I thought of building a MMC reader using AVR microcontroller.After searching over the net found the following link-
h**p://instruct1.cit.cornell.edu/courses/ee476/FinalProjects/s2005/acl34/kaos/index.html

These people have developed a complete OS for it.But still i have some doubts.
Can someone clarify about the basic concept that is required for building a MMC reader using a AVR.(i mean wat r the requirements)
What all i need to know before starting this project ?

What i know till now is that they have SPI interface which is also found in AVR.

so can anyv=body please elaborate on how to go about it?

Re: MMC reader

Hi!
This is my idea that you should know:
1. what's the MMC?
2. why do you use the MMC?
3. you have to learn SPI interface (on chip AVRs) to connect with MMC.
4. you have to used FAT (sys files).
.....
final, you have to written code for your project and test it.
.....
Good luck to you!
