No one-way approach to learning ir remote control frequencies

[selbstdual]

Thank you for your answer.

I'm not sure, from your post, what you are trying to accomplish.

I want to know:
a) the carrier frequency of the given remote control
b) which buttons result in which combinations of bursts

I want software in pbp to answer these questions.

Only thing offered is PORTA.5 which can be asked for its status to find out about a high or low level(light or dark).

If you need to know the carrier frequency of the IR you can record an image of it using a PC parallel port and then determine the carrier frequency from the recorded data.

For this issue I wrote this:

All approaches I have seen so far need extra circuitry and output the
data to the pc showing it perfectly. But these are one-way
circuitries. Having found out the frequences, they are useless.

You can also check the files at http://www.RemoteCentral.com for your specific remote or the hardware it was designed for.

It doesn't exist there.

Once you have the carrier frequency and the timings for the IR bursts, you can use HPWM to create the carrier, switching the pin from output to input to turn the bursts on or off.

It is about receiving, not sending.
