to be honest, I hadn't noticed your reply. Just in case someone else can get to it before me, here's a helpful link to the file captured rc5.txt

Do these learned signals actually work? They sure are weird looking.

[The Robman]

Hey Tradcli,
Could you confirm that these learns actually work. Also, could you confirm that you're holding down the source button for the duration. Finally, could you re-learn the CD-6 button, there's something funky going on with that one. In fact, if you could, could you re-learn all the buttons, just to make sure they look the same each time.

There appears to be four burst pairs in use here:

pair-a = +714 -5330
pair-b = +576 -130494
pair-c = +582 -31892
pair-d = +576 -22360

abd the buttons use the pairs like this...
cd2 = a b
cd1 = a c a b
cd3 = a d a b
cd4 = a c a b a b
cd5 = a c a b a b
cd6 = a d b a d a

I learned the same signal to all six buttons. You are right, button 6 is a little eratic and should be discarded. All six buttons do work, but key 2 is the cleanest learn of the signal.

Where I want to go is to have something that has a one second delay, then the command on button 1, A two second delay then the command on button 2, etc with button 0 sending just the command.

I can do the grunt work with KM if I have the basics. (the learned signal and a method of creating the delay.)

Thanks,

Tradcli

Now that I know this is the same button learned to each button, that certainly helps. However, I'm still not clear on how this signal should repeat. When you do the learning process, are you holding down the camera remote button until the URC-8811 signals that learning is complete? The results of your learning seem to indicate that you are not. Also, what happens to the camera if you hold down the camera remote button?

If possible, could you try re-learning the button, using the following procedure:

1) Put the URC-8811 in learning mode.
2) Press a button on the URC-8811, the rapid flashing starts.
3) Wait a second.
4) Start pressing the camera remote button and hold it. The rapid flashing will stop, but KEEP HOLDING the camera remote button down.
5) Eventually the URC-8811 will flash twice indicating that learning is complete.
6) Pick another button and repeat steps 2 thru 5.
7) Press and hold the URC-8811's 'SET' button, wait for 2 flashes, this ends the learning process.

In the meantime, I went ahead and created an upgrade anyway.

Upgrade Code 0 = 1F D0 (VCR/2000)
FF 00 11 80
End

Upgrade Protocol 0 = 01 FF (S3C8+)
40 98 01 8B 0E 84 01 00 02 01 65 0A 55 01 20 3F
44 BF 68 8D 01 46
End

Here are links to the various files:

IR: canon_digital_rebel_IR.txt
PB: Canon_Digital_Rebel_Camera_PB.txt

Wow, now that I see how you did it I'm not quite so helpless anymore. I'll waste a little time from here and will post the finished product.

Thank you for your help!

[The Robman]

If you get a chance, please give the upgrade a quick try and post back here to say whether it works or not.

I found the Pronto CCF is posted at DPReview.com for Canon remote control RC-1 (that can be used with Rebel 300D and other Canon cameras)

http://forums.dpreview.com/forums/read. ... ge=7701655

and can be downloaded from
http://www.malaquias.net/PublicPhoto/EOS300D.zip

According to that IR Code for instant snapshot is
"0000 007d 0001 0001 000f 00f2 000f 0cdb" and

2 sec delayed trigger is
"0000 007f 0001 0001 000f 00b0 000f 0cbe"

Rob,

Great work! It works perfectly. I'll work up a delay and program a file that gives a delay based on which number key is pressed.

Thanks for your help.

Here's a ccf for Canon Elph that uses the RC-5 remote, I believe:

freq=32.9KHz

Did you have any luck with this? I'm back from vacation now and might get a chance to do this sometime over the next week. It's pretty easy to do.

Just to be sure, what you're looking for is, when you press the '3' button (for example) the remote does nothing for 3 seconds, then fires off the signal, is that right?

[tradcli]

yep, thats the idea. But i have a refinement of the protocol to work on first. I have worked out two signals that I need to deal with.

The first is similar to the one you worked with and what it does is focuses the camera, delays two seconds, and then trips the shutter. The second simply immediately trips the shutter no matter what the focus is set at.

I see value in having both. How do you program multiple signals into one protocol?

this is the one that you already did
36363 khz
+714 -5330 +576 -130494

This one works the same as the one you worked up but is translated from the pronto files posted above:
32520 khz
+456 -5416 +490 -130580

and this one is the instant shutter trip:
32921 khz
+452 -7326 +486 -130584

I took the latter two and built a separate protocol for each just like the one that you did using protocol builder. They both work independantly.

I also downloaded the delay routine that is posted in the file section but can not readily see how that one works (not from a usage standpoint but from a programing standpoint. I take it it is just a s3c8 machine language loop of some kind? Plugged into protocol builder it does not seem to decode. If all three could be combined it would simplify the whole thing. Of course I could just upgrade all three separately and go from there, but that is not much of a challenge.

Years ago I did a little motorola based assembly language programing, but that was a long time ago. I thought about trying to disassemble it but I don't have the tools and things have changed alot!

I'll upload both protocol builder files to the file section.


Thanks,

Tradcli

Are you saying that you need a different signal to focus the camera than what you need to trip the shutter? If so, how do you do this when you are using the camera's own remote?

Apart from the fact that there's a 4khz difference between the one I made and the other two, I'd say that from a useage standpoint they are all similar enough to probably be the same signal.

i have been working on a version with delay built in but haven't quite got it working yet, here's my work in progress

[tradcli]

Rob,

The way it works is the one signal causes the camera to auto focus, waits about 2 seconds and then the shutter trips. The other simply trips the shutter. For normal operation the focus-delay-shutter is fine, but in some situations it doesn't work well. The use of the instant shutter trip one over the other is that if the camera (sitting on a tripod) is pre-focused to provide a particular effect, the second signal doesn't change that manual preset. Uses may be a particular portrait composition where one wants the area of primary focus to be softer than normal or in a situation where the primary focus point is not the subject.

The command that causes the auto focus with the delay would change the focus setting and cause other than the desired result in that particular situation. Other uses include situations where the focus is set for infinity and refocusing causes issues with the timing of the shot or will result in focus error because of lack of light (wildlife shots, moon shots, time exposures, etc.).

This Rebel digital camera is really quite an amazing device.
