No one-way approach to learning ir remote control frequencies

[dhouston]

It doesn't exist there.

There is a file there for a Scott DVD player. If they make other models there is still a good chance that they use the same carrier and codes.

Since you apparently want someone to hand it to you on a plate, try http://www.rentron.com/PicBasic/IR_Chips.htm

I still really do not understand exactly what you want to do but, from a quick look at some of your other posts, that seems to be an ongoing theme.

The Scott DVD Player uses the NEC IR protocol with a carrier of 38kHz. Scott's custom code is 8. The NEC protocol is one of the oldest (if not the oldest) IR protocol. It is widely used by many AV manufacturers and is easily understood. There's a datasheet for one of the early NEC encoder chips on my webpage at http://davehouston.net/Nec6121.pdf.

If you want to capture these codes with a PIC, the best way is to use an IR receiver module which receives the IR, removes the carrier, and outputs the data envelope. I suggest the Vishay TSOP1100 which works with 33-57kHz carriers. If you also want to capture the carrier frequency use a photodiode on another pin and, if your oscillator is at least 8MHz, use PBP's COUNT for 1mS during the initial IR burst which is usually 2.5mS or longer with almost all protocols. The initial burst is about 9mS with the NEC protocol.

As it happens, I've posted code to send/receive, encode/decode the NEC protocol as RF. The only difference for receiving is the polarity - the IR receiver is active low where an RF receiver is active high. For sending, modify my RF code with Bruce Reynold's IR code which I cited earlier. You can even leave it at 40kHz but you'll need to use the NEC timing in my code.

I want to know:

Apparently everything...right...DUDE?

I want software in pbp to answer these questions.

Of course you do! As usual...

I don't think the plate is good enough. Hand delivered, built, tested, debugged, and put in a shiny gold enclosure...maybe...

I did not notice this sentence.

Interesting that no technical manual can be written for a good
understanding. Thank you anyway.

Let us see.

While this is written about how ProntoEdit displays IR codes, it gives a good explanation of both one Sony and the NEC protocols.
http://www.remotecentral.com/features/irdisp1.htm

This gives brief descriptions of 4 popular protocols. http://www.celadon.com/infrared_prot...ls_samples.pdf

This is probably the best one as it includes PIC (ASM) code. http://www.sbprojects.com/knowledge/ir/ir.htm

I don't understand you. Does your text support my question in a way ?

[Acetronics2]

Hi, Selbst

Could you confirm your very approximate English translation of " Ich wünche " or " Ich Möchte " is " I want " ...

... " I'd like " is much, much, much closer and could bring you back much,much,much useful answers ...


But ...may be I'm wrong ...

No. It is a notice to skimask.

I decided to say it the way I did And Acetronics, I am waiting for the nazi-comparison impatiently. Do it, let it out.

No. It is a notice to skimask.

He/she has already been on my ignore list. I don't know why but I guess he/she proved in the past that his/her comments need noone to watch them.

Your post, Ioannis, didn't help either.

Speaking of comments:

Thanks to dhouston for his effort.

I don't get it either...
