Anyone on 1.01b been able to get SDHC cards to work with the latest beta?

I have CHDK on my 4GB SD card with a single partition, CardTricks gave a warning while formatting, I chose to ignore, and it's working.

Which uBasic commands work with the A590IS?
Quote from: PhyrePhoX on 19 / November / 2008, 18:25:55
uhm, all of them!?

I tried uBasic scripts on my setup, but most of the time it says 'Unknown statement'. I am using the latest 1.01b build. What's wrong with me, please anyone help.

P.S. I have just figured out that whenever I save a script on my card using Notepad or Notepad++, 3 bytes of extra characters are added to the beginning of the script (Hex: ef bb bf). Once I have removed those 3 bytes using a hex editor, scripts are running perfectly. Anyone has any clue why these extra bytes are added? My setup: Windows XP, 4 GB SD, Editor Notepad++, Card Reader.

You might need to save the script as filetype "all"!

Hi,

A question about vga frame rates and chdk: the a590 is stuck at only 20fps at vga resolution while the a570 can do 30fps. why would canon do that  >:(? can chdk go around it and enable 30fps (or better!) frame rates at vga resolution on the 590?

also, people who are currently using the 590 and also has experience with the 570: is the 590 an actual "upgrade" to the 570 in terms of performance, quality, and durability (ignoring the extra megapixel which is not an incentive for me)?

Thanks

My sincere gratitude to all involved in CHDK development. I am so happy to have my A590IS working on CHDK. Just a little concern though, not about CHDK, but about the particular individual camera that I possess.

By doing firmwire version checking I get -

Canon PowerShot A590 IS
P-ID:3176 NT D
Firmware Ver GM1.01B
E18
Jan 24 2008 20:41:51

Adj. Ver.011.002
ZoomLensError
2008.05.23 20:44:12

My concern is about this 'ZoomLensError'. I have not seen anybody reported anything else other than 'NoError'. After loading CHDK, I have selected to show 'Miscellaneous values' on the OSD, I was surprised to notice that my camera lens zooms only in the range of 1.0-2.2X (5.8-13.1mm or 35-79mm EFL). Please correct me if I am wrong, I was expecting a zoom range of 1.0-4.0X (5.8-23.2mm, as shown on the lens). Also I have noticed that it has 8 step zoom (0-7).

Does this mean that I have got a faulty camera? Has anyone else noticed any such discrepencies? Can I claim a replacement/repair while still within warranty? Any idea would be highly appreciated.

Thanks to CHDK again, without it I would have never been able to discover this issue.

zoomlenserror just states that some time ago (probably may 23rd) your lens got stuck when it was protruding. maybe you accidentially powered the cam on when it still was in the case or the like. nothing to worry about.
the zoom-range on screen display item was fixed in the latest revision by the way, just get the latest autobuild and be happy with your a590 :)

The average battery life CIPA (Camera & Imaging Products Association) values for the A590 are

- 200 shoots with AA Alkaline Batteries
- 450 shots with AA NiMH Rechargeable Batteries

I was getting ~270 shots per pair of alkaline cells before using CHDK.  New 2650mAH NiMH cells were very disappointing but it was after their first charge, so I'll reserve judgement  for now until they've had a few cycles. 

I'll have to start a battery diary as I've forgotten picture numbers -- batteries don't last near as long with CHDK fitted, but as the FAQ on battery life stated, I've spent much time in the CHDK menu in record mode...  Also been taking many five-shot exposure bracketing (2/3 step) sequences for HDR, that would suck battery life too.

I have IS set to 'shoot only', rarely take flash photos, and haven't been taking much other trouble to minimise battery usage.  Alkalines are Rayovac brand from USA (bulk pack 48 for AU$20) and NiMH are Duracell, made in Japan, with a Duracell smart 4 cell 3 hour charger.

Other point is that now I have the CHDK battery voltage display I can now take the alkaline batteries way further, so some dozen or two shots and much CHDK menu time (perhaps an hour or more) was with the red lobatt symbol flashing.  I think the camera shutdown when the voltage fell to about 2.2V on alkalines.

And I'd also like to add a big THANKYOU to the porting team for the A590 CHDK, much fun exploring the extra capabilities on my new camera.

found another bug.

the dark frame subtraction option does nothing, even if i set it to off it still shoots a dark frame

=/

i wanted to shoot some star trails tonight, but looks like i won't be =(

with dark frame subtraction on, there would be gaps in the trails from where it stopped to shoot a dark frame between exposures.

anyone else have this problem?

I have the same problem. I know i configured it correctly because I also have a SX100IS and It fontions correctly.

I got 500 shots out of Sanyo eneloop 2000 mAh batteries while doing a time laspe with a intervalometr script. After there was still around 20% left.
