JP1 Remotes

An idea comes to my mind. My coputer has got a IR receptor. Maybe it'd be compatible with the IRscope. When I was back at home I will try it.

Good news!

Using the suond card to capture the signal it's much more easyer I think it matches with Rob's pattern. Tonight probably I'll check the full signal to confirm this.
Curious, have you considered either purchasing or making an IR Widget so you can use IR Scope instead? It seems like to ...

Good news!

Using the sound card to capture the signal it's much more easier I think it matches with Rob's pattern. Tonight probably I'll check the full signal to confirm this.

Well... after checking my signal by the osciloscope and not get the full wave neither the same times for pulse as Rob, I decided to capture the signal with the sound card and analyze it with a sound edition sofware.

Now I must to go bed cause here it's late. If I'm not wrong, 7 hours more ...

We still playing Knight Rider. Anyway I saw it when I was a child and bought the 4 seasons DVD's. I love that TV serie!

About the specs of my project there isn't so much to say. I must copy the specs of the original controller so everything is based on it.

This is the first time I deal with IR signals. Give me time to develop the project and I'll tell you the way.

So basically, you are looking to have a PIC micrcontroller send the correct IR signals to control the A/C, correct? If so, how do you input the protocol information into the PIC micrcontroller ?

Once you know the binary code you have to say to the PIC when it has to send a 0 or 1. For example ...

I'm doing a climatic control system for a servers room. When the room is 30ºC the air conditioner starts. When it goes donw to 22ºC stops.

This is thought to save money during the winter in a small busines. I know there are systems more efficents but I was ordered to make it with the facilities ...

So, now that we have confirmed that your signal is the same as the one discussed earlier here, can you remind us what you re trying to do? Given that we know the format of the signal, maybe we can help.

Now I see you consider the first peak as a start condition, the second one as a single 1 regardless the time it takes. I was trying to find a pattern to follow based in a piece of time or each bit. It's clear that's impossible cause 0 and 1 have different duration

This info was realy useful for me ...

I don't know if it will be useful for me. Anyway I'll download it at home and I'll try to see how it works.

Thank's

Well, there are some details to get clear because in my screenshot aren't so.

About the frequency don't take so much care. My software doesn't measure the right value when the signal isn't regular. In fact, that fequency changes when I select a piece of the line to know how many time it takes.

The ...

Thank's vickyg2003.

My remote is the same as appears in the PDF manual showed by "The Robman". That's because I thought the codes written by him maybe work whith my project but my osciloscope signal doesn't match with his description or perhaps I don't do the right interpretation. My split is ...

FYI, I found a user manual online.

I've looked at the signals and can see the format. I've also looked at the picture of the remote in the manual and see that it has an LCD screen that let's you see what the settings are. Both of these pieces of information together tell me that all of the ...
