hi,
I'm in need of using mmc or sd memmory card in my project but unfortunatly i don't have any idea how they works?
i know they need 3.3 v for working. should this voltage be percise?
I want to read and also write on it in spi mode using an avr. I've used the programm suggested in some relevant sites but it seems there is a bug in those programmes or mey be i can't used them properly.could anyone introduce me a reliable source on this issue?
meny thanks
