Re: interfacing sd with pic18F4550 using mikroc compiler
Whats the question? what are you stuck on? There are a lot of tutorials on the web on how to interface a SD and mmc card.
Unfortunately most of the tutorials have errors or omissions and the manufactures data is very hard to understand. I can answer all of your questions but I will not write your software for you (unless you pay me).
There is often libraries available to do what you want, but you will never learn anything by using them.
