I'm trying to read the content of a very small file on an SD card. I've actually already got the card initialization code and block-level I/O done (because I've got mature code from another block-level project). I've got a function that will read an arbitrary block from the volume. All I need now (ha ha) is code to go find, open and read the first block from a statically named file on the volume.
Does anyone have a minimalist FAT library like this?
