MicroSD Cards and SDFS

[rsocor01]

Hi all,

Well, this is probably a very dumb question . I'm trying to get a MicroSD card to work with SDFS. The first question I have is about the pin names. In the schematics provided in the SDFS zip file there are 12 pins for the SD card, and they are named as

• CS
• DATA IN
• Vss
• Vdd
• SCLK
• DATA OUT
• CD
• WP
• GROUND

Plus some NC pins. Now, all of the SD cards that I can find have 8 pins named as follows

• DAT2
• DAT3/CD
• CMD
• VDD
• CLK
• VSS
• DAT0
• DAT1

So the question would be, how do you relate one to the other? Am I talking about two different things here?

My second question would be about about the PIC speed when initializing the SD card. Do I need to slow down the PIC to initialize the SD card?

Thank you all for your help,

Robert
