Topic: Panasonic Remote Control IR codes in hex (Read 11650 times) previous topic - next topic

GaganP

I have a Panasonic Viera 42AS610 and I want to use an Arduino Mega 2560 for cloning the remote. :)

I got the code from: http://files.remotecentral.com/library/3-1/panasonic/hdtv/index.html  :)

Although  this code may not work for my TV, I still want to try it. 

As a newbie(got to know about arduino only 2 months ago) I do not know the pronto hex format.There are very good websites explaining them, I didn't understand even the head or tail of it.  :smiley-confuse:

I need help converting

0000 0071 0000 0032 0080 003f 0010 0010 0010 0030 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0030 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0030 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0030 0010 0030 0010 0030 0010 0030 0010 0030 0010 0030 0010 0010 0010 0010 0010 0030 0010 0030 0010 0030 0010 0030 0010 0030 0010 0030 0010 0010 0010 0030 0010 0a98

to a format like

[255, 136, 130, 34](Not exact code but copied from http://www.zovirl.com/2008/11/12/building-a-universal-remote-with-an-arduino/)

Gee... nobody answered you?

I'm working on an IR remote project and can probably help you out.

The data file in your quote consists of pulse counts of IR energy to make up a remote code.

An IR remote command is usually:

(1) A header - a long burst of IR pulses used solely to set the AGC of the IR receiver on the TV
(2) A "Mark" pulse, consisting of enough IR pulses (at 38 or 40 khz) to last around 1200 milliseconds.
(3) A "Space" pulse consisting of enough IR pulses to last around 600 milliseconds (i.e. 1/2 of a Mark).

Note: A header is usually twice as long as a Mark.

Next, the data is encoded bit for bit. A Mark-Space (that is, Long-Short) means binary "1" and a Space-Space (short-short) means binary "0".

Some devices (like Panasonic HA HA!) use both an address and a data packet in the command.  So, let's decode your data above and see what it says:

* The first 4 numbers look like junk.
* The 80, 3F is probably the Header.
* Now, let's see what we have:

0080 003f - header

0010 0010 - 0 4
0010 0010 - 1
0010 0010 - 0
0010 0010 - 0

0010 0010 - 0 0
0010 0010 - 0

0010 0010 - 0

0010 0010 - 0 4

0010 0010 - 0
0010 0010 - 0

0010 0010 - 0 0
0010 0010 - 0
0010 0010 - 0
0010 0010 - 0

0010 0010 - 0 1
0010 0010 - 0
0010 0010 - 0
0010 0010 - 1

0010 0010 - 0 0
0010 0010 - 0
0010 0010 - 0
0010 0010 - 0

0010 0010 - 0 0
0010 0010 - 0
0010 0010 - 0
0010 0010 - 0

0010 0010 - 1 F
0010 0010 - 1
0010 0010 - 1
0010 0010 - 1

0010 0010 - 1 C
0010 0010 - 1
0010 0010 - 0
0010 0010 - 0

0010 0010 - 1 F
0010 0010 - 1
0010 0010 - 1
0010 0010 - 1

0010 0010 - 1 D
0010 0010 - 1
0010 0010 - 0
0010 0010 - 1

0010 0a98 - junk at the end

So, you see? The data consists of a 16 bit address 0x4004 and a 32 bit command of 0x0100FCFD.

Lastly, the numbers themselves are cycle counts (at 40 khz probably). At 40 khz, each cycle is 25 microseconds (1/40khz). So the pulse widths are:

Header = 0x80 = 128, 128 * 25 = 3200 microseconds
Header 0x3F = 63, 63 * 25 = 1575 (most probably supposed to be 0x40, 1600 microseconds)
Mark bit = 0x10 = 16, 16 * 25 = 400 microseconds
Data Mark = 0x30 = 48, 48 * 25 = 1200 microseconds
Data Space = 0x10 = 16, 16 * 25 = 400 microseconds

Now, realize that those timings were probably obtained by someone's IR analyzer and could be a little bit off. USUALLY you will find that headers, marks, spaces, etc... are all integer multiples of the carrier frequency. In fact, I KNOW for sure that Panasonic uses 500 microseconds for the Mark bit, not 400, so it's probably an error on the part of the person taking the data.

Great, so now what do you DO with all of this? Well, take a look at the source from my IR transmitter. It uses a timer interrupt to generate the 40 khz and another interrupt to allow the processor to sleep, then wake up when the button is pressed, send out the IR code, then go back to sleep (i.e. no power switch needed).

This should be enough to get you started. Note that this code is for an ATTiny processor, so if you want to use it on a 328P (Uno) or a Mega2560, you will have to change a few register names and/or bits as required... but at least it's a starting point. In fact, so this message board doesn't prohibit me from posting so much text, I'll put the source in the next post.

Very Sorry for my vvveeerrryyy late reply, Thanks a lot. Now I finally understand it. I thought no one had replied because i do not check my mail often. :smiley-slim:

Actually I finally gave up a week after I had posted the question. But now i am thinking to revive the project. Any errors, I will start a new topic. So, think of this post as solved!!!!!
 
Thank You
