Are you aware that the UART decoder extracts the bytes for you
when you move the sample point away from the center of the bit
time towards the start of it? See the attachment (assuming that
I don't forget to attach it).
Which suggests that SCS could and probably should stack on top
of UART, very much like MIDI, DMX, LIN and others do.
And I do agree that before any decoder implementation it's
essential to have documentation/references/details on the
protocol, and captures for demonstration. I consider this even
more important than any implementation itself, since the
information is need to create a proper decoder in the first
place, and maintain it later on.
Is the SCS protocol comparable to other home automation setups
like KNX or EIB? Searching the 'Net suggests that "simplified
wiring" is rather generic a term, brings up boats, motor bikes,
and houses.
