldn't bother bodging the connection
- SD card connectors are readily available, e.g. the very first
supplier I checked:

Take a look at the SD card interface PCB and software project here:

Being cheap is easy, but if the project is worth the time,
why not just hunt down a proper SD card slot and be done?
They aren't exactly proporiety, everyone and their brother
making a card reader managed to find a supply.  At worst,
buying a $3 reader you could unsolder the one it has.

Point is, it's easy to let people suggest a simple project
should cost hundreds instead of $10, or be some kind of
concesssion because the project cut corners.  Better to
eliminate  variables, do it as well as possible so if there
is a snag  you have less to question.
