Thanks, thanks, thanks,... forever.

I have just installed Sergei 2011 -1- 27 build of the autoexec.bin - All things run perfectly.

One question though to Sergei does the latest build include all the features of the previous builds or is it a different flavour. Does this build have autoiso ?

Also I would really love the option of going back to stock if needed. What I am asking is a away to reverse testfir.fir effects on the boot flags...

Please to enlighten me on these points 😀

Very good job with AEB extended. Now I have a 400D Mark IV.

You can put a pause of two seconds (for example) for the first shot? Is the stability of the camera.

Thanks.

Sergei

shubhankar.paul85, build 2011-01-27 doesn't have autoiso and ISOs lower than 100. Everything else is included from older builds.
testfir.fir modifies camera firmware. Wrong code and camera will be dead. It's probably simple to reverse the flags in firmware but i don't feel like i want to test it on my camera.
Josean0, i will add 2 seconds delay before first shot sometime later when i will have free time.

I have found small bug - camera is unable to start with card with old incompatible settings file.
Here is small (untested) patch - it ignores these wrong files.

Sergei, Thanks for the info. I would suggest you float the modified testfir.fir & someday if I am drunk enough or someone with a lots of spare bodies is bold enough, can probably have a go at running it.

😁 thanks !!

Hi,

Apologies if this has been asked before but... is it possible that this port of CHDK will allow scripts (timelapse, motion detection) for the 400D eventually?

Cheers

Hi guys - I asked this once before but didn't get any responses. Anyone know if this is possible?

I'm just trying to manage my own expectations and I would be gutted if I went and paid for a hardware solution if a software one was around the corner!

Cheers for any help.

It is possible but unlikely in near future...
Timelapse is easy to do , i can try to make it.
Motion detection is not possible with image sensor used in 400D.
(Well, it might be possible to make dumb motion detector from exposure sensor - and shoot on change of light conditions... Maybe.)

Timelapse is the function I am really after. I'd love to see this added...

Many thanks for your reply!

vatoz, thanks for the patch. I'm glad to see some one beside me start working on the hack.

Here is Extended AEB with 2 seconds delay configurable in info screen:

Thanks Sergei, and vatoz pour la patch 😁

The ability to take several frames is fantastic.

For cons, the setting remains the same all three frames.

Example with 3 frames : -3/100iso ; -1/100iso ; +1 / 100iso

For 7 frames: -3/100iso ; -1/100iso ; +1 / 100iso ; -3/100iso ; -1/100iso ; +1 / 100iso ; -3/100iso

You it is possible to make frames with different margins?

Thanks

Fantastic!!! 😁 😁 😁

There seems to be some bugs, so I have to turn off the cam from time to time 😎
It would be some more fantastic for me, if you could make a combination of extended AEB with a mirror lock. I think it would be the best, if the mirror remains locked during all the AEB-shots 😛 😁

many, many thanks so far!!!

I have added an automatic intervalometer.
You must configure it in menu and set dp button as a shortcut for it.
After starting you can disable it using main modeswitching knob (just turn it to another position, you will hear confirmation beep).

Anybody compiling this on a 64bit machine? I managed to create a build environment, but compilation always fails with a "relocation truncated to fit: R_ARM_PC24 against symbol..." error; I tried the "-mlong-calls" flag, as suggested somewhere else, to no avail. Other people with 64bit machines seems to have the same problem.

Hi, first of all thanks for the CHDK hack, I've been using it for a while and it's just one of the reasons I'm keeping the XTi instead of upgrading 😀

Regarding the latest firmware hack, automatic intervelometer works perfectly (kudos for this it's seriously a great feature), however, extended AEB doesn't seem to work for me. All the frames are taken with the same setting(no change in exposure setting, same shutter speed). I tried 3 frames, 5 frames with 1EV and the results were the same. AEB(not extended AEB) was turned off and I shoot extended AEB using the DP button(also tried pressing timer button then DP button).

Is there any setting I need to change before using the extended AEB function?

Thanks!

Vatoz - you ARE the man! I have been wanting this function on my camera for a long time and for you to add it within 24hours of my post is amazing. Thank you very much and also thanks to all the other devs who have worked on this.

Off to do some time-lapse - woohoo!

😁 😁

To repeater: Mine work is just extremly small fraction -i am just reusing existing codebase.
To spca888 : for me eAEB works in Tv Av and P . I am working on some other code for M mode - it will change directly Time value instead of exposure correction. +some aditional modifications - e.g. beep on completion ...
To eduperez: I am also unable to compile on 64 bit, so currently i have "summoned arm toolchain" to my old slow 32 NTB -where it works.

JoeNeptune

Thank you very much.
I am so impressed with all your talents.
I am new to DSLR but I learn fast.
What do you think would be good material to read to get me and my 400D up to speed?
Can multiple exposures be done fast and with good timing?
Is the shutter control fast enough to have it act as a stroboscope with out the flashing?
Or could this burn it out?

I cannot answer you on 64 bit machines, but I can tell you how I did it without re-installing a different OS on hard drive.
I have installed a Live version of Ubuntu 10.04 on an 8GB pen drive.
I have then installed the gcc-arm-elf compiler following the instructions on the WIKI as reported several posts ago.
It compiles very quickly on my portable which is a old Pentium M740 at 1.7 GHz, whitout any error.

Thanks vatoz for your contribution. I wasn't able to set the interval, I set an interval = 2 but than I need to shot manually. What I did wrong?
