detecting remote control code pattern of any arbitrary remote.

[Disha Karnataki]

i have a remote control & want to use it for my project but, i do not know it's protocol so that i may exactly decode the codes for particular keys. how do i detect protocol know?
i do not think it has rc5 protocol i got it long back i really do not remember then, know how do i start it.
or i mean to say how do i know whether it uses any known(rc5..etc) protocol or not?

I assume that you are talking about a domestic Infrared remote control? Your post is not clear.

A logic analyser is the best tool to analyse bit patterns, preferably at the output of a 3-pin IR receiver module.

A good oscilloscope connected to the transmitter LED would be the best tool to determine the carrier frequency.

Once you can see the bit pattern and timing, compare against the IR information given here:

Alternatively - buy a remote control that comes with some information. - or use a Sony TV remote control, which has a well documented protocol.

i knew that i had to use logic analyser or oscilloscope.
But now i donot have any of them right now with me so, how do i find which protocol that remote control is using?
i went & asked the shopkeeper whether he knows for which tv it's used but, he is also clueless.
then, i asked whether i will get any philips tv rc but,he said there are many model in them & which i would like to have & he also said that the circuit within it changes for different models of the philips brand. I do not think he meant the protocol changes what do u say?

Looks like you already found the protocol using sound-card oscilloscope - as you explain on your other thread.

And it IS RC5 protocol after all.

Best to close this thread and continue on the new one. Running two threads on the same subject is confusing
