From the HV
list
I'm not sure if this
will
help you, but Craig wrote a document [probably the
most helpful document ever]
about the internal operation of HV. I don't know
what exactly your periodic
event is doing, but you might be able to figure out
what's going on. It's on
their
website at: http://www.csi3.com/app_23.pdf

UPDATE
This
problem with very short lived events and HV doing something else was why I
built the signal extender for my beam
breaks.
As
for
your IR receive question when HV is sending X10 etc. I don't know the
answer.
That one would be best posted on the HomeVision
list.
I
like
the PIC idea and handshaking. It will be interesting to see how well that
works.
Keep
at
it. I have yet to build something that works as I intended it first
time.

UPDATE
Well my hv ir reciever progress was short lived. I cant
get hv to correctly recognise which rx is active. When a (stored) ir
signal is recieved Homevision scans the ir active mux and should detect the
active rx. I tried all sorts but no luck . I also think now the design is
flawed as the ir active signal is only present for approx 1 second ,if hv
is
busy the active signal may be gone when hv does get round to scanning the
rx
mux...
What happens
when hv recieves an ir signal while say transmitting an X10 signal? Does
the
ir signal not get detected?
Im now thinking of using
a
Pic to detect which rx is active and using 3 i/o pins as outputs to
identify
the active rx . Homevision when ready reads the status of its 3
inputs
(connected to ir rx outputs) and determines which rx is active then pulses
a
hv output to ACKnoweldge(connected to a Pic input pin) that it has
decoded the Pics mux outputs . So 4 i/0 pins would be required on
hv....
I was also thinking of adding
an
RS232 port to the Pic so that ir active data could be sent say to a pc. Can
the Girder Software talk to more than one serial
port?
