Hello Robman,

Hi Yesok,
I just started looking at your latest zip file and I notice that the learns in the "mode" file are still un-labelled

The file is here https://www.hifi-remote.com/forums/dload ... le_id=4394.

The following functions are labelled the same but have different codes. Could you test some of the button pairs to see if they really do exactly the same thing. There are more pairs than I've listed here.

1) Air Clean - Off

file 1, TV/vol-

2) Cool mode - turbo

file 1, TV/7

3) Cool mode - far

Hello Robman,

I have recheked my test result as follows. The buttons really perform listed function. Please note the added labels for mode and decode of Girder for the original Samsung Air Conditioner Remote.

Here are some buttons that appear to have the exact same signals, yet you list different functions for them. Could you see if these buttons really do perform all of the listed functions.

FUNCTION 1:
cool mode - normal (file 1, TV/6)
fan - high (file 3, DVD/3) - Girder decode 7305055D40F4
mode - COOL (file 4, DVD/4) - Girder decode 7300050D45F4

FUNCTION 2:
deflector left/right off (file 2, VCR/left)
fan - low (file 3, AUX/1)

FUNCTION 3:
cool mode - normal (file 1, TV/3)
fan - high (file 3, AUX/3)
mode - COOL(file 4, TV/4) - Girder decode 7300050D45F4

here's the file cross-ref:
1 = URC-9910B01-Samsung_AirCon-L-CoolMode-AirClean-20070327-a.ir
2 = URC-9910B01-Samsung_AirCon-L-Deflector-20070327-a.ir
3 = URC-9910B01-Samsung_AirCon-L-Fan-20070327-a.ir

Hello Robman,

I have rechecked the code as follows. They do perform listed functions.

Many thanks for your support.

So you've supplied the label for one of the "mode" buttons (ie, button 4 = COOL) but what about the other 3 mode buttons?

1 =
2 =
3 =
4 = cool

Here is the answer.

1 = Auto
2 = DeHumidify
3 = Fan
4 = Cool

I guess the Samsung Air Conditioner's IR receiver is quite unintelligent, in that it may only recognize several basic commands(such as Mode) , located in a fixed or rotating portion of a long IR pattern, and up/down traverse of prededfined sequences based on one or more direction bit(s).

The IR remote may send different IR patterns on each key press just to prevent unwanted fast repeation of same key presses. Or it is a safety feature to guard from a playful child.

FYI Samsung used to license technology from major Japanese electronic companies such as NEC, Sanyo, etc.

Hope you are making big progress.

Thanks again for your time and effort.

I have created an upgrade for you to test. At this point, I haven't tried programming any relationship between the data bytes, so there are 6 bytes of variable data per button, which means the upgrade is going to be BIG.

Thanks for the upgrade.
I will send you the test result tomorrow.

In the code, I do not see Power Off.
Please have a look.

Could you make the upgrade working with RM?

[The Robman]

You said that the POWER OFF learns didn't work, so I didn't include that button. It looks like the power off signal is too long to be learned using a remote, so your best option would be to use a CaptureIR device.

Hello Robman,

You said that the POWER OFF lerans didn't work, so I didn't include that button. It looks like the power off signal is too long to be learned using a remote, so your best option would be to use a CaptureIR device.

Could you tell me more about how to use CaptureIR to get Power Off signal, and what data you need?

Yesok

[The Robman]

Sorry, I can't do CaptureIR questions, I would have to refer you to John Fine for those. Bottom line, you would need to build a captureIR device first.

Did you have any luck using the upgrade that I created?

Yes, I need to build the CaptureIR device first.

Yes. All buttons , except temp up1(vol +) and temp down1(vol -) works fine.
I will test again with temp up2, 3, 4 and temp down 2, 3, 4 tomorrow.

One question. When I assigned temp up and down buttons to keys with @(such as @sleep) under KM, and copy and paste upgrade code to IR, IR complains about illegal characters in input. It does not complain when I assign those functions to keys without @. What is making such difference?

Is the KM upgrade code incompatible with RM?

The difference is that KM or RM will need to generate keymoves for those buttons, but that doesn't explain why IR is rejecting the keymove data. What verson of IR are you using? Maybe if you were to cut and paste the upgrade code here, we might spot what's going on. I just tried it myself and IR didn't object to the keymove data, here's the block of code that I generated...

Hello Robman,

I am using IR 7.00(Beta3).

Maybe if you were to cut and paste the upgrade code here, we might spot what's going on. I just tried it myself and IR didn't object to the keymove data, here's the block of code that I generated...

Here is the screen capture of IR with your code cut and pasted(see https://www.hifi-remote.com/forums/dload ... le_id=4420).

I suspect delimeters(such as <<. >>, |, etc.) are causing the problem. Since Korean Characters are based on 2 byte character codes, when it is mixed with a certain ASCII byte and/or non-printing characters we see unwanted weird results.

An Asian language processing expert may give you better explanations and solutions.

BTW is your upgrade compatible with RM?

Hello Robman,

I have uploaded CaptureIR captured signals for Power Off/On( see https://www.hifi-remote.com/forums/dload ... le_id=4421).

Could you tell me the next steps to follow?

With Power Off decoded, I will make combined test with the Air Conditioner.
