don't think so:
SD1100/ixus 80 doesn't have "#define CAM_MULTIPART = 1" in trunk 627 source,
and no multi partition support means no cards > 4 Gb (unless you force-format them to 4 Gb @ FAT16)
This option can be applied only to VxWorks cameras.
I looked into sources:
ixus80 1.01a - no multipatition support;
ixus80 1.00c - no multipatition support. In sources present also largedisk.c (not included in Makefile), which begins with:
Code: [Select]
// -- ---------------
// SDHC-Boot-Support
// -----------------
//
// This is not supported unless I recieve a large SD card
// ...
//
// :P
//
// chr

Maybe somebody must send large SDCH card to chr.  :D

Today, tried "ultimate intervalometer" script; appeared to do nothing, then gave a very brief message before turning off.  The message looked like it might be "watchdog timeout" but I'm not sure.

Next, tried "intervalometer" script found on the net: Bingo! Started snapping photos.  I set the interval to 2 seconds but it looked more like 4 seconds so maybe that is as fast as it can go.  I'll do more testing.

Mainly, just wanted to say thanks to all developers for a super cool tool.  Next up: fasten it to my glider and do some aerial photography!

hi, i'm new to chdk.i just bought ixus 80is last week.i'm so excited that ixus 80is is chdk supported  :)

i've the same problem like you Old Farseeing Art, when i tried the "ultra intervalometer" script, there is brief message and then the camera turn off. i wonder what is the problem. can anyone explain it?

Old Farseeing Art, can u give me a link of the 'intervalometer' script that you tried ? thanks.

anyway, thanks to chdk teams,chr and chdk community

I don`t know if this is a bug, or a limitation of the Cam:

I played a bit with the shutter speeds and long exposure and the cam can`t give me more than 15 sec. exposure. If I chose 20 or more it give me only 15 sec. limitation or bug?

Neither camera's limitation nor a bug - user's limitation  :D

The Canon OSD don't know the CHKD overrides, therefore i reports only its "own" (or the max. known) values (also the same with the EXIF data in the image). You can enable the CHDK OSD, it shows the overrides you have set - then you must try, what the physical limit of your camera is (e.g. you can set shutter speed to 1/100.000, but your camera can't do this extrem timig, the limit for your camera should be somewhere around 1/5.000 or 1/10.000s).

And I thought yesterday about to add also "or user limitation?" why I didn`t do that? :) ok...

I see a difference between 1/10.000 and 1/20.000, so it is able to do more than 1/10.000 (tested with a drop of water, often ;) )

The cam can really do 64secs. tested this yesterday and it is very nice for astronomy works!

Hello,is it possible that the "set_led" command is not available (at the moment?) for IXUS 80IS ?

For bpboyz: my apology for not seeing your request until today.  Here is the script I have been using.  As you can see, it has mutated; it started out with calcs for minutes/seconds but that was removed and it just shoots about every 2 seconds.  Then I added usb control to turn the camera off on command.  I use this for aerial photography and turn the camera off during landing to protect the lens, etc.  This is mainly something to show how poorly to write scripts. :haha

rem Interval shooting with usb control

@title UsbFastInterval
@param a Shoot count
@default a 50000
@param b Interval (Minutes)
@default b 0
@param c Interval (Seconds)
@default c 2

t=10
sleep 1000

print "Shoot 1 of", a
shoot
for n=2 to a
    sleep t
    print "Shoot", n, "of", a
    shoot

wait_click 1
is_key k "remote"
if k=1 then gosub "turnoff"
next n

:turnoff
shut_down
wait_click 2000
return

end

Hi I just tested the CHDK revision 688 (released yesterday) in my SD1100 1.00c. Before this I was using CHDK Rev 649 with no problem. Some of the new features added in the recent revisions are cool.

I figured out some odds, when the camera is in preview mode. The zoom in/out knob responds slow and needs to wait until the blue light of print button turns off before taking any action. Other buttons such as Disp, left/right/up/down shift etc. also do not work promptly. You never know how long you need to wait.

The motion detect script once had frozen the camera and needed to take battery out for resetting. I suspect some bugs are responsible to cause the slow operation of the buttons. It seems, the camera reads volume of data from the Disk in every operation due to some "memory release" routines added recently. I use 4GB SD card (not SDHC).

Please share if anyone else has similar experience or solution to the problem.
