Hi All
Well
after a
false start with my first attempt at getting multi zone recieving for
HV I
now have something happening. I revamped my prototype and installed a pic
micro
in (pic16F84) to sense the recieved ir signal and then get which rx
is
recieving. To test that it works i programmed my dvd ir codes in hv to do
the
following . The Mute to be detected on zone 1 if so Mute ,the Vol up on
zone 2
and if so vol up and vol down on zone 3 and if so vol down .Next
to
test it on cat5 i connected a zone rx to a point next to my computer, back
at
node 0 jumpered and sent the signals it back to a another socket adj
computer and plugged into zone4. Transmitted on zone 6 (just to test). The
tx
signal is being sent via the cat5. Ive put 3.5mm sockets on the rx box so i
can
get tx signals from my tx unit using a male to male lead. Worked ok
although vol up and down when held pressed every second or third tx gets
thru .
I think maybe to get quick vol up + down send 2 or 3 on each detection i
tried
it seems ok. Next i need to add a chip so that there is led indication
of
active rx (like the tx unit ) build a couple more zone rx units and
test
and then more testing .Will put some pics on my site maybe on the weekend
after
i get the led status working.
Sorry for the long post...
