4D μDrive-USD-G1 μSD card module


I am trying to log data to a micro SD card using the above devices. I am a bit confused by file systems. My uSD unit supports fat16 file system as well as RAW (first time I have heard of this) i think. It uses SCI for communication with the uC. What do I need to do to be able to write data to the card? Is it a case of downloading a premade fat file system and including the file in my project code? Or is it easier to just write data to RAW?


Ideally I would like the data stored in a .txt file or something similar, but not if it involves complicated programming, so really what's the easiest way of doing it?

I am also open to suggestions of a different SD card module, that might make the task easier.
