Yeah, writing was supported too. Absolutely was the harder part, since you have to worry about allocating new segments for your directories as your filesystem grows. Ironically, looking at my code now, it seems like I never got around to actually writing file contents. I seem to have stopped after finishing the overall FAT16 filesystem structure traversal and mutation. The SD card module was a little simpler, because I only really needed to implement flows for the commands involved in initialization and single-block reads and writes. The SD card presents a block-oriented storage interface, but it doesn’t really care what you’re storing otherwise.
