For years I have been telling the community that flux transition is
easy-peasy on modern MCUs. You have fast timers, "capture mode" and
even DMA for the capture process.
After that, it's mostly a matter of knowing the modulation method and ID
address and data marker encoding.
I routinely use (my own code) the method for getting at the guts of
RX01/RX02 disks as well the oddball ones, such as Wang 2200 hard sector.
My Pertec-interface tape controller is much the same--wiggle the right
lines and stash the data on the internal SD card.
It's not hard!

From what
I've heard, there has been substantial progress on the flux
transition
devices, with decoding the track to sectors, and even support
of some file systems!
