then we read the pulsetrain into nice tidy bits with a proper clock, which
makes the decoder's job way easier. We can actually get rid of the entire MFM
decoder state machine. Also, after sorting out the magic bit patterns at the
beginning of records, we can now reliably pull them out of the bitstream
without needing to know anything about the records themselves.
this makes the hardware considerably simpler and more reliable (as I don't need
to spend time resetting the timers between pulses). Still doesn't help writes,
though. Simplify and improve clock detection; add an abortive attempt at an FM
decoder (turns out that the Brother doesn't use FM).
convert a fluxmap into an encoding_buffer, but locking each pulse to a us grid.
I'm not sure whether this is good enough for reliable decoding, but early
indications look promising.
board... so remove it. Better now. Also realise that PSoC Creator lies to you
about clocks, so adjust the sample clock to be derivable from the USB clock,
making it both the right frequency and much more accurate --- decode success is
dramatically improved (presumably due to less jitter). Redesign the capture
logic to use a timer; simpler now.
