Having tough time grasping IR codes read

realseth · November 7, 2022, 12:19pm

Attempting to read IR codes my Fujitsu AR-RCF1U remote uses for a range of temperatures, different air and fan settings.

Using File->Exanples->IRremote->ReceiveDemo

/*
 * ReceiveDemo.cpp
 *
 * Demonstrates receiving IR codes with the IRremote library and the use of the Arduino tone() function with this library.
 * If debug button is pressed (pin connected to ground) a long output is generated.

The idea was to record all the codes for different temperatures in a range, then noticed after changing the air settings from Auto, Cool, & Heat, different codes were given for previously recorded temperatures. My thought, "ok, maybe the remote gives a unique code depending on the different settings", then I tested setting the temperature back and forth before 76 & 78 and noticed getting different codes just with that.

What's going on, what am I missing, doing wrong, or not grasping?

I would start by converting the raw data to data bits.

It looks like the + values are all close together (300 to 500) so they can be ignored. The - values are either in the 300 to 500 range or about 1200. I would count anything below 1000 as '0' and everything about 1000 to be '1'.

This will reduce the values to, for example:

0010
1000
1100
0110
0000
0000
0000
1000
0000
1000
0111
1111
1001
0000
0000
1100
0000
0001
0000
0000
0000
0000
0000
0000
0000
0000
0000
0000
0000
0100
0000
1100

Then you can reduce those groups of 4 bits to hexadecimal:
28C60008087F900C010000000000040C

That will make it much easier to compare messages. Perhaps there is a sequence number that causes each message to be different.

The codes for an air conditioner remote control are much more complicated than those for a TV or audio system, for example. When a remote sends a code to an air conditioner, it contains EVERYTHING - hot/cold mode, set temperature, fan power, etc. There are separate groups of bits that are for each thing and usually have a few bits to check the integrity of the data - a checksum.

Hi @realseth, and greetings to the others who helped in this post

Did it work for you with your off/on example?

Protocol=PulseDistance Raw-Data=0xFD0210 56 bits LSB first
Send with:
    uint32_t tRawData[]={0x10006314, 0xFD0210};
    IrSender.sendPulseDistanceWidthFromArray(38, 3200, 1650, 400, 1200, 400, 400, &tRawData[0], 56, PROTOCOL_IS_LSB_FIRST, <millisofRepeatPeriod>, <numberOfRepeats>);

I too have an air conditioner that I need to turn on or off, but in my case I get 3 messages like this

and I can't get it in any way and I don't know why, I am using the SimpleSender example

very interesting my friend

I would like to apply that to my example, but I still don't understand it very well.
