Problems to send IR signals to Panasonic AC

Post by marcbeeh »

Hi,

first of all thank you for the helpful instructions on your webpage. I'm currently trying to set up a remote control for a Panasonic AC based on an Arduino 2560 board. After some issues in the beginning, I was able to capture signals from my AC's RC with your LongIR script. Here is an example of the signals I captured:

AC on, 21 °C, Fan Auto

Code: Select all

(439) 3504, 1684, 472, 412, 444, 1268, 444, 392, 468, 388, 472, 388, 468, 392, 468, 388, 472, 392, 472, 392, 468, 388, 468, 392, 472, 388, 468, 388, 472, 1240, 472, 388, 468, 396, 468, 416, 444, 392, 468, 388, 472, 388, 472, 388, 468, 1268, 444, 1244, 468, 1272, 444, 388, 472, 388, 472, 1240, 468, 392, 468, 388, 472, 388, 472, 388, 472, 392, 468, 392, 472, 388, 468, 416, 444, 412, 448, 388, 472, 388, 468, 388, 472, 396, 468, 388, 472, 388, 472, 388, 468, 392, 468, 388, 472, 388, 472, 388, 472, 392, 472, 388, 468, 392, 468, 392, 468, 388, 472, 388, 472, 388, 468, 392, 468, 420, 444, 388, 472, 1264, 444, 1268, 444, 392, 468, 392, 468, 388, 472, 388, 468, 392, 472, 9840, 3508, 1708, 444, 388, 472, 1240, 472, 388, 468, 392, 468, 388, 472, 392, 464, 392, 468, 396, 468, 392, 468, 392, 468, 392, 468, 388, 468, 392, 468, 1268, 444, 388, 472, 396, 468, 388, 472, 388, 472, 388, 468, 392, 468, 392, 468, 1264, 448, 1240, 468, 1248, 472, 388, 468, 416, 444, 1244, 468, 388, 468, 392, 468, 392, 468, 392, 468, 392, 472, 388, 472, 388, 468, 392, 468, 388, 472, 388, 472, 388, 472, 388, 468, 396, 468, 1244, 468, 392, 468, 388, 472, 388, 472, 1240, 472, 1264, 444, 392, 468, 396, 468, 388, 472, 1240, 472, 388, 468, 1268, 444, 392, 468, 1268, 444, 388, 472, 392, 468, 392, 468, 392, 468, 388, 472, 388, 472, 388, 468, 392, 468, 392, 468, 1260, 472, 1268, 444, 1268, 444, 1264, 444, 1244, 472, 388, 468, 1268, 444, 416, 444, 1244, 472, 388, 472, 388, 468, 392, 468, 388, 472, 388, 472, 388, 472, 388, 468, 396, 468, 392, 468, 388, 472, 388, 472, 388, 472, 388, 468, 388, 472, 388, 472, 392, 472, 388, 468, 1268, 444, 1240, 472, 392, 468, 388, 472, 388, 472, 412, 444, 396, 468, 388, 472, 392, 468, 388, 472, 388, 468, 392, 468, 1268, 448, 1264, 444, 392, 472, 388, 472, 388, 468, 388, 472, 392, 468, 388, 472, 388, 472, 388, 468, 420, 444, 392, 468, 388, 472, 388, 472, 388, 468, 416, 444, 416, 444, 388, 472, 396, 468, 388, 472, 388, 468, 416, 444, 388, 472, 392, 468, 388, 472, 388, 468, 1248, 472, 388, 468, 392, 468, 392, 468, 388, 468, 392, 468, 388, 472, 416, 444, 392, 472, 388, 472, 1264, 448, 1264, 444, 388, 472, 392, 468, 388, 472, 388, 468, 396, 468, 392, 468, 416, 444, 1268, 444, 1264, 448, 1264, 444, 1244, 468, 1268, 444, 392, 468, 
When I now try to send the signal back, the AC does not respond. Then I applied this script to clean the signal:[Link removed by Admin] But still no response.

Do you have any further ideas? Thanks in advance for your help.

The signal you posted decodes successfully in AnalysIR as a Panasonic 216 bit AC signal.

If you have a copy of analysIR, You can automatically clean the signal via the PowerTools menu. It will also generate the C code to send using IRremote , IRLib (or LIRC conf file) via Batch Export menu option.

If not just change the values to 3500,1750435,1300 and it should work OK.

Otherwise there may be an issue with your IR emitter circuit.

Not surprising, The algorithm used is quite poor for IR signals and is likely to cause more issues than it solves.
PS: I will remove the link to that script to save others the hassle.

Ok, thanks for your ideas!

I will clean the signal with the given values and otherwise try to improve my IR-circuit.
