The menu doesn't reappear when I try and
record a control!
Hold the remote closer and repeat. As a
last ditch effort, touch the remote emitters
to the photodiode. If this doesn't work there
is a problem with your circuit, either the
use of a low quality photodiode or a placing
the phototransistor in the wrong way.
It records okay but when I replay the
device I'm trying to control doesn't respond!
Check to make sure the IR LED was placed
in the proper orientation.
Place the CIR and the appliance as close
as possible and try again. If it works you
may need a brighter IR LED or to build an
additional emitter section.
If only some codes don't work try
re-recording them while holding the remote
either farther or neared the phototransistor.
If you have a hex dump utility, check the
recorded file. It should NOT consist of a
LONG string (>40) of FFs, instead it
should have different numbers in it. The
presence of a long stream of FFs followed by
a long stream of 00s means you recorded the
code too near the CIR. Re-record and hold
your remote control a little further away.
