we’re poking at our 5.25″ disk drive and we’d like to get it working with our Adafruit_Floppy code so we can read older diskettes. we can’t find our DOS formatted floppies at the moment, we could probably just pop those in and run the USB-floppy interface code to have it show up as a drive. buuuut, we happen to only find our apple ][ and c64 diskettes so far. whoops! well, this is good incentive to get fluxengine support working – it’s an alternative to greaseweazle and seems to support more formats including c64 disks that are gcr instead of mfm encoded. fluxengine has greaseweazle support so it should ‘just work’ right? well turns out we had a few sticking points to getting data read working via the low level win32 com port interface with the CDC class driver (did you know you MUST set dtr? this cool tip could save you 4 hours). now that we’re over that hurdle we can sew up the rest of the interfacing tweaks to get fluxengine working! – video and playlist of vids’ with all the progress!
