Here's a new one I can't get decoded. It appears to follow something resembling the NEC2 format, but there's a burst pair between the complement. DecodeIR can't do a thing with it, but ExchangeIR produced this IRP notation.

I imported these codes into IR and then converted them to binary (using 0= +400 -400 and 1= +400 -800) and got the following:
+1200 -800 00000010 11111101 +800 -800 00000001 11111110 +400 -14000
+1200 -800 00000010 11111101 +800 -800 00000010 11111101 +400 -14000
+1200 -800 00000010 11111101 +800 -800 00000010 11111101 +400 -14000
So, I do see the extra "+800 -800" pair that you were talking about. We call this a "mid frame burst pair". Unfortunately, I don't think there's any way to generate that particular mid-frame burst pair using the IR engine, so we would have to generate the signal by hand (ie, we'd need to write the assembler). _________________ Rob

Just curious - has it ever been the case that we have found an error in the protocol generation of the remote we are trying to duplicate? I mean - maybe it is a mistake and isn't really needed?

No, I don't think we've ever found an error, but sometimes we find that the signal doesn't need to be as exact as the learns might imply.
I can never remember the two ways that we can generate mid frame burst pairs, so I need to document it and post it somewhere, but if I recall, one way just repeats the leadin pair and the other way combines two partial pairs (but I forget which). _________________ Rob

Yeah, that's what I came up with too when I broke it down last time I messed with it in November. This was my first attempt at learning decodes. Like you said, there's not a lot of documentation on the mid frame bursts that I could find when I played with these codes. I tried PB, but I'm not an expert there. I couldn't figure out the midframe burst settings.
I don't actually have the piece of equipment to test the signal (backed out on the purchase). I did try to build an upgrade in the process. It looks like an interest protocol. If work picks up again, I may end up getting the video switcher after all. And I know you guys like challenges. |

Do you have a complete set of learns? _________________ Rob

Just the Pronto Hex of the 64 or so codes (8X8 matrix) |

Could you post them please. Or better yet, use the new IR functionality to add them all to an IR file and post that. _________________ Rob

Is there a batch processor in the new IR to import more than one at a time? |

I just discovered there are 256 codes for this device. Apparently you can stack 8 component inputs to 32 component outputs if you have 4 units.
I built an IR file with the first two outputs and the associated 8 inputs (16 total learns from the CCF).
I found the manufacturers file that has a format more processed than a CCF. It has the burst pairs listed first and then how the pairs are sent out. It's in a format more usable to us (binary type). I'm sure once we establish the executor, the rest of the 240 codes can easily be figured by a simple binary to hex conversion.
here's what I figured...
~0000OUTPUT1 INPUT1$
:00000920000092 <---Burst Pair 0 timings (00 below)
:00000920000184 <---Burst Pair 1 timings (01 below)
:00002760000184 <---Lead IN Burst Pair (02 below)
:00001840000184 <---Mid Frame Burst Pair (03 below)
:00000920003226 <---Lead Out Burst Pair (04 below)
^
:00460000 Frequency ~ 40.2kHz
^
:02 <---Lead IN Burst Pair
:00 :00 :00 :00 :00 :00 :01 :00 data
:01 :01 :01 :01 :01 :01 :00 :01 data complement
:03 <---Mid Frame Burst Pair
:00 :00 :00 :00 :00 :00 :00 :00 repeated
:01 :01 :01 :01 :01 :01 :01 :01
:04 <---Lead Out Burst Pair
The italicized comments are my notes. |

Thanks Rob.
How does it change for the HCS08 processors? I'm sure the entry points change for the mid frame burst execution on the HCS08. That's where I got stuck earlier. |

I've just updated the files to include the HCS08 protocol code too.
Keep in mind that this is all experimental, I don't have any proof that it will work yet. _________________ Rob

It's a start though. |
