How did you compile QEMU version 2.3.0?
I've got 1.6.0.

Did you have any scripts? There is no menu for lua itself, scripts can create or add their own menu items wherever they see fit. You can check the console for script loading/status/errors.

Yes.
/qemu/sdcard/ML/SCRIPTS/{CALC.LUA,EDITOR.LUA,SOKOBAN.LUA}
It seems to me that QEMU doesn't "look" for the script folder.
I did run your lua module on my camera and it did work very well.

$grep SCRIPTS log.txt
[FIO wrapper] readdir() => SCRIPTS size=4096 mode=10 time=556420ee

@dmilligan
I tried to load the lua module, but nothing did appear in the menu.
Anyway, the QEMU progress is impressive.

@themichael
you need to fetch the lua-repository.

Delete your ML folder on codio.com.
cd to workspace.
hg clone -r lua https://bitbucket.org/hudson/magic-lantern

Cool.
I remember the PicoC API which was perfect for me.

I think power saving options i.e. display off/on are very useful.
Also key events, key press emulation and a text output like
"void bmp_printf(int fnt, int x, int y, char* fmt, ...); "

Thanks for bringing back a script module.

I compiled it with your "Compiling Magic Lantern in the Cloud" tutorial. Works great btw.
How do I start a script or is it too soon to test? (550D)


My test script:

Code Select Expand

print("hello, world");

You could try the the nightly builds. The silent mode produces  raw images.
ML became a rolling release model, the latest stable version is kind of obselete.

i bet when you get a gun pointed right onto your head, you will give out the key.
well, this is a drastic example. but there are coutries where you have to be afraid of some kind of punishment.

And what if is known that ML can hide images...

I don't think so. In fact I believe that the use of crypto does not imply wrongdoing at all.

Same here.
So why hiding the crypted files then?

Using Ruberhose as a group would make every card in a Canon and every user suspicious of holding some secret photos.

- PicoC as a module (very easy, should work pretty much out of the box, moderate C knowledge needed, but is it worth it?)

I think yes.
One thing or disadvantage is, the speed of PicoC. That's most of the time not that important and it isn't too slow to write games like a1ex did.
The other thing is that it's far beyond my skills making a module with a scripting language.

Looks like kind of complete.
There is also a manual to be sure. ;-)

Ml became a rolling release model.
The latest nightly version is considered as stable.

How do you know that it was a Canon?

You can run ML without touching Canon's firmware. All you need is to set the boot flag of your SD-Card and copy the  ML files to the card.
Be aware if you insert a card with the boot flag set but without the ML files the camera won't start.

If there were ghosts to hunt, watch or film, ML would have such a feature I guess. ;-)

You could trigger your camera externally with ptpcam.   

@dmilligan

Looks great.
Is there a picture of your dolly that you build yourself. 

Do you have silent pics checked?

Then the display turns off after 15min whithout pressing the display button.
What I meant was to have two or as many as presets different powersave settings stored along with the display settings.
Maybe others find it usefull too.

Be sure that you trigger with the pause after the Canon stuff disappears. Canon display settings are set to most less information. (I don't know the 600D).
You could try to set a longer pause.
Silent pic was set to "Simple" while trying.

sure.

Code Select Expand


[static unsigned int silent_pic_polling_cbr(unsigned int ctx)
{
    static int silent_pic_countdown;
    if (!display_idle())
    {
        silent_pic_countdown = 10;
    }
    else if (!get_halfshutter_pressed())
    {
        if (silent_pic_countdown) silent_pic_countdown--;
    }

    if (lv && silent_pic_enabled && get_halfshutter_pressed())
    {
        if (silent_pic_countdown) // half-shutter was pressed while in playback mode, for example
            return 0;


                     msleep(500);   //added this line



        silent_pic_take(1);
    }
    return 0;
}


edit: I triggerd in movie mode with a wired remote with 50ms signal length.

Maybe it solves the 600D problem too.

I think I found a solution for the silent pink frame problem.
When pressing HS a Canon bottom panel appears which I think disturbs the sp fetching.
As a workaround I set a 500ms delay in silent.c to give the Canon bottom panel time to disappear before taking the picture.

400 frames in a row and more 100 frames rows tested so far without one pink frame on a 550D.

Maybe my explanation is wrong but it seems to work and I hope it will work in the future too. ;-)

I meant when you set your "display off" to 5 sec. to save power and want to adjust the camera while waiting for the right moment you need to go inside the  "Power save menu" to turn it off. Or is there a quicker way to disable Power save in LV.
