Best of
luck.
Could you not
modify
or even write a quick PIC program to measure the IR signal as seen by a
TSOP
(i.e. a demodulated signal). You could then output this to serial and see
the
differences. They should be quite obvious once you figure out how to
interpret
what you are looking at.
Thoughts?
I cannot help
as
none of my RC5 controls use the toggle bit as far as I can tell. They are
not TV
or vid controls though. I don't know the exact why and how of the toggle
bit but
it is something to do with differentiating between continuous button
presses and
multiple quick button presses. There must be a timeout facility on the
receiving
kit as well otherwise it would not work half of the time. This would
probably be
in the sub 1 second region.

Hi Ian
Thanks
,yes
things are progressing slowly . My friend is doing the pcb so hopefully
he,ll
get it right first go...
I do have CRO but find it hard to sync
it
on the signal . A storage CRO would be nice. Ive tried saving 2 copies of
each
button most appear to work but not reliable enough , the power button gets
detected by hv as the mute button . Ive relearned several times still no
luck
. Im sure someone else must have learned Rc5
codes.......
