SD card source code

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:

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:

Tressie.

Oops! I think I meant here:

Tressie.

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.

ROFL!
