Unfortunately I could not try that because I am on Windows 7 and there grep does not exist. :-(

I am on Windows XP.
It will horrify developers who love obscure Linux tools but I just use Windows Search.

You have to modify registry settings to make sure files with normally unsupported extensions (such as .S) are searched.

Cannot remember the details, you will need to search for that.

Hi waterwingz and Microfunguy,

thanks again for your help!
I think I will give Cygwin and wingrep a chance ;-)

@waterwingz:

I started to analyse your patch for middle terminal, but have a few questions:

1. The patch you provided on which version of trunk I can apply it to?

2. What tool you use to apply a patch - or do I have to do it manually?

3. You wrote that you have the HP timer stuff in the dev trunk.
I am a littlebit confused now, what is the dev trunk and current trunk for you?

4. Is your batt mid term code currently working with the HP timer or not?
Since I need very short reaction time on sending a pulse to the S110 I think I will need the HP timer as well.

5.

Does this mean the battery mid terminal will trigger taking a picture like the USB port does?
How you set the mid terminal to high / low? Do you have certain resistor values for the two states?

1. The patch you provided on which version of trunk I can apply it to?
As mentioned,  it's for the dev (or unstable 1.3.0 trunk).  But there have been enough changes that it will not apply cleanly anymore.    I can fix that for you if you are interested in trying it as is.   Or if you can wait a few days,  I'll have a more complete version suitable for inclusion in the main 1.3.0 build.

2. What tool you use to apply a patch - or do I have to do it manually?
I just use the "obscure"  patch command.  Cygwin will have a version of it that you can try.  For Windows use,  there is a winmerge program you can google for.  (http://winmerge.org/)

Update :  if you are using TortoiseSVN on your Windows machine (recommended) then this might help : http://tortoisesvn.net/docs/nightly/TortoiseSVN_en/tsvn-dug-patch.html

Dev = unstable = 1.3.0   Current = stable = 1.2.0

Not yet.  Should be no problem - just need the time to get it added.

Yes

My current thinking is to use a #define in platform_camera.h

Here's an updated version of the A/D channel 5 patch (uses A/D 5 rather than USB 5v to trigger a shot). Patch for the current 1.3.0 3419 trunk.  I've added the necessary changes for the S110 (in addition to the G10 and SX200is) for your convenience.

@philmoz :  when you get a moment,  would you please add GetAdChValue to stubs_entry.S for the dev trunk?  TIA.

Update : v5 now attached - works better with ptp

I think I will wait the few days since I can other things to first like creating the software on my microcontroller, study your code and also get familiar with TortoiseSVN. So I can wayt no problem.

Sorry for beeing unprecise, I wanted to know the technical / hardware part.
What circuit / resistor do you use to trigger the battery middle terminal? Do you apply a digital value like e.g.

1000 Ohms equals low
1500 Ohms equals high

Or do you 'send' any analog value to the batteries middle terminal using PWM or similar?

Try using grep -r main.c to get some idea of how the whole CHDK build goes together.

I installed cygwin and tried grep -r main.c but not sure what I can get from the provided information, see attached image.


BTW: how to insert inline images in this forum's threads?

That's up to you - the code won't care.  It just assumes "On" for a resistance below a certain value and "Off" otherwise.   You probably need to read through this thread :  Battery third (temp) terminal as multipurpose analogue input and maybe use circuit "A" from this post : http://chdk.setepontos.com/index.php?topic=10385.msg109169#msg109169

The fourth line shows you where main.c is included in the Makefile.  Once you know that, you should be able to figure out where to insert your testcode.c filename so that it gets included too.

Store them on an image hosting side ( eg imgur.com ) and use the Insert Image button from the edit toolbar to embed the resulting URL.
