Comments like this one REALLY pisses me
Off
even though your not refering to my project . If people like you want all
the
bells and whistles you have a price to pay and thats dfevelopement time .
The
person developing this product is paying a higher price in that he has less
time
to spend (and probably out of pocket) with his family as all his spare time
is
taken up trying to provide people like you a cost effective solution to
your
wants and needs......

Sorry
to
drop in half way through the thread and not having read the
previous
posts I hope I don't put my foot in it but here goes.
It would not
take much to build an interface into a PIC to take the
place of HV. The
problem is the IR format I think. There are two
obvious
options
1) Off the top of my head you would need one PIC controller
to set up
the zones and effectively replace HV. This would take a
serial
port.
You would then need another serial port to send or at least
control
the IR itself. Something like a UIRT might work there. A little
bitty
in approach but should work.
Alternatively:
2) You
have probably seen the posts I have put up about the IR units
I am
developing which turn IR into data which can be serially
transmitted. I
don't see why these could not be added to this system
as an interface
to
the PC. There would of course need to be a PC
application and timing
would be an issue but in theory it is
possible. Franks devices (I think
and correct me if I am wrong)
simply route the raw IR signals down to
different zones. I don't
think there is any changing of formats e.g.
>from
would make learning
the IR and doing stuff with the data much
easier.
My kit runs on RS485 as well meaning you can have all the stuff
off
one serial port e.g. the PIC controller for setting up zones and
the
IR interface device.
There are other options depending on Franks
design which can be
explored in the future.
The simplest I think
would be the solution that takes two serial
ports mentioned
above.
Mare after I have thought about it a bit
more..........

p.s. as an example of where it gets more
complicated and the timing
problems mentioned earlier: My Sony telly
will only respond to an IR
signal made up of three identical bursts of
IR over X time frame.
Send only two and nothing happens as I found out
last night:-(( This
is why Siteplayer etc. would not work without some
considerable extra
brains. IR tends to work in real time unlike data
and
some networks.
