That's exactly what I'm trying to do. But for remote shutter release I need a script like the one here http://chdk.wikia.com/wiki/USB_Remote_Cable, which uses the shoot command, right? Or what did you mean, you tested it with remote?
Yes, i tested it with USB Remote Cable. I used the buildin Remote support without script.

SDMInst work but my cam save the pictures @ partition 1 not an partition 2 ;(
it is possible that the beta 5 is not compatible for 2 partitions ?
I think this happens because FAT32 Partition support isn't implemented yet.
I'll look for it.

Oh, it took me a while to figure out that enabling "Enable Synchable Remote" can be used to get remote shutter release without any scripts. :-) On the page here http://chdk.wikia.com/wiki/USB_Remote_Cable#Enable_built-in_CHDK_remote_support they only write about "Enable Remote" which needs a script.

Yes, wiki discription isn't very clear. I also misunderstood it.

It's possible to trigger the shutter by pressing USB Remote twice, But it "better" to use:

remote.bas (source: http://chdk.wikia.com/wiki/USB_Remote_Cable#Remote_Scripting).
Code: [Select]
rem [url=http://chdk.wikia.com/wiki/USB_Remote_Cable]USB Remote Cable - CHDK Wiki[/url]
rem Simple USB Remote Shoot script
rem Usage: Select "Enable Remote" in "Remote parameters" and start this script.
@title Remote button

while 1
    wait_click 1
    if is_key "remote" then shoot
wend

endSelect "Enable Remote" in "Remote parameters" and start this script.

Fixed Power Button

boot.c was wrong:
Code: (c) [Select]
// Power Button detection (short press = playback mode, long press = record mode)
// replacement for sub_FF834580
// ROM:FF861138, value 0x200000 and 0x400000 must be in reverse order, else detection is reversed too
*(int*)(0x24B8)= (*(int*)0xC0220110)&1 ? 0x400000 : 0x200000;

I look in the ixus 300 HS chdk wiki and find no information about how many megabyte have a raw picture file and how many bits /pixel the Sensor have.

please can somebody tell this or add to wiki ?
thats a important information because the series speed depend on transfer speed to SD Card a lot.

You can find all the specs and even a full review here: http://www.dpreview.com/reviews/canonsd4000is/
As far as I know, raw doesn't work on this camera yet, when I tried it the camera simply shut down. Keep in mind that this camera is very new and even if pixeldoc has done a great job so far and got lots of things working already (thanks a lot, btw) the CHDK port for it is still beta.

I'm still confused about ND-Filter. Canon Firmware does contain ND-Filter functions like other cameras. Maybe ND-Filter stuff should be disabled in chdk, dunno.

Running exposures without CHDK shows on certain end of range exposure Canon's firmware puts the ND filter in. Tricky. I exposed the same picture then with CHDK using similar settings - changed just enough to underexposure to compensate for the ND filter being out.

FIXED - I noticed this already but always forgot to fix it... default Battery min/max voltage was wrong. Change MAX Voltage setting to around 4100 (mV) and MIN around 3200 (mV) at chdk osd settings. Enable "Show Battery volts" and observe your Battery voltage after charging your Battery to get MAX value and wait for Camera to report Battery empty for MIN value (don't forget to post is here).
main.c

Have done this several times and I get the following:

4.6 - when fully charged
3.5 - thats when Canon meter starts to flash
3.3 - (dips to 3.28) the point when camera shuts done.

Beta v4


Have tested with a Ricoh CA-1 remote. Pretty much works, with 2-stage stepping, with sync enabled on CHDK. My findings are :

Able to "half" press shutter and get focus \ exposure and set override values set.

On shooting, takes the picture, though the camera display goes blank for 3-5 seconds then shows busy for 5 secs or so before going to preview or back to display depending on what has been set). Any ideas why this takes so long ? This is true for example when the shutter speed is set to 1/60th or other "fast" value. Pictures are exposed as per values for Tv and Av as expected. Its just the "black out" period the camera goes through.

If set to display hold after shooting, a half press does switches back to the live display. Fidley but works.

RAW Image files size i get ATM: 15,1 MB (15.935.616 Bytes). But the files just contains gargabe. There is still something wrong with raw buffer stuff.

@Beaver
Interesting result with your nd filter test.
I noticed the delay with remote shutter without using a script.
AFAIK this is by design. Have to test this with my SD900.

Beta v6

  • RAW stuff updated, camera does not shutdown anymore and create raw files but with invalid data.
  • PTP stuff added (some ptpcam chdk commands still cause error or shutdown)
  • read commit messages for more info
