Sorry
Frank,
You're right,
Keith
already did great things for this group. Supposed to be funny, but
obviously
not.
I'll shut
up....
Sorry if anyone
offended, especially Keith
Nik
Nik
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 IR to data etc. My
system does change the format as above but this 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.

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.
