Hello to everyone.

I am looking for leads on an IR-learning device or routine.  The application
will memorize and duplicate codes emitted from remote controls.  It will
need to work with a number of different protocols, so it can make no
assumptions about code structure or carrier frequency.

I have spent a lot of time researching IR and I am familiar with the basics,
and I have used a logic analyzer to capture and encode a large number of IR
signals.  What I am looking for is an IR-learner that will learn and encode
carrier frequency, duration of high and low pulses, and the sequence of data
bits.  Optimally, I would love to purchase a component which will do the
work for me and export the results (should be compatible with the 16F877).
Is anyone aware of such a component?

In the event that such a device is not available, I am ready to do it the
hard way.  I have thought through an encoding schema (again, using the
16F877) which hopefully would be a lot more efficient than polling the IR
signal (which would be extremely impractical due to memory constraints).  I
would love to see any resources illustrating how this problem has been
addressed in the past.

I would be grateful for any assistance.

Best wishes,

PS: I have reviewed the archive entries on this issue, but most are over a
year old and they did not contain much information.  I have looked at
Microchip Application Notes, including AN657, and found that those routines
did not meet my requirements.
