What I need to compile from sources the newest version of this extension?

2) Has anybody tried to fix ISO 3200 name to be ISO 4000 as mentioned earlier and set intermediate value to memory location to get ISO 3200?

I posted the code snapnet for it a few pages earlier. But I haven't compile it as I am lazy to install GCC compiler. :p

AEB extended to +- 6.7

This AEB extension not works for me :/
(same effect as 'normal' aeb)

OK, nevermind, You need to press not <MENU> button but <INFO> (works just like iso changing -and about iso changing... before this hack <LEFT> and <RIGHT> arrows was changing iso by 1/3, now it's broken ;(

btw. Have You found function to set RAW+S (JPEG (fine-this "stairs" symbol)) or other configuration (Raw, M-raw+s/m/l jpg?
If it matters - it would be nice to see it under "jump" button

Vbscript

I have combine the old iso 1/3 step and the new aeb one 😀
<up and down> is the iso 1/3 step
<left and right> is the aeb

Hello!

I am very thankfull for all of you, who hacking code and give advices 😀 I want to report, that latest version of code (published in reply #103) has the same error as previous versions. When I turn on my 350D, wait until leds are stop blinking and press INFO first time - arrow immediately do their work properly. After everything is set up I just press half way shutter btn and camera return to shooting mode. Everything works fine. BUT when I press INFO second time (in case I changed my mind and want to change ISO or sth else) - i MUST press any arrow several times (up to 8 ) to ANY change take effect. Can you try to fix it?

Do you know how to enable RAW + Small JPG picture writing mode?

I am also interested is possible to hack info protocol to allow old sigma af lenses to work with 350D. To be precise - these are working properly unless user try to step down aperture from wide open to any value. Err 99 is reported by body. Interesting thing - the same lens is fully functional with newer EOS 40D.

more info about this area are here:
https://chdk.setepontos.com/d/1331

EDIT: one more thing - when I put into body erased, clean CF card, camera do not work properly - I can't take a photo at any mode and only partial info is shown at lcd display. Is this normal signs when boot flag is set to ON and clear CF card is in body, or sth is wrong?

When I shoot overexposured photo and when I turno on it's preview with maximum information and histogram - the overexposured areas are blinking. It's excellent, but is possible to enable this feature in big preview, without histogram? I do not know is this feature present as original or modified one, I can't find it anywhere in classic menu.

Have a good weekend

hi,

im having some trouble getting the bootflag set/running the firmware update.
i dont see a blue led lightning up and nothing seem to happen.
i dont recall ever seeing a blue led during normal operation though. Is it located in the same place as the cf activity light
or at the dp button?

any thoughts on what might be wrong?

Vbscript

Did you update the firmware?
You need to update the firmware first and then do the hacking.

annuges

yes, im on 1.0.3.
i dont know if thats the most recent, but it was mentioned earlier as working.

i tried to just continue along with the instructions just to make sure its not just some dumb problem like the led broken,
but nothing happens (the card is defenitely booteable, i set this via the chdk card program and verified via hex editor).

assuming you alreaddy did this to your cam, where is the blue led located?

thanks in advance

maxes

I try agian , and :
Stopped at read_bootflag(buf1, buf2);
I have 1.0.3 too.
Once again - from which source is address 0x001059b0 ?

> your cam, where is the blue led located?
It's button with lamp icon on it and with print icon below .
In shot mode this button used for light status display.

igorb

I assume you used CardTrick software for making CF-card bootable did you select "CF boot sector" option at the bottom right part of the window (I had the same problem as you until I checked this option in CardTrick)

annuges

igorb: yes, but from what i understand this isnt relevant for the firmware part and only needed later

Anyway, it works now!

i recompiled the firmware without any modifications to the code to test my compiler setup was working.
i used that new firmware in my camera and it worked!!

thanks to anyone working on this,
awesome!

(im on a mac though, so that problem/solution might not work for someone else
also for anyone else not working on a windows system: the decrypt20d application is provided as exe, so you will need to run it in wine on the compiled .bin file to get a valid firmware)

edit: now that it works, a litle wish list for the devs:

would it be possible to make the AEB do more pictures? for example not just -6, 0,+6 but -6,-3, 0,+3,+6

maybe there is a way to set aeb to a value, let the user take the 3 pictures and then automatically set the aeb to half the original value and let the user take another 3 pictures.

so first -6,0,-6 and then -3,0,3

this would lead to a double "0" image but to me this seems to be a quick way to get this running.
im no developer but since its already possible to stop aeb after one usage, shouldnt it be possible to instead of disabling aeb to set it to half its original value and let one start again?

i hope all this makes sense 😉

Hi,
I am thinking of the feature: C. Fn 03 - Flash Sync. Speed in Av mode to set from fixed 1/200 to variable 1/60 ~ 1/200 like the newer DSLR.

Would it be possible to implement that on 350D? Thanks.

Colour Temperature Enabled:

1. Press <INFO>
2. Press <UP> or <DOWN> to select feature you want to change (ISO, AEB or Colour Temperature )
3. Press <LEFT> or <RIGHT> to change the value of the selected feature

Patryk

hmm and what about 1/3 iso jumps that i've seen in last version?

btw. is it possible to add option for bigger jumps, like 500k?

au_courant777

Im just curious. In the custom function there is "superimposed display". I just want to know what is this for and how to use it. Thanks in advance

sergiomega

cyrustam, some way to come back with the 1/3 ISO stops togheter with colour temperature?

I think the combination of spot, colour temp and the 1/3 iso stops makes the camare perfect for me.

Andy386

Thanks for the great work!
A huge list of new features. wow!
maybe anyone can write all new stuff down in one post?

Would it be possible, to stream videosignal (wich is transmitted via USB if camera is connected to a PC) directly on CF?
Or make a better zoom-tool in past-view? or even liveview+zoom (usefull for noobs to focus with manual lenses)?

Can my 350D make coffee ? Guys, firmware mods are cool, but they can't make a cow morphing into a horse

Set 1,2,3 😀
Good job!
