I have a PIC32 microcontroller with a SD Card attached to my design and I'm using the MDD library to implement an algorithm in order to find a specific file in the SD CARD.
Is there someone, who can guide/tell me, which function should I use?
Use the FindFirst/FindNext functions to search for files. If you need to find a file in a directory tree you can call your own search function recursively:
FindFirst for all files (*.*), if first found file matches the file you're looking for - return result
FindNext in a loop...
If a file matches - return result
If you find a directory, set the current working directory to that directory and call your searchfunction recursively
If you find no more files - return failure
