Hi,

Can someone please point me in the direction of some documentation
that describes RC5 code creation.

I have had a look through the forums but can't find anything
that really explains how they work or how to create them.

Here is why I need help.

I have some Gefen codes.
I learnt them with the RTI learner.
Analyzed them with IRtool.
regenerated them with makehex.
So far so good.

Here is where I have issues.

The generated codes work 100% on a Nevo but will not work
on an RTI. The learnt codes work on the RTI. My understanding
is that the RTI learner does not like RC5 codes all that
much.

Rather than asking for someone else to fix the problem
I wanted to try myself first.

I have read the documents on pronto codes available on
this website but they don't give enough info on RC5.

Any help on the code format would be greatly appreciated.
