I have been working to decode the raw IR codes for my panasonic PT-45LC12 lcd projection tv. I want to try and get discrete codes for each source (video1, component1, etc) and for each picture mode (full, just, zoom, normal). The codes in the files section of this website do not work for these functions (power on/off did work but source and screen size did not), so I began to analyze the codes I have learned from the factory remote. So far, here is what I have figured out.

first 4 words = preamble = 0000 0070 0000 0032
next 2 words = lead in = 0084 0041

next 25 words appears to be a device address. They are the same for all codes to this tv that I learned from the oem remote. I don't know which represents 1 or 0, but let's assume 0011 0010 represents 0, and 0011 0030 represents 1, the device code is: 0100000000000100000000010

next 23 words I am guessing determines which button is being pressed. I am in the middle of compiling a list of these codes for all the buttons I have learned, and then plan to experiment by altering these 23 words.

next 2 words = lead out = 0011 0AAB

If anyone has already done this and has some codes they would like to share, please let me know and I'll give them a shot.

I went through all the codes on my oem remote and here is what I found:

each raw IR code is compromised of:
4 words preamble = 0000 0070 0000 0032
2 words lead in = 0084 0041
25 word pairs = device id (lsb) 0100000000000100000000010 (msb)
23 word pairs = button codes (see below)
2 words lead out = 0011 0AAB

where the button code words are made of:
7 word pairs = all 0s (0011 0010 7 times)
7 word pairs = button code shown below
1 word pair = 0 (0011 0010)
7 word pairs = repeat the button code
1 word pair = 1 (0011 0030)

Below are the button codes with the byte order reversed so that it is in typical binary order with msb on the left and lsb on the right.

(decimal value) - button - binary

(126) - bbe - 1 1111110 0 1111110 0000000

So for example, a complete raw IR code for the 1 button would be:

preamble
0000 0070 0000 0032

lead in
0084 0041

device code
0011 0010 0011 0030 0011 0010 0011 0010 0011 0010 0011 0010 0011 0010 0011 0010 0011 0010 0011 0010 0011 0010 0011 0010 0011 0010 0011 0030 0011 0010 0011 0010 0011 0010 0011 0010 0011 0010 0011 0010 0011 0010 0011 0010 0011 0010 0011 0030 0011 0010

7 repeated 0's
0011 0010 0011 0010 0011 0010 0011 0010 0011 0010 0011 0010 0011 0010

button code
0011 0010 0011 0010 0011 0010 0011 0010 0011 0030 0011 0010 0011 0010

one 0
0011 0010

button code
0011 0010 0011 0010 0011 0010 0011 0010 0011 0030 0011 0010 0011 0010

one 1
0011 0030

lead out
0011 0AAB

Now that I've got that down, it's time to try some of the in between values and see what I can find. Has anyone gone though testing like this? I Can't mess up my TV by sending it any of the in between codes can I?

I found the discrete for video1 is button code = 5. I also found that button code 6 flashes the picture adjust menu briefly and button code 7 flashes the audio adjust menu briefly.

I have gone through button codes 1-33 so far and the only useful one so far is for video 1. The full pronto hex raw IR code is:

0000 0070 0000 0032 0084 0041 0011 0010 0011 0030 0011 0010 0011 0010 0011 0010 0011 0010 0011 0010 0011 0010 0011 0010 0011 0010 0011 0010 0011 0010 0011 0010 0011 0030 0011 0010 0011 0010 0011 0010 0011 0010 0011 0010 0011 0010 0011 0010 0011 0010 0011 0010 0011 0030 0011 0010 0011 0010 0011 0010 0011 0010 0011 0010 0011 0010 0011 0010 0011 0010 0011 0030 0011 0010 0011 0030 0011 0010 0011 0010 0011 0010 0011 0010 0011 0010 0011 0030 0011 0010 0011 0030 0011 0010 0011 0010 0011 0010 0011 0010 0011 0030 0011 0AAB

Doh I found that the button code 5 I list above is actually just a source button. It cycles through all the inputs, not direct to line 1.

I guess the guys in the discrete forum have pretty much been through this and could not find working discrete source buttons for these remotes :(

Heyy.. how do I send these pronto hex codes using IRsend in arduino?? The sendRAW command accepts only octal digits ..does anyone know an alternative way? I am currently trying to make it work for panasonic.. please help...
