Hi

I don't know why I can't decode this ir files

please help me transfer to remote master's file.

Thanks,

Fairly simple protocol...here's the info for someone to make an ugrade:

First, the bits:

Code: Select all

Lead In = +3648 -1810
Lead Out = +575 -54164
0 = +576 -1112
1 = +572 - 550

There are three parameters (device, subdevice, whatever)...all of these signals are:

Code: Select all

A = 00011101 = 29
B = 01111101 = 125
C = 11011101 = 221

The format is: LeadIn, A, OBC, B, LeadIn, C, ~OBC, LeadOut

To make the numbers for the OBCs go in nice sequences, I interpreted them as least significant bit first:

Code: Select all

Mute    ==  OBC = 238  ==  LI A 01110111 B LI C 10001000 LO 
Info    ==  OBC = 228  ==  LI A 00100111 B LI C 11011000 LO 
Return  ==  OBC = 227  ==  LI A 11000111 B LI C 00111000 LO 
Exit    ==  OBC = 226  ==  LI A 01000111 B LI C 10111000 LO 
Up      ==  OBC = 225  ==  LI A 10000111 B LI C 01111000 LO 
Down    ==  OBC = 224  ==  LI A 00000111 B LI C 11111000 LO 
Left    ==  OBC = 223  ==  LI A 11111011 B LI C 00000100 LO 
Right   ==  OBC = 222  ==  LI A 01111011 B LI C 10000100 LO 
Select  ==  OBC = 221  ==  LI A 10111011 B LI C 01000100 LO 
VOL+    ==  OBC = 236  ==  LI A 00110111 B LI C 11001000 LO 
VOL-    ==  OBC = 235  ==  LI A 11010111 B LI C 00101000 LO 
Guide   ==  OBC = 231  ==  LI A 11100111 B LI C 00011000 LO 
Page+   ==  OBC = 234  ==  LI A 01010111 B LI C 10101000 LO 
Page-   ==  OBC = 233  ==  LI A 10010111 B LI C 01101000 LO 
Red     ==  OBC = 213  ==  LI A 10101011 B LI C 01010100 LO 
Green   ==  OBC = 212  ==  LI A 00101011 B LI C 11010100 LO 
Yellow  ==  OBC = 211  ==  LI A 11001011 B LI C 00110100 LO 
Blue    ==  OBC = 210  ==  LI A 01001011 B LI C 10110100 LO 
0       ==  OBC = 209  ==  LI A 10001011 B LI C 01110100 LO 
1       ==  OBC = 208  ==  LI A 00001011 B LI C 11110100 LO 
2       ==  OBC = 207  ==  LI A 11110011 B LI C 00001100 LO 
3       ==  OBC = 206  ==  LI A 01110011 B LI C 10001100 LO 
4       ==  OBC = 205  ==  LI A 10110011 B LI C 01001100 LO 
5       ==  OBC = 204  ==  LI A 00110011 B LI C 11001100 LO 
6       ==  OBC = 203  ==  LI A 11010011 B LI C 00101100 LO 
7       ==  OBC = 202  ==  LI A 01010011 B LI C 10101100 LO 
8       ==  OBC = 201  ==  LI A 10010011 B LI C 01101100 LO 
9       ==  OBC = 200  ==  LI A 00010011 B LI C 11101100 LO

Only some of the signals were detected as repeating, but all of them had the same repeat sequence, and even the ones not detected as repeating have the repeat sequence at the end...so I think it's safe to say they all just send that as the repeat:

Code: Select all

Repeat = +3648 -3656; +576 -100474

I believe this is the same set of signals as these.
The learns in the linked thread were taken with a Widget, and so I believe the indicated toggle bits are correct. I think taking the longer off time as indicating a one (typical of gap type IR protocols) gives a simpler set of OBCs.

Hmm, I didn't see the older post. Has there been any active work on these? Like an attempt that just needs to be debugged, or are we starting totally from scratch?

Gee you don't use this stuff in a while and you get a bit rusty. I'm having trouble with the Dittos. I got the data frame with the second LI sending out, but the flags for the for the "ditto" repeats with the LI, One-On, are giving me a problem. I suppose you don't need the dittos for the slingbox, but I'd like to make it work right for our remotes.

jkgtw,

Hi jkgtw, sorry I haven't gotten back to you. We had a holiday weekend, and I've been busy with my new Chinese Toy. Walmart started selling Hisense Sero 7 Pro Tablets and learning how to use that has been my first priority.

I haven't had a chance to work on the repeat portion, even though 3fg was kind enough to send me a ditto repeat sample. The chance that you will need a repeat on a slingbox is pretty slim. Give this a try and see if it works for you.

Hi all

Sorry for the late reply.
I'll test it in next few days, if successful I will let you know.
Thank you very much!
