some bugs :

Card: 4GB sdhc, formated and maid bootable with cardtriks, Fat16

I have'nt green color in R-G-B histogram,( just transparent white)
In osd, when i run a script, nothing printed on mini console

requin

I was wondering, would it be a hard thing to do to implement time-lapse function to the chdk 1.02b-version? I would SOO need it and would be very grateful.

acid2000

The colours should be fixed in the next release. Still working on the console

savalangh

thanks to acid2000,

I'm not a programmer, but i think, i can work on sum scripts
I'm reading ebooks about ubasic, and start working on scripts soon, 😀

Timelapes and motion ditection are 2 great scripts, I am going to working on these 2 scripts. as soon as i understand about programming 😁

First, I now have to use the playback/shoot button to turn my camera on - not the on/off button.

On my camera I can use the on and off button.

OK, that seems to be working now.

To get to shooting mode, I now have to half-press the shutter.

Correct, you should also be able to press the mode change button

No - it seems to turn the camera off.

The shortcut button invokes <ALT> mode fine, with "Default Script" in the bottom left corner of the screen.

Thats correct

Menu button brings up the Main Menu, but the only way I seem to be able to get rid of the main menu is to toggle to playback mode, then back to shooting mode. Then I have to press the shortcut key again to reactivate the OSD. With the 630, another press of the menu key turned off the main menu.

This I think to do with the refresh bug. I haven't found how to fix this yet, any help is greatly appreciated.

Wish I could help, acid, but I'm no software developer 🙁 Again, though, I appreciate all the work you've done on this FW release.

I hve enabled symbols, but they don't show up. Also, when I go to a sub-menu, the previous menu stays on in the background.

This bug I think is the reason why zebra and console output is not displayed correctsm the second point is the refresh bug. These two bugs may be related.

I was wondering if the symbol problem was because it looks to the FAT32 partition for these files, and the grids. If so, how can I copy them to that partition before (or after) installing CHDK on the FAT12 partition?

I have enabled superfine mode in the CHDK menu, but don't seem to be able to activate it from the Canon Function menu.

I could be wrong but I don't think it does, just take a picture and look at the file size

OK, I'll give that a try.

Fredrock,

Any word on when a 102C FW will be worked on?

I don't think anyone with 102C has started yet. It isn't too difficult but you do need to be a software developer.

WHY!!! Ahhhh im not a software developer 🙁

Rick OBanion

Not having any luck with this. If I do it regular, I get an error when doing the 'Firmware upgrade'. If I make the card bootable, the camera will not power up.

Using a Kodak 4Gb SDHC card with the SX10 102.b CHDK and the SX20 diskboot.bin file.
Did everything through Cardtricks....card formated fully to FAT.

Rick OBanion

Okay..sorta have it working now. Did the diskboot file swap without CardTricks and it worked better. Now just having some other issues I will try and work out.
Cannot create badpixel.bin, menu seems to freeze and cannot get any overides to work

I think the only way to make one *now* is to follow the guide on top off page 32
"******** CAPTURING DNG IN CAMERA ***********"

That worked for me.

Thanks for acid2000 for your work!!!

acid2000

WHY!!! Ahhhh im not a software developer

Because porting CHDK is non trivial and infact quite hard, even for an experience programmer. You need to be able to understand the output of a dissasembler which many people just cannot do. In addition CHDK is written in a computer language that most new software developers are not taught. All of this is compounded by the fact that testing it up to a point is performed by blinking an LED, a slow and tedious process.

Any person with the skills, or who wants to try aquiring them really should have your model of camera, otherwise everything has to be done blind. At the moment not many people do. All this is compounded further when you think that no one is paid to do this.

Look at how long it has taken to get this far with the SX20:
100f - October - December last year
102b - April
100c - ?

Your not the only one who has been in this position, in another thread some members were trying to buy a camera for some so that they could port it. The good news is that the work that is done on the SX20 means that other SX20 revisions become easier to port - a lot easier.

I hope all this answers your question.

Lectrichead,

Try deleting all the files on the card apart from DISKBOOT.

If it still doesn't work can you tell me if any folders do actually get created?
Have you tried a different memory card, I have one card that CHDK just doesn't seem to boot of - in any camera.

No luck - tried a different card, tried deleting all files off the card except DISKBOOT.

I will get back to you on the folders created (and also I have to try the other tip suggested - taking the batts out).

******** CAPTURING DNG IN CAMERA ***********
ok, just follow these steps,
1- take one raw image with camera and export it to a folder

2- Download show_bad_b.exe from the link and copy it to above folder:
http://chdk.wikia.com/index.php?title=Special:Outbound&f=Badpixel_removal&u=http%3A%2F%2Fewavr.nm.ru%2Fchdk%2Fshow_bad_b.zip

(you can give some information about this in the forum, http://chdk.wikia.com/wiki/Badpixel_removal#Links)

3-in command line type this string, with the name of raw file in step 1:
show_bad_b.exe <CHDK_RAW_FILE_NAME>

4- in same folder after this process you can find the file : badpixel.bin

5- copy it to CHDK folder inside the memory card

6- now you can adjust the DNG format in chdk menu and take DNG photos 😀

I downloaded this and extracted to same folder as my RAW image, but the prompt window opens and closes immediately. Don't get a chance to do anything...

Try this: Start - Run - Cmd
Now you should have a (black) window to work in. If you try the command here you can see any messages that may turn up.

acid2000

Can anyone with the 100f tell me if you can see the script console output -- see this image for example:

http://chdk.wikia.com/wiki/File:Work_of_script.jpg

For those in the know you don't need LUA support for this, you can use the DEFAULT.BAS file.

Thanks..that got it. Had to remember how to do change directory in cmd...getting old..lol
All set now 😀
Going to compare superfine with RAW and see what the diff is.

Have you tried a different memory card, I have one card that CHDK just doesn't seem to boot of - in any camera.

Wiped the card, tried from scratch with just DISKBOOT and making it bootable and switching on write protect tab. Still no luck (stuck on the CHDK screen - just the text with a red box behind it, no logo graphic).

Tried a different card, same.

Switching the write protect tab just returns the camera to normal.

The folders it creates have no files in any of them. They are; BOOKS, DATA, EDGE, FONTS, GRIDS, LANG, LOGS, SCRIPTS, SYMBOLS.

acid2000

Well it's started the main task then which is good.

Try resetting your camera to factory defaults. My guess is that its reading a value that it expects to be within a certain range and its not.

warfarefx

Lectrichead,
When you get the red box with the text in it, did you press your shutter button halfway. I see the same thing until I press the button, then normal screen appears with new stuff like battery charge status, etc.

Ah, there we go. Yea, that does it, thanks!

I hope that the "shutter button halfway" after it's powered on is something that can be changed so it doesn't have to do that, at some point?

The OSD menu seems to stay on the screen when I bring it up, unless I mes around with a few of the settings that seems to update the screen.

Now to try all of the other functions. Great job so far guys.
