No one-way approach to learning ir remote control frequencies

[Ioannis]

Your post, Ioannis, didn't help either.

Ohh, come on, a little humor is always welcome. Don't take everything so seriously!

After all the comments of Dave were sharp enough although the hints that gave you.

By the way, if you use a photodiode (not something like TSOPxxx) you may be able to use the PIC timer and find real time the carrier of any IR control.

An opamp should be used to convert Current to Voltage and feed it to a PIC port like a square wave signal. If you need more on this, ask for it.
