550D & 500D porting 14bit RAW DNG silent pics

[wolf]

I'd like to ask if someone could help porting DNG pics to 550D.

I've posted a porting guide for DNG silent pics here:

http://www.magiclantern.fm/forum/index.php?topic=5240.msg32128#msg32128

Like a1ex said I took a screenshot of "Show EDMAC" before and after I pressed "Don't click me!"
before: after:

1. fill in the "blanks" in raw.c
#if defined(CONFIG_550D)
#define RAW_LV_EDMAC ? ? ? ? ?
#endif

What is the right address?

[a1ex]

EDMAC #16 (1888x1181) seems to be the one. That is c0f26008.

[Greg]

That is c0f26008.

Works on 500D 

[wolf]

Thanks a1ex.

2.

Code: [Select]

/**
 * Photo-mode raw buffer address
 * On old cameras, it can be intercepted from SDSf3 state object, right after sdsMem1toRAWcompress.
 * On new cameras, use the SSS state, sssCompleteMem1ToRaw.
 *
 * See state-object.c for intercepting code,
 * and http://a1ex.bitbucket.io/ML/states/ for state diagrams.
 */

#if defined(CONFIG_5D2) || defined(CONFIG_EOSM) || defined(CONFIG_650D) //FIXME: 650D is untested
#define RAW_PHOTO_EDMAC 0xc0f04A08
#endif
I mirrored http://a1ex.bitbucket.io/ML/states/ and tried to grep c0f and C0F without result to find the site with the value.

@Greg
What did you use for

Code: [Select]

#define RAW_PHOTO_EDMACDo we need it anyway?

[Greg]

I use the values 5D II

Code: [Select]

#ifdef CONFIG_5D2
#define RAW_PHOTO_EDMAC 0xc0f04A08
#endif

#ifdef CONFIG_500D
#define RAW_PHOTO_EDMAC 0xc0f04A08
#endif

#endif


#ifdef CONFIG_500D
    //~ { "Canon EOS 500D", 0, 0x3479,
    //~ { 4763,712,-646,-6821,14399,2640,-1921,3276,6561 } },

#endif


#ifdef CONFIG_500D
skip_top    = 24;
skip_left   = 74;
#endif

Yeah.. :-) Thanks for helping.

Yeah.. :-) Thanks for helping.

Hey Wolf! Care to share your bin so I can test this feature?

[wolf]

Sure

[mk11174]

Sure
http://www.file-upload.net/download-7600974/autoexec.bin.html

Awesome, Thanks!

[ashtrai]

Whats the easiest way to try this out on a 550D? Replace the autoexec_bin file on my card is a given, but what other files (modules etc) do I need?

Try these values ​​for the 550D:
1095, 1092, 1059, 1008, 917, 844, 744, 645

[wolf]

I took them from
http://www.dxomark.com/index.php/Cameras/Camera-Sensor-Database/Canon/EOS-550D-pre-production
but it's the (pre-production model)

the commercial model is not available.

I'll try your values.
Thanks

Great Wolf ! Many thanks ! You are great ! 

Do your mods are (or will be) integrated into the official unified builds ? Let me know ! Many thanks !

[tihon]

Can you upload any tetst? Please

[Greg]

500D raw silent pic + intervalometer :

[dlrpgmsvc]

Full resolution frame example on 550D (1736 x 1156 pixels) (1 second fixed exposure, independent of the exposure time you set) -> https://dl.dropboxusercontent.com/u/46130896/sample.jpg

Max speed is about a frame every 2 seconds on 550D with a 30 MB/s 8Gb Sandisk SD card

To take silent dng, go to camera settings on ML menu and enable silent pics (ON), then put the rotating knob of the camera into M (manual), then push the liveview button (the red one) then keep half pressed the shoot button to start silent-shooting. Release it to stop the sequence.

[dlrpgmsvc]

Some questions :

[1] Do the capture resolution can be selected ?
[2] Do the exposure time can be selected ?
[3] Do there is hope to run a little realtime movie (at least at 24fps) by tweaking something (resolution or exposure for example, or other things) ?

Many thanks !

[tihon]

It would be nice to have 1280x400 as 600d RAW DNG with 24 fps. It should be posible

Not bad for timelapsers)))

How do I find these values?

Yes ! It would be great ! Let's pass the ball to Wolf...   

[Greg]

500D :


500D max image buffer is 2000 x 999?
This is RAW_PHOTO_EDMAC

[a1ex]

On 5D2, that edmac is reused for something else (and that's the reason for capturing it from the state objects).

[ecek2]

with zoom, picture size is 2368x1080 4.68MB. but almost everything green

[a1ex]

Skip offsets need to be adjusted then (they are too big).
