grazie, sistemato.
approfitto per spiegare nel dettaglio cosa ho fatto (non chiedetemi di tradurlo, tanto le immagini parlano da sole):
I almost found a very easy method for ALL to be able to create their own IR Remote files.
I used a single
standard IR LED:
I simply connected it to
microphone input if my audio card, a VIA AC '97, using a standard headphone cable
Look at the pictures.
Pick an headphone cable and cut its ending:
Separate the two small wires which compose the cable and remove their cover; you'l see any wire is surrounded by very thin copper wires; "pack" them up and join all of them together, from both wires:
Now you should attach the Led to the "naked" wire and to ONE of the remaining wires; don't care which one, anyone is good.
To attach the led, you can use a "proper method" like the one in picturesm, or any method you lke:
Just be sure the two wires connected to the two pins of the led are SEPARATED.
Now plug the cable into MICropohone port on your sound card and put the remote in front of the led:
Now you need a freeware audio recorder like
Audacity.
Start the program, start recording, press a button on the remote, and you should see "something" on the screen; just zoom in, and you should see something like this:
This is the binary code of the button you just pressed.
Now comes the bad part: how to convert these data to LIRC standatrd format?!?
I have some data for comparison:
LG DVD Recorder RH 255:
PLAY :
Corresponds to LIRC code 0x8C73 = 1000 1100 0111 0011
STOP:
Corresponds to LIRC code 0x9C63 = 1001 1100 0110 0011
I don't know how to pass from waveform to LIRC code, I just sampled a remote of which I already had the LIRC file.
Figuring out how to pass from waveform to LIRC code should allow virtually ANYBODY to "clone" its remote!
