you are using DMY scheme to name files. that is not very good for file sorting.
can you use YMD? 😀
Y - year, M - month, D - day
I'm not owner of DSLR.
Just watching your progress 😀
Good Job!!!

I´m just missing ISO lower than 80 😉

T.B.

No Answer is a good answer:

The newest .bin is the best. No problems!

Hi again,

Too busy preparing company half year financial report, so have not much time for this .bin project.

Here a copy that can set iso 16, 32, 40, 50. Bin: http://depositfiles.com/files/rppxv8lkt
But it has some limit:
- Can not display iso vavule of 16, 32, 40, 50.
- Pictures seem to be overexposed at these low iso (infact ISO80 overexposed 1/3 av)

Bye!

Hi,

can disp iso 16, 32, 40, 50 on screen now, will upload soon after test ok.

really get stuck, can't find a way to show spot mesure image on screen and don't know how to create a custom menu too.

thaibv

Hi again,

Here are .bin and source code files that can display iso 16, 32, 40,50 on screen (have to use a difference way to show these low iso values, so it blink/flash screen).
bin: http://depositfiles.com/files/oe1vx3kai
code: http://depositfiles.com/en/rmv/2154911844222577

New features:
set: Shoot without card ON to access low iso speeds
set: Beep ON to enable auto AV compensation for low iso speeds

Objective task: Spot mesure's image on screen

T.B.

Working.
But the "beep"..... i hate the beep.... 😉
Isn't it able to put more/these functions into the CFn.?

What do you mean with: "Objective task: Spot mesure's image on screen"? Your next "project"?
What about the ISO3200 in the menu?

And BIG thanks for your great work! I really like it 😀

Hi thaibv,

your new .bin File works great.
I just installed it on my 400D.

Only one thing... I disabled the beep tone in the menu but there is still a beep while changing the aperture value (scrolling the wheel). This is very annoying i think.

Do you know why the photos are overexposed on ISO lower than 100? Is it because ISO 100 is the minimum sensitivity of our sensor?

Thanks for your great work! My EOS is hacked now... how cool is that!
I hope we hear more of you soon.

Hi,

@T.B. and Lefty:
- I foget to remark a test code, so it beep when scroll the wheel (will correct soon). This test it to enable AvComp setting to +4 or -4 stop (default is 2)
- If you don't like the beep, I will eliminate all beep sound folow your setting of Beep in main menu. But this way, could you advice me a default Canon's function that I can use to signal my code when to turn on/of the auto change AvComp.

@ T.B.: I concentrate on showing Spot image on display now, becoz Canon have no hidden Iso 3200 option to unhide (sure). The only way to show it is to make a custom dialog with full range ISO selection (hide default ISO dialog). But I still have difficulty on how to create a dialog. Too much work :'(

FYI: found out a method to display low ISO value that don't flash/blink screen. Keep checking new post.

Lefty

Hi,

its not easy to find a suitable function for AvComp.
I think the best is to take a totally needless function, maybe Menu3 -> Print order-> Set up -> Date on/off or FileNo. on/off.
I never use the print functions on my EOS (maybe others do?).

But... why not enable AvComp by default when low ISO is enabled?

regards,
Lefty

Hi,
I've just uploaded new files here
Bin: http://depositfiles.com/files/7kp2livfw
Code: http://depositfiles.com/files/g83nmqofy

Set Video System to NTSC/PAL to turn Auto AvComp on/off respectively. No anoying beep sound 😁

T.B.

Great! No annoying beep sound.

BTW: You could use every function in print-menu. Noone needs this menu.... 😉

thaibv

Hello,

Finaly it is completed. Here are my lastest .bin and code files for 400d.
bin: http://depositfiles.com/files/hb6wg7y00
code: http://depositfiles.com/files/tn7h7n13n

Now you have Spot meter, full ISO range from 16 to 3200, auto Av compensation for low ISO (16 to 80) and especially it can display ISO value, Spot meter logo on screen.

Although it slow your 400d a little and you could not take a pic at 0.2 sec after turn on as original. However what you gain are much better.

One thing I worry about is my 400d's card door and card socket 😁(open/close, insert/remove a thousand times for test).

Lefty

Good work!
The new release works fine. 😁

T.B.

Yes. Great work. Spot meter logo is working fine (a little bit small, but okay!)!

Very good! 😀

jogreher

Good work!
The new release works fine.

hey thaibv you should consider checking in your code in a public subversion repository, like we did with chdk. doesnt cost anything but its very useful. and it's not even difficult, even a child can do it. but it has a lot of advantages.
great stuff ur doing by the way. one day i will try it on my roommates 400d.

whoever

It would also be nice to edit the dedicated wiki page, to reflect the state-of-the-art.

edit: And then, perhaps, to change the color of the corresponding link on the For Developers page.

hi and thanks

I believe that the last release has a bug with iso setting

you will see no differences between Iso 1600 and 3200 as well as iso 16 - 100 (i.e. sensibility of sensor in Iso 1600 is the same as iso 3200 if you shoot with the same time and ap.)

but the spotmetering is fantastic !

In release of post #120 the iso works fine

thanks

T.B.

Full ack.
Sometimes it seems to work. The actual release is a little bit buggy
