Thanks for the quick reply waterwingz!
Looks like I'm going to have to bite the bullet and get back on ebay.
I understand the time pressure.   Would still be nice to get a memory dump if you can spare ten minutes to set things up and do that?

If you are using ebay, you might want to see if the seller will take a picture with the camera he is actually selling and email it to you or post on a file sharing site  You need the original image.  Once you have that,  use the ACID utility to discover the firmware version of the camera.

Hi,

I tried the current 1.3 alpha from the download section on my recently purchased Ixus 240. I tested some of the scripts that I used on my older Canon camera - they seem to work fine.

I am planning to use the Ixus 240 for aerial video recording & photography and I wonder if there is a solution for getting a live video signal in record mode. So far it looks like the composite video is only enabled in playback mode. So far I didn't get any useful information when searching the web. Is there any experience here if that can be done?

Cheers,

Ulrich

Unfortunately, most modern canon cameras do not support video out in record mode. No one has yet figured out how to bypass this. It may or may not be possible, reverse engineering would be required to find out.

You could theoretically use PTP live view, but this would require a USB host capable device connected to the camera to convert the video to something you can transmit to the ground. Something like a raspberry pi would give you composite or HDMI out. The frame rate would not be terribly good (maybe 10 fps) and you'd have significant additional power draw. Other similar SBCs should be able to do the same thing. Most Arduino and similar micro controller systems probably don't have the processing power to do it.

It may eventually be possible to send the live view over wifi instead: http://chdk.setepontos.com/index.php?topic=10724.0 but I suspect the range of the cameras built in wifi would not be good. Perhaps if your grounds station had a high gain antenna with tracking...

I continue to have a great deal of trouble understanding your posts.

The wrong colors are due to the bitmap palette functions not being implemented in your port (vid_get_palette_type, vid_get_bitmap_active_palette etc). These are pretty easy to implement, I will try to post a test build if no one else gets to it first, but I am very busy at the moment.

Regarding "sd card unlocked" I assume this mean you do not have CHDK loaded. chdkptp only works with CHDK, it will give you the error shown in the screenshot if the camera is not running CHDK. Improving the error handling is on my todo list.

The romlog doesn't tell me anything useful, it's not in a task CHDK modifies.

edit:
The palette stuff looks like it's implemented for this camera. Possibly the type is wrong. If you can post a chdkptp "quick dump" from the live view debug tab, I can check it.

Thanks for sharing your thoughts, reyalp! I will do some more searching to see if a reasonable solution can be done.

Best,

Hi All,

I now have these versions of the Ixus 240:-

Ixus 240-102a  Compiles Ok, Boots Ok, Runs Ok; but has some problems.
Ixus 240-101a  Compiles Ok, Boots Ok, Runs Ok; but has some problems.
Ixus 240-100c   Dump Ok, Very similar to 102a and 101a, Offsets; Most Ok, Compiles Ok.

but fails to Boot. [CHDK ver 3254]

What is the next step in regard to the Ixus 240-100c.

Edit #1 for the Ixus 240-100c

After some Error checks, I found that a droped "F" error in boot.c and a few other "Typo's"

So the Ixus 240-100c  now, Compiles Ok, Boots Ok, Runs Ok; but has some problems.
It now has very similar in behaviour to 101a and 102a.

Did you actually try to run all three versions of CHDK on the same camera?
