AVR-Chat

Well, I guess standard SD cards for cameras and such. Wanted to use the SPI fuction of the card instead of the 4 bit mode. I have one made by Panasonic, 256M, not sure if this has the spi option. There is a guy sending me one that is 128M. I initally wanted a small one like a 16M because the data I am saving is quite small, using 512K eeprom right now.

I haven't looked into it yet (I know 'google'), but is there a specific way to save data to the card so when the card is put into the computer it will open in excell? Do I just add ascII charactures for comma between the data?

Thanks,
Brian
