While the Ixus 125 is very well tested and has a minor PtP problem regarding
the Vertical PtP Resolution.
Are there details of this problem posted somewhere?

Also the Ixus 265 and Sx600 are capable of Wi-Fi Remote Shoot and Wi-Fi Live View
on IOS and Android smart Devices, they are also are Discounted.

And the Ixus 275 and Sx610 are capable of Wi-Fi Remote Shoot and Wi-Fi Live View
on IOS and Android smart Devices, they are the current canon models
Just so it's clear, none of these cameras are currently supported by CHDK.

When I recently tested a Ixus 125 I noticed that the PtP resolution is about half
what is in the cameras viewfinder i.e. the top half only is displayed.

I also recently tested a Ixus 240-101a using test build #3 and there was several
problems, I will re test and post the results in more detail.

Is the Ixus 240-1xxx Source Code for the test build #3 available somewhere ?

Also is it possible that the  Ixus 240 capt_seq.c file has some or multiple
errors, as capt_seq.c seems to be the most difficult part of any CHDK port.

Hi HH and reyalp.

Thank you for detailed description.

Probably, Ixus 265/275 will not be good solution for me, because I need camera for archive papers scanning, some old books, i.e. some case of book scanning. That means, RAW format is critical for me because JPEG has some compression artifacts around text. Also, looks like API for these camera is closed, and I can't use it with my own software.

And Ixus 125 costs almost twice than Ixus 240 :( Probably, I will need to buy even 4 cameras for two scanners in this summer, i.e. cost will be important thing. I see fast answers in this thread and good support. Sometimes, it's more important than stable work.

I can use very limited functionality for first time, even without much ptp control. I just need:
1) ability to save RAW files(CR2 or DNG - not important) additionally to jpeg on the memory card
2) live preview with any quality via PTP - aspect ratio issues is not important at all
3) send 'shoot' command by PTP, i.e. ability to shoot and save jpeg and cr2 to memory card
4) ability to call get_image_dir() and get_exp_count() Lua script commands via PTP
5) download jpeg and cr2 files by PTP to computer and remove they from memory card

Could anybody please to check it on Ixus 240 ?

FWIW, about two month ago, markvandenborre selected the ixus160 (elph160) as potentially a very good camera for book scanners (not too expensive and currently available in stores).   After a few discussions on the CHDK IRC channel,  adong joined the porting effort and started the ixus160_elph160 porting thread.

They have made really good progress in porting this camera,  but its a new DIGIC4+ camera and they are currently stuck on getting RAW images to save properly.  However,  one of the most experience CHDK developers & assembly language experts - srsa_4c - is now assisting them so there is a good chance it will get sorted out shortly.  (fingers crossed).   

You might want to take a look at the porting thread and maybe contact Mark/adong via PM or on IRC?

edit :   I should have also mentioned that adong bravely started the port "blind" until  amavroidis generously sent him an actual ixus160 to work with.  amavroidis is working on a multicamera 3D scanning rig AFAIK.

Its looking like the problem is possible "multiple errors" in the
Ixus 240-101a and Ixus-102a ports and I am not at the halfway point yet.

101a and 102a are both in the autobuild. If you can describe the problems, it is possible someone may be able to help fix them.

I'm experiencing manual focus (set_mf and set_aflock) problems with my v1.3.0-3274 CHDK IXUS 240HS (102A).

Let me start with saying that locally (on cam) I can do a manual focus override, by going into the CHDK > Enhanced Photo Operations > Override Subj. Dist. [on][   176]. Taking a photo confirms focus override. Also RemoteShoot via CHDKPTP confirms that focus is set and stays at 176.

"Man Focus" button (turns green) in the quick menu, also works as expected.


However, when I do the following over CHDKPTP:
Code: [Select]

con 2> luar set_focus(1)
con 3> luar set_focus(65490)
con 4> rs

I'm experiencing manual focus (set_mf and set_aflock) problems with my v1.3.0-3274 CHDK 220HS.
According to the test results reported here : Google Docs MF Test Results your camera should allow CHDK controlled MF with and without using AFL or MF modes.

(ref : Setting focus from scripts or menus)

Doing MF from the CHDK menus does not invoke AFL or MF modes.  It just does an MF set.   Your issue seems to happen when using AFL or MF ?

v1.3.0-3274 CHDK 220HS.
That build is from December 2013...
I'd suggest upgrading to a current 1.3 or 1.4 release.
However, upgrading will still not solve the remote shooting issue, as the ixus220 port doesn't yet have filewritetask support.
A quick look tells me that the a3200 likely has the same fwt code, so fwt support can be added easily to this port.
Are you willing to test that? If yes, please tell us your camera's firmware version.

As for subject distance override, please re-do your testing with a recent CHDK release.

Note that the screenshot looks like a touch screen camera (IXUS 240, presumably). IXUS 220 is not touch screen, AFAIK.

If it's confirmed as 240, I will move the posts.
