« on: December 17, 2012, 10:35:07 PM »

what i can see using Spy prop and adding them to property.h like:

Code: [Select]
#define PROP_STROBO_FIRING    0x80040013  // 0 = enable, 1 = disable, 2 = auto?

Great, I dreamed about it, the 500D does not work debugmsg, so I can not carry out research.
 ;) ;D

I've added options found using ETTL-II as flash mode.
there are also Manual and Multi flash left.

We can overwrite the data? I think the ISO menu, you can add a few features ;)

I hope so, not sure right now.
I don't know how to properly add the value in property.h will try once finished posting them here.
For example "Master flash" and "Firing Group" are related.
If FG is set to all and MF is off we have 0 with MF on we have 1
if FG is set to A:B and MF if off we have 2 with MF on we have 3
if FG is set to A:B:C and MF if off we have 4 with MF on we have 5

I've added here all i can figure out for now, I hope it's clear.
How to put those value in property.h?

for example this is wrong i suppose:
#define STROBE_1ST_CURTAIN 0x8
#define STROBE_2ND_CURTAIN 0xA
#define STROBE_HI_SPEED 0xD

How to specify that it need to go in the 16th "place" (last char of second group) in that prop?
something like this, maybe?:
#define STROBE_1ST_CURTAIN 0x00000000 0x00000008
or:
#define STROBE_1ST_CURTAIN[16] 0x8

You can probably use a bitmask of some sort

In property.h there are those commented lines:
//strobo_setting[0] & 0xFF000000 = strobo_aecomp << 24
//strobo_setting[1] & 2 = 2 if strobo_curtain else 0
//strobo_setting[1] & 8 = 8 if e-ttl meter = average else 0
that are corresponding to my results. Is good this? i can go on filling it, but not sure if it's useful or not.
from what i get, [ 0 ] is the first block [5] the last. Position inside the block is done with zeros

Scrax, you can try to do the same for the internal flash.

The 40D has these properties:

Code: [Select]
PROP_BUILTIN_STROBO_SETTING

PROP_STROBO_CFN
PROP_STROBO_SETTING
PROP_STROBO_WIRELESS_SETTING

Is this correct so:
//strobo_setting[0] & 0x0000F000 = 1 if strobo_manualflash else 0
//strobo_setting[0] & 0x0000F000 = 2 if strobo_multilflash else 0

I've added here all i can figure out for now, I hope it's clear.
How to put those value in property.h?

for example this is wrong i suppose:
#define STROBE_1ST_CURTAIN 0x8
#define STROBE_2ND_CURTAIN 0xA
#define STROBE_HI_SPEED 0xD

(very good research btw!)

i think thats *nothing* for property.h.

create a strobo.c/.h and put these defines there along with the code to access them.
as this is very specific, i recommend adding parameter description too.
e.g.

/** call this function to set the strobe firing to 1st/2nd curtain ...
  *  @param strobe_type: one of STROBE_1ST_CURTAIN  STROBE_2ND_CURTAIN STROBE_HI_SPEED 0xD
  */
void strobo_set_curtain(uint32_t strobo_type)
{
...
}

How to specify that it need to go in the 16th "place" (last char of second group) in that prop?
something like this, maybe?:
#define STROBE_1ST_CURTAIN 0x00000000 0x00000008
or:
#define STROBE_1ST_CURTAIN[16] 0x8

i would add a define to strobo.h
#define STROBO_<propertyname>_CURTAIN_POS (16)
and in strobo.c:

...
property_buffer[STROBO_<propertyname>_CURTAIN_POS] = strobo_type;
...

So this status can be z in my table? Manual mode 3 aother 1 ?
and also the POS in strobo.h are reversed.

so:
#define STROBO_ZOOM_POS (1E) // or 31?

If it were possible one day, we could control the external flashes with integrated flash. The new models already allow this.

Can we use very high speed flash synchronization with ML software?

1. Be able to take images with flash speed sync at 1/800 or higher,
2. DSLR Camera mechanical shutters cant do it. 
3. Can we use ML + Camera on B + ML software shutter speeds

if yes, than definitely this is a whole new world of creativity....

Added also the internal flash prop found, now 9 numbers are unknown or never changed on my camera.
If what i've posted for strobo.c is correct i'll go on filling it.

i personally prefer 0x1E, but both is ok.

Good I'm going on with strobo.c but i'm still not sure about one thing
this 0x80030038 has a length of 0x22 = 34 char
but spy prop shows me: 8+8+7+6+6+6 = 41 char
how can my positions be correct?

strobo_settings must be an array of size 34 iirc and in prop handler you must memcpy the data into your strobo_settings

Googled for memcpy now and come up with this but it's wrong i think  :( :
Code: [Select]

#include "dryos.h"
#include "strobo.h"

size_t n = 2;
uint32_t strobo_settings[PROP_STROBO_SETTINGS_LEN];
PROP_HANDLER(PROP_STROBO_SETTINGS)
{
    memcpy(buf[STROBO_SETTING_POS], &strobo_settings, n);
}

/** call this function when changing to/from manual flash mode...**/
void strobo_set_status(uint32_t strobo_status)
{
#define STROBO_SETTING_POS (STROBO_SETTINGS_STATUS_POS)
    strobo_settings[STROBO_SETTING_POS] = strobo_status;
    prop_request_change(PROP_STROBO_SETTINGS, &strobo_settings, PROP_STROBO_SETTINGS_LEN);

The length is camera-specific; you can define a maximum length and allocate the array statically, but use the length reported by the prop handler when you call prop_request_change.

I've bricked Marvin's 5D3 with a wrong length value in a prop_request_change call. It was easy to unbrick, only took one hour or so.

Wow! I'm working on this too (I want to display the remote flash settings on the info screen), but you were quicker! Congrats!
I'll download your strobo.c and see it.
I want some more readable than a big array, like make a struct for flash settings like lens_info.

But if it is camera dependent we should put it to the platform specific folder instead of src, shouldn't we?

Thank's, I'm stuck now on that, so go on with what you think could be done to make those settings usable.  :)
I suppose like other prop that address is the same and just values are camera specific (for example for wireless flash.)

There are a lot of problem (at least on 7D).
This property only contains data when you are in the Canon flash menu. After that its deleted.
Also when you are in the Canon flash menu, you can see the same data at memory address 7B1A8 and several other places, but when you close the menu then all of them deleted too. I found the property data with memdump in other locations after the menu closed but these adresses changed every time.


Anyway, I fixed all the typos and stuff in the strobo.c/.h so you can compile them and also made a struct to the array.
I can send it to you if you can use it on 600D.

Code: [Select]
struct flash_info {
   int firing; // 0: enable firing, 1: disable_firing
   int ettl2_meter; // 0: evaluative, 1: average
   int expo_comp;
   int zoom;
   int mode; //E-TTL II, Manual, Multi
   int wireless_func;  // Disable, Ext, Ext (A,B,C), Ext+Int, Ext(A,B,C)+Int
   int wireless_channel; // (1,2,3,4)
   int shutter_sync; // 1st curt., 2nd curt, High Speed
   int multi_freq; // (199 = 0xc7, 1 = 0x1)
   int multi_count; //(hex like before 1 = 0x1 18 = 0x12)
   int internal_output; // Flash power values from 1/1 to 1/128 1/3stop: (2,5,8,a,d,10,12,15,18,1a,1d,20,22,25,28,2a,2d,30,32,35,38)
   int external_output;
   int group_a_output; // 0x00..0x38: 1/1..1/128
   int group_b_output;
   int group_c_output;
};

Another thing about your first post with this

I really don't understand how do you count these numbers.
For example, you positioned the c: flash mode to the 0x25 and actually it is the 0x01
When you see the prop spy data you see this:
80030038 0022: "first longword" "second long word" ... "sixth longword"

Doesn't matter if you see only one zero it is a longword (four bytes) so the byte order is:
03 02 01 00  07 06 05 04  0b 0a 09 08  0f 0e 0d 0c ...
EOS 7D Mark II, EOS 7D, EOS 5, EOS 100 + lenses (10mm to 300mm), 600EX, 550EX, YN600EX x 3

Thank's Pelican, now understood a little more why the numbers were not correct. Added to you writing permission on the fork so you can pull your corrections that i'll use for understanding better my errors, if you prefer posting strobo.c/h somewhere i will add them there for reference since I think that probably also 600D has the same problems you found on 7D.
I'm using ML2.3 for photography with:

This property only contains data when you are in the Canon flash menu. After that its deleted.

I'm trying to implement this feature request (switch from hss to 2nd curtain): http://www.magiclantern.fm/forum/index.php?topic=5040.0

But from what you're saying I understand it's impossible to either read or write this property outside the Canon flash menu, so changing anything about the flash from normal shooting is doomed?

Sorry to crash the party here guys, but I was reading this post with interest, would finding these setting help with implementing a ml dedicated flash menu that is easy to navigate to via a user defined button shortcut ? instead of the long winded approach canon has buried deep within their menus, Canons implementation really breaks my flow while shooting and setting up ratios.

I did a feature request some time ago and a1ex mentioned it wasn't possible as of yet here :

http://www.magiclantern.fm/forum/index.php?topic=3392.msg17775#msg17775

If this now possible could you look at implementing the above request, I'm sure it would be a much loved feature for us that use Flash while shooting,

Thank all :)

I agree - while I can change most settings directly on my "big" Canon flash, some things are better done on the large camera lcd and it's a pita to navigate to say "Group C EC" in the Canon menu structure - and you even cannot link items in the flash menu to the Canon "my menu" :-(

Maybe I'll come around to do it sometime later, but as far as I understand it the flash props aren't completely worked out yet (or they aren't accessible until you're in the Canon flash menu).

Damn, that's bad news - maybe Canon wants to sell their expensive flashes as the only sane options to have a fast access to the flash settings? The fact alone that you cannot pin flash settings to my menu is strange ... or maybe Canon's whole flash code is just not integrated well as the camera tends to loose some settings (like the flash group modes) on battery changes.

But to be absolutely sure: The gist of it is that the whole thing is doomed since the props aren't there unless you're in the Canon menu, and then you don't need ml anymore to change them, correct?

6D:

Code: [Select]
*0x77C2C = arg0
_prop_request_change(0x80040014, 0x77c2c, 0x4, arg3) => ret__prop_request_change_FF19A328

The prop changes between evaluative and average... so does mem location.

0x80030038 or PROP_STROBO_SETTING contains values all the time for me. Am I missing something?


Ok... prop is wiped out after playing in the flash settings. But my flash is off the camera and the dialog said as much. So maybe prop shows up only when strobo connected? I hooked up/powered the flash and its back.
* on 600D... that prop has values too at least at the front where I can see with prop browser.

Any news here, anybody did some more research esp. as far as hss on/off goes?

I'd still like to force-switch hss on with ml instead of having to push a button on the flash ... the latter is a major annoyance with Canon because if you forget it after changing batteries the camera stops at x-sync no matter what and simply overexposes all pictures, I've lost a couple of good shots this way.

I'm subscribing to this string. I'm on the hunt for a solution to the second Curtain Sync for non-canon strobe triggers.

After researching this for days before finding the forum, I'm trending towards finding a hardware solution. There's some trigger or electronic feedback that the my Canon flashes give the body that allows 2nd shutter sync that I'm hoping can be remedied with a dongle, if this software solution you-all are working on isn't feasible.

Hi guys, did you manage to find a workaround to the second curtain sync? This thing is driving me crazy. Got a 6D , have to use it underwater with a non-canon flash and i dont have enough space in the housing for any kind of trigger... Thank you very much
