IR Codes Doesn't Control AC

[Lucifer22334]

Hi all,

I am using IRLib2 Library to control TV and AC. My TV is working great after recording raw codes from it's remote and sending it. But my AC is not working for the same. I have a Panasonic AC and tried recording its codes it gave me this:

Code: Select all

#define RAW_DATA_LEN 100
uint16_t rawData[RAW_DATA_LEN]={
	3474, 1870, 298, 646, 298, 1418, 298, 646, 
	294, 646, 322, 598, 318, 646, 298, 638, 
	322, 622, 354, 566, 350, 586, 350, 586, 
	350, 582, 350, 586, 350, 1386, 326, 586, 
	322, 614, 350, 586, 322, 642, 354, 566, 
	350, 586, 350, 586, 350, 1366, 346, 1366, 
	346, 1390, 298, 638, 298, 618, 350, 1366, 
	346, 590, 346, 586, 350, 586, 350, 586, 
	346, 590, 346, 586, 350, 586, 350, 590, 
	346, 590, 318, 642, 386, 554, 322, 582, 
	386, 578, 318, 594, 350, 582, 350, 590, 
	346, 586, 350, 586, 350, 610, 322, 614, 
	294, 622, 350, 1000};

I used this code to send the above raw code but didn't get any response.

I studied that AC IR codes are long codes or say Long signals I used another decoding from AnalysIR. And got codes with hyphens. I wasn't able to find how can I send these codes so moved back to my original one.

I have tried code solution of this but didn't work: https://forum.arduino.cc/index.php?topic=418106.new#new

Got this raw code :

Tried sending through analysir code but didn't work.
Please help me regarding this Problem.

[AnalysIR]

It looks like you ran into a sie limit ith the library, which is common for AC signals.

try this sketch from our blog: https://www.analysir.com/blog/2014/03/1 ... s-arduino/

[AnalysIR]

OK - I loaded the second signal you posted above into AnalysIR, which didnt recognise it at first, but once I used the 'clean' feature it then deocoded OK

Here is the corrected signals:

The minus signs are used to indicate spaces (vs Marks ) of the IR signal. You can simply remove the '-'s when loading into the sendRAW function. However, make sure the first value is always a mark.

I copied your corrected code and tried but still doesn't work. And what did you do for cleaning it?

[AnalysIR]

I copied your corrected code and tried but still doesn't work.

Then it may be that your IR emitter circuit is not great. Post a schematic or photo.

And what did you do for cleaning it?

Our AnalysIR application has lots of features like this & is available from our webshop along with a range of IR modules.

I have tried this. At the end, it has a receiver's code I have used it to decode the Remote signals but didn't work.

Not really sure what you mean here, but the issue may be the same as above. Maybe bring your IR emitter closer to your AC and point the top of the LED at the AC receiver.

Here's the image of the IR transmitter I am using. Ok, I will try doing IR LED close to the AC receiver.



I have tried taking it close to the AC receiver but it didn't work.

Yes

that will not give you much range. It looks like the resistor is 220R. You could change that to 100R or even 68R on a 5V arduino.

Using a transistor to drive the IR LED will increase range a lot. There are several posts on our blog & google about this.

As you said I created the same ckt on a breadboard using 100R and tried but didn't work. I have tried with other AC then Panasonic and some of them are working fine.

Is this matter happens much with Panasonic ACs? And do you provide me with different transmitting and receiving the code then of your AC blogs.

Post the code you are using & a photo of your wiring.

Using a transistor is strongly recommended.

And do you provide me with different transmitting and receiving the code then of your AC blogs.

We sell a wide range of high quality IR software and hardware for makers/diy on our webshop, which will work fine.
