Thanks for taking the time to answer Barf.

I read the SB-project page on NEC1. But as stated before in this thread, I'm only a novice in this field. I really do miss the basic knowledge. So I do not really understand your answer either. But maybe I will someday...
In spite of that, I'll continue to follow this thread. Possibly learn a bit, and help if I can.

Great day, Anders

I use this online converter: [Link: binaryhexconverter.com]

I use this Hex to decimal converter.

To my knowledge, the protocol we call NEC1 is specified in official documents. It is also described in a number of places on the Internet, for example [Link: sbprojects.com] . (I even think that the firm NEC (now called Renesas) asks for a license fee if you implement it in a commercial product with D != 0.)

The procotol NEC1 contains 32 "payload" bits, which can be decomposed into four bytes. First one is device address, called D by IrScrutinizer and DecodeIR. The second one was originally just the (one-) complement of the first, but as more "addresses" were sought, it aquired its owm "life" as "subdevice", S. The third byte is the command number, F. The forth byte the complement of the third, although some manufacturers (Yamaha, possibly others) has used it differently. Note that by convention AND specification, these bytes are interpreted least significant bit first.

Some projects interpret the payload bits differently. For example Arduino-IRremote [Link: github.com] considers the number of bits variable (up to 32) and lumps them all into one number, interpreted most-significant-bit-first.

Why Lyngdorf selected their format you have to ask them. Possibly the last two "numbers" of the "short pronto form"?

I have put a file in Girr format (can be directly read into IrScrutinizer, and then transformed to other formats) here: [Link: raw.githubusercontent.com]

Hello,

Can you please tell me in easy way if it possible to convert Lyngdorf NEC1 code list provided by them to 5digit format to manually program buttons with One for All remote?

Do you only need to convert hex values to decimal or you must use IRScrutinizer and do some more advanced conversion?

Jack,

you should not open three different threads,,,

It is not clear what the manufacturer means by

Volume Up: 0x10EF, 0x1AE5

namely how this transforms to the NEC parameters. Let's guess that this means that (notation as per above) D=0x10, S=0xEF,F=0x1A.

I hand edited the command list for this , and imported in IrScrutinizer. IrScrutinizer does not compute EFC and EFC5, since there is another program that does this, RMDU [Link: sourceforge.net] . That program is very useful for programming remotes like your URC-7935. So I exported the data from IrScutinizer as a Girr file [Link: harctoolbox.org], and loaded it into RMIR. This, this among other things, computes EFC5s. The resulting file is this one: [Link: harctoolbox.org]. But is can also download the whole shebang into the remote. For more information on RMIR, see the JP1-forum [Link: hifi-remote.com].

Accept my apologies, I am just desperate trying to find a way how to use a universal remote instead of 100EUR Lyngord remote...

Unfortunately, the only thing Lyngdorf does is providing the full NEC1 codes list in format as on their website and as I quoted in other topics: [Link: lyngdorf.steinwaylyngdorf.com]

I am gratefull to you for creating a file but how do I upload it into Streamer Remote? Do you mean updating the internal remote code list database?
