@Zibri: note that IrMaster allows you to choose between "stereo" and mono.

Hmm ok I found the option, I don't see the phase inversion flag for stereo waveforms. You should add one.
The "stereo" signal comes with the channels in opposite phases. (As can be read in the documentation or the popup ...

I just rechecked. Nothing.
VolUp and VolDown don't work with the generated wavs on an iPad

Another strange fact:
the vol up I posted works on my samsung 55F8000 even if it decodes as

protocol = NECx, device = 7, subdevice = 7, obc = 7

Vol down is:

protocol = NECx, device = 7, subdevice = 7, obc = 11

But in IR802, I have Vol+ OBC 1F and Vol- OBC 2F and protocol necX2.

I'm not sure ...

hmm thanks barf, I used a java disassembler to look at IRPMASTER library.
WoW. Too complex for me!
About html5 and javascript sound generation that's pretty simple.
Ok then. I will build a few dongles with the other schematic.
Anyway I suggest to generate 44khz waveforms and not 48khz since many ...

why do you think it's BAD??

Not sure why Kevin thinks it is bad, but myself I am not so sure that essentially shorting your audio jack is good for its health.

xnappo

Well.. they're both shorts. In my case between channels and ground (as it should be), In the other case between channels and ...

Bad info, bad code and bad dongle design there.

infos: probably bad.
code: I don't know.

dongle: why is it bad?
do you prefer this one?

With this design the voltage is doubled but drives 2 leds.
In the design I proposed, the voltage is normal ...

In the above picture you can sse that the leds are inverted.
So the wav file needed is just a mono wav (same signal on both channels)

Every led flashes "half" of the wave and both together get the full wave.

Very nice program, but please include another mode.
I see left and right channels are phase inverted.
This can work with single led audio jack.

Phase inversion and 2 LEDs are required for proper operation. The theory is explained here: http://www.compendiumarcana.com/iraudio

I used a dual ...

Yep.. thanks.. I posted there too.
This dongle is even cheaper than that one.
And I tested it.. it works from 4 meters using an iPad.
Dual phase inverted leds is the key

Here is a simple program to convert pronto hex to audio.

44.1 kHz and 16 bit options are provided for portable music players that don't like 48 kHz or/and 8 bit wav files.

hmm.. what we need is only a pronto to wav program.

something like this:
http://rtfms.com/wp-content/rtfms-com/pronto_code_to_wav.py

But that should be implemented in RM803 or irmaster.

What I would like to do is to code an IR generator in HTML5 and to code a good online universal remote which ...

Zibri

Hello again good people!

I had a look at this simple project:
http://rtfms.com/episode-4-turn-your-iphoneandroid-mac-pc-player-etc-into-a-universal-remote.htm

I ordered some leds and some jacks and I'm building some of them.

I wonder if any of the programs in this forum archive can generate WAV ...

Zibri

As I said.. I was just curious. I don't even have that remote

I have a gorgeous URC 7560

Zibri

just wondering.. maybe also this kind of remotes is hackable/dumpable
