SD CARD Interfacing to AVR Atmega16 Microcontroller [Help Needed] [Simulation]

[umairmukati]

Hello,
I am trying to interface SD card using it's datasheet at with customized code, stucked in an unknown error.
Kindly, if any one can resolve this issue then it will be nice.
I am attaching whole of my code with the customized libraries, as well as proteus simulation.
Thanks in Advance.! :|

Your mcu is set to 1MHz core speed, was that your intention?

What kind of error do you get, you have to describe what is going wrong.

The problem is resolved now, I am now able to write and read the MMC card.
Do you know any hack for which I can test an SD card on Proteus ISIS, instead of a MMC card?
And do you wan't to give me any suggestion regarding fat16 file system implementation on SD card?

I haven't used any SD or MMC

how did you resolve the issue.Can you post your new code......................
Also, the mmc in proteus should work well for sd too.....

You can use a dummy file like filename.mmc with proteus to test the SD/MMC card simulation.
