After i save a preset at 3200 (called it nitemoves lol) when i return to main screen is says 1600 til i hit some other button then it changes by its self back to 3200.

When finished naming a preset and you come back to the preset list if the preset you just named was the one highlighted it would be quicker to save the preset there .

JoeNeptune

If you could activate the auto play it could be used as a screensaver.
If pressing of the display button could be simulated it might be a bit more interesting alternating between the histogram and the full screen picture.

Man, you have to stop yourself !!
Please !
Be Real !!!
Stop that bullsh*t !
That is way too much already !
I do not want to be rude, but
I have got too much of you !

If you want to suggest real things, please start with reading the code or at least the commit logs and the issue list, so you will have idea what is real and what is nonsense !

Until now you're only flooding us in the forum and in the issue list.
Please read more, talk less !
Test more, report and suggest real things !

This is f*cking annoying...
Please read all your posts (for the last 2 months atleast), please !

JoeNeptune

I have read just about every thing.
When you say comment log and issue list do you mean the same thing?
I ask just in case there is a different comment log to read other than the comments on the issues .

Just to name a few of my recent contributions.
2 bugs reported on this page
2 bugs reported on page just before this one.

Not to mention the invention of 1 feature -hand waving

I don't want to argue, I just want you to think before you post !
when i said commIt log (i.e. not commENt log) i meant this: http://code.google.com/p/400plus/source/list

JoeNeptune

Thanks for pointing me to the changes discussion.
And the programing word of the day "commit".
I hope you can spend that all energy next time telling me exactly what i am saying that is being misunderstood or might be based on a misunderstanding.

So, I have been reading some from those particular pages you mentioned.
On the page http://code.google.com/p/400plus/source/browse/trunk/funclist.S?spec=svn463&r=463
Where it says :
1659 DEF(StartMnAutoPlayApp, 0xFF86FC2C)
Is that defining a function that can be used by us?
If it is something else then what?
If we cant use it then why?
I have been asking about the funclist for a while but no one has said any thing about it.
Other wise please explain how are functions found?

I totally agree with 0xAF. Joe, please stop posting your unqualified ideas and try to stay realistic and constructive...

0xAF

Sorry for being aggressive, I just had a blackout...
so about the funclist.S
this file is a dump from what routines are found in the firmware...
just the names, we do not know what arguments they have and what they do...
to tell you what StartMnAutoPlayApp() exactly do and how to use it... we'll have to spend some hours in reversing the routine... most of the routines we reverse are just a small part of a big puzzle...
after we understand what this routine() do, we will find out some of the other routines connected to the puzzle, then we have to spend many more hours until we finally find what is this function of the camera ... and start to use it...

in that matter ... you'll see alot of names in funclist.S, but very few of them we know how to use...

Hi,
first of all thanks and thanks again for your job, I'm appeciating very much. I'd like to ask a simple thing that I cannot understand: is it possible to assign a name to a preset? If yes, how? Thanks in advance for your suppport.
Ciao
Francesco

JoeNeptune

to rename hit the buttons in this order; menu, DP, DP, menu, set . making sure to highlight the preset you want to change before pressing the second menu button .
while editing it the menu button deletes the rest of the line
pressing set while on the name will enter it and exit.

assuming your version works like the one I am using currently, the nightly build that was available yesterday.

correction: I cant seem to find the delete and capitals while editing in this version. It was there in a version before.
But you can still type over mistakes

The ability to rename presets is still work in progress; you can download and try one of the nightly builds, but there is no guarantee that it will work, or you can wait for the next release.

When using hand waving with no delay, one shot, repeat, instant with a 30 second exposure and only when there is a lot of dark frame subtraction afterwards as is indicated by the busy icon and the red light going on for several seconds afterwards it will take a second picture with out a second hand wave instead of displaying the picture when it is done. Then one has to wait about another minute for the second exposure and dark frame subtraction.

Also I would like to add the personal observation that when working in the dark, with the screen off while it is taking a picture, the flashing blue light is a bit distracting and slightly blinding. But if that is just a personal problem i can easily just put a little bit of black tape over it while in that situation.

I must say that I really am impressed that you can turn the hand waving on, work with both hands free on the camera and then take a picture without having to go and grab something else. This makes things much easier in the dark.

I would like to learn more details about hooking firmware functions.
I am not sure I would be good at learning a new programing syntax after a 30 years with just knowing one.
But hooking functions sounds like fun, please pardon the pun, and how many parameters could simple functions like auto play have?
Any tips on this?
Any pointers to more reading material on this subject would be great.

start here and if you are interested after that, i'll PM you the next step.
http://www.idabook.com/
(the url is just to point you to the right direction, you will find more materials on the net)
you will need some ASM knowledge too...

JoeNeptune

Is this the process I would need to use?
Or is there a better way?

http://magiclantern.wikia.com/wiki/IDAPython/Backtracing

0xAF

I haven't used that... the file you'll need is already available here in the thread.

JoeNeptune

Would you please tell me its name, about what page and/or a keyword I could use to find the file.

JoeNeptune

Thanks

Now does anybody know how to get the tracer window open in IDA 5.2 ( i thought i take a look with this version first)

and Is the graphical flow chart only available in IDA Pro 5.5 or am i missing something or is it just not available with what we are doing?

0xAF

To trace the code, one will need somewhere to run the code in first place.
And AFAIK you cannot trace the code, as you cannot run it on your PC (unless your PC is the camera itself), neither you have JTAG (or any other debugger) connected to the camera while the code is running there.

Now about IDA:
Please do not post questions related to IDA on this thread, as I said, you can find any information on the net. Google is your friend.
Do not expect someone here to teach you how to use that product, or how to reverse some code with it.
I hope you are using a free version of IDA (http://www.hex-rays.com/idapro/idadownfreeware.htm) or perhaps you brought a license for the version you have. Stop asking for troubles here.

JoeNeptune

Don't worry, it happens to be on a friends computer.
There are computers with licenses.
I didn't think asking about it would be a problem because when I search the term in here and get 9 pages full of just messages containing the name of it.
But OK, I agree, I won't beat a dead horse concerning this.
And thanks for the tip.

@JoeNeptune:

I'd like to help you with the disassembly, but I must confess I have never done it myself; up to know, all my code is based on call to functions that others have found and documented.
