Added "IR Prox Release". Wave two times in front of IR sensor to take a picture.

There are three versions now on the table:

* Sergei's latest version (at https://chdk.setepontos.com/d/3290/691), with "IR Remote Release delay" and "IR proximity release".

* Vatoz's latest version (at https://chdk.setepontos.com/d/3290/646) with "IR Remote Release delay" and "SetM1 and SetM2" [see also https://chdk.setepontos.com/d/3290/649].

* My own version at SVN, based on "2011-01-30_IR" from Sergei, but still not released as it does not contain any user-visible changes.

I have been studying the code, and have gained some knowledge and confidence; I plan BIG changes to the core of this hack real soon (stay tunned!), and keeping in-sync with my changes will probably be hard for other developers. I will try to add all new features released here to my version as soon as possible, but of course everybody is invited to collaborate (the repository is still open to anybody). Meanwhile, maintaining separate branches probably is the wisest idea.

Thanks Sergei: can you explain us better what exactly does your new version? I didn't understand very well.
Thanks again.

Once you press menu button, then display and then use the direction buttons to get to and turn IR Prox Release to the ON setting, when ever you activate the IR sensor under the Viewfinder eyepiece, that turns off the LCD screen, quickly twice in a row it will take a picture.
This way you have remote shutter release with out any additional hardware and a nice sharp picture due to the lack of vibration from a physical button press.
I should also note that the mode dial needs to be in a position that is indicated by letters not a picture to get to the menu that turns it on.
It can be left on because its not often something will activate it by accident.

It works EXCELLENT! and many thanks to Sergei for adding it.

Noooo, fantastic!

Riccardo78

Tnx Sergei!! A very useful update!!

Kekk_400D

Fantastic, sometime it doesn't run but it's very useful!

So... what is the point? How is this different from using the shutter delay (activate the MLU for a 2s delay)?
[A real question, not trying to troll]

No touching the camera. Also, you're not stuck turning the delay on and off.

I'm trying it out today. Didn't know sergei would code it that fast!

So what are you planning to do to the core? Optimization?

Still not convinced... a remote release is just a couple of bucks; but if people likes this so much, I guess it must be useful to you.

Yes, that was quite fast.

Would not want to over-commit, but I am planning a full rewrite.

code rewrite would be great! the code is not in very good condition ATM. That would make it easier for new devs to start.

I have just released my 2011.02.11-0 version:

* Josean0: deactivate UP / DOWN buttons when camera is at the face, to avoid changing ISO / WB with your nose.
* eduperez: better detection of double-event buttons, and some code clean-up.
* I tried to merge Sergei's "IR Prox Release", but could not make it work; will try again later.

Available at http://code.google.com/p/400plus/downloads/list; enjoy it.

Could a few extra shutter speeds be added around 1/30 sec so we can fine tune the look of moving objects?
When I want to get a pic that shows movement, I go to 1/30 sec, but most of the time I need to adjust the speed up and down a little to enhance or decrease the effect to get it just right.

Hi eduperez! I don't know if you knew, that code was for auto-repeat key action while key held pressed.
Example: You need to increase AV compensation from 0 to 6. Just press and hold right button until av comp gets to 6.

			switch (pMessage[1])
			{	case BUTTON_UP:
				case BUTTON_DOWN:
					for (t=0;t<5; t++){ SleepTask(100); if (!double_key) break;}
					if (double_key) goto repeat;break;
				case BUTTON_RIGHT:
				case BUTTON_LEFT:
					switch(option_number)
					{	case 1:
						case 2:
						case 3:
						case 7:
							for (;t<2; t++){ SleepTask(150); if (!double_key) break;}
							if (double_key)SleepTask(150);
							if (double_key) goto repeat;
					}
			}

Why stop there. If we truly can't go higher than the max shutter we already have, a more consistent shutter setting would be nice.

From 1/30 it goes right to 1/45 with no steps in between. After 1/90 it jumps even more. Can we add a selectable shutter increment? Like +50 +100 +5, etc? Is it mechanically possible? Having the option to go back to "classic" shutter increments would be nice too.

Before I can implement the changes I have in mind, I need to simplify a good part of the code, and some non-critical features will be temporarily deactivated; when the new version settles down, I will bring them back.

Next on the list is the extended autofocus pattern selection... does anybody really use all those weird patterns?

Ciccio

I personally never use extra patterns. I only use either single central point or the remaining points all together.

Thank you so much for your INCREDIBLE work. Your show the canon people how the work should be done!
This is a firmware what should be integrated from the beginning inside the body. I use mainly the 5dmII &7d, d3x.
But after the tweak to my old 400d I start to use it again. Is slow but is so much fun to play with it.
Thank you so much for this work and keep it going! With huge respect all the best, Tom

nxb

I use them sometimes. Don't ax all the features.

eduperez

Does anybody here know where can I find a decrypted firmware dump? There is lots of information missing from the current source code, and even just looking for relevant strings could be very helpful. Thanks.
