I am a bit confused about the schematic interface of SD card with ATmega128 in SPI mode. I have read through the posts but am a bit confused.
I am running my micro ATMega128 at 3.3v so, there is no problem with voltage levels between micro and SD card.
I have seen the recommended design on the FatFS link
I could not find all the components.
I have changed it a bit due to the components unavailability.
Do we require to wire the D1 and D2 lines ?
Pls let me know if this works or is there another way of interfacing with Uc.
