Hello
I have a 3 buttons remote to command my Window Blind.
I've learn the IR signal, it works ok, and tell me about a Old Panasonic Protocol.
I would like to find the protocol of this device to find some other codes
like step by step up/down, slowest up/down ...

here are my learned signals :
UP :
31 27 28 01 03 03 00 CF 33 2F 00 CF 02 74 02 74
00 CB 30 11 21 12 11 11 12 21 21 21 12 21 10 11
21 12 11 11 12 21 21 21 12 21 10

Ok :
35 27 28 01 04 03 00 D0 33 2E 00 D0 02 73 02 76
00 C8 30 21 21 12 11 11 12 21 21 21 12 11 20 21
21 12 11 11 12 21 21 21 12 11 20

Down :
32 27 28 01 04 03 02 76 31 84 00 D0 02 73 02 76
00 C8 30 12 21 12 11 11 12 21 21 21 12 22 10 12
21 12 11 11 12 21 21 21 12 22 10

thank you.

Just FYI, it's easier for you and us if you just load the IR file with the learns in it, rather than cut & pasting the hex. Doing it this way, I have to cut and paste the hex back into an IR file into order to decode the signals.

Anyway, here's an upgrade for you to try...

thank you very much Rob.

I've tried this upgrade on my URC-8820 : nothing's working

I've tried it on my URC-39730 : the stop key works well,
whereas the up and down keys work 1 time, and not some other times,
likely it did not send the same signal each time you press the same key.

So, i post a new ir file, where i learn 3 times the up key (on 1 2 3 keys),
3 times the stop (on 4 5 6 keys), and same for down key (on 7 8 9 keys).

thanks again.

PB doesn't generate the right code for HCS08 remotes. I thought I'd compensated for that manually but it appears that I didn't make the right correction, so we'll need to wait for the next version of PB to get the right code for the URC-8820.

You had good instincts regarding learning the same button many times as that's how we find toggle bits, but your new set of learns show that there aren't any in this signal.

Here's the binary for your learns, where 1= +400 -1200 and 0= +1200 -400 ...

Code: Select all

UP
1 = 110110111110001111010111 -25000 110110111110001111010111 -25000
2 = 110110111110001111010111 -25000 110110111110001111010111 -25000
3 = 110110111110001111010111 -25000 110110111110001111010111 -25000

STOP
4 = 010110111110001111011101 -25000 010110111110001111011101 -25000
5 = 010110111110001111011101 -25000 010110111110001111011101 -25000
6 = 010110111110001111011101 -25000 010110111110001111011101 -25000

DOWN
7 = 100110111110001111010010 -25000 100110111110001111010010 -25000
8 = 100110111110001111010010 -25000 100110111110001111010010 -25000
9 = 100110111110001111010010 -25000 100110111110001111010010 -25000

As I really think the same key don't give the same code, i do a new code sequence learning, coresponding the one I tryed. My mistake was you never press the same key few times, because when the blind start going up, if you press up again, nothing new will append.

So I learned the keys in this new order, where keys work only some times on my URC-39730 :

1-Up 2-Stop 3-Down 4-Stop 5-Up 6-Stop 7-Down 8-Stop 9-Up 0-Stop

http://www.hifi-remote.com/forums/dload ... le_id=6006

In all cases, the stop key stops the blind.

Rob, I am rigth ?

As you can see, the signal doesn't change.

How are you learning these signals, are you pressing and holding the Velox button down? If so, try a short press because it's possible that the remote is sending something different when you release the button.

Also, do the learned signals work reliably? After all, I am replicating the learns, so if they don't work, my upgrade won't work either.

You were right. my learned codes doesn't work each times. In fact, the problem appends with the original remote, and for up and down keys, to be shure the blind starts, I have to push the key for a longer time.

So, I tried again your upgrade, but it just send short signal, even if i keep the key down.

Is it possible to build an upgrade that send a signal as long as the key is pressed ?

I uploaded some long learned signal here, if needed:

Thanks again Rob.

According to your latest learns, the UP and DOWN buttons repeat, but the STOP button does not, however I can't imagine that it would matter if it did repeat. Also, there is a longer gap after every 2nd repeat. I don't know if this is needed, so I've modified the upgrade to not do this as it makes it simpler.

All keys are working, pushing a long time, but the time for the motor of the blind to start is much bigger than the original remote (nearly 1 seconde after pressing key). I gess the gab after the 2nd repeat about this.
How ever, the stop key, witch was ok in the first update, still stop the blind, but now after a few time (nearly 1 seconde).
Maybe is it perfectible.

Is there some article for me to understand the assembly code of the protocols you wrote ?

Post by **The Robman** » Mon Dec 08, 2008 4:04 pm

I haven't used any assembler on this one yet, I've been able to do it all using the built in IR engine (and I created the executor using the Protocol Builder spreadsheet).

In order to get the long delay after every 2nd send, I would need to use assembler.

I will have a look to the Protocol Builder spreadsheet.

Thank you, Rob.
