[General] Can I use 1Gb SDcard with SDIO interface ?

Guys,

Can I use 1Gb SDcard with SDIO interface ?
Usually I use SPI for accessing this SDcard,

Any clues ?
Thanks

Yes. Hopefully the next question isn't "How do I handle the SDIO interface in software"?
I presume there are code examples.

Hello,


I am working now on a similar subject.. use an 2GB SDcard to store data on it.
I fund many documents on the web about this subject..
and the main key is to have an MCU with enough Ram inside.
I work with a PIC18F26K22 (or 46K22) with has 3K ram, so it is possible to use 512 bytes of RAM as a buffer to store one sector.
SDcard must be formatted with FAT32 and sector size of 512 bytes..
I allready put my first tests on my web page .. here
source is C18 Mplab
