Thanks to all that have contributed to this effort. I was not equipped to contribute - but I feel inspired now to learn how to do it - I have been following the progress daily for many months.

Thanks!

I would like to take this time to thank everyone for all their hard work.  I can't get enough of my SD790, now that I can shoot RAW.  I don't know if this has been discussed, but, Picasa can read the RAW files, regardless of the extensions.

ehmu, how exactly is the patch used?  I found no indication as to where to put it.

The MDFB-080716 motion detection script works just fine with my SD790, which is an older script.  The newer script MDFB-080914 gave me error messages and would not work at all.

Telling us *which* error message might be useful.

The patch in #259 has already been applied to the trunk AFAIK.

I managed to fix extended video quality control now and
also fixed a bug (camera freezes) for fast EV control (half shoot + jogdial).
Added to CHDK trunk (changeset #867), already included in chdkde/fe50t since changeset #210.

To get the latest binaries for the ixus90_sd790, always download the package from the official CHDK Autobuild Server.
Here you'll see what patches are already commited: SVN revision log

MDFB-080914 (WITHOUT VideoButton) does work on my ixus90 in shoot & video mode.

Lua_library_test seems to be ok. The log just contains PASS and NA, no FAIL.
Connecting the cam to an USB port always causes the cam to focus, but I just managed to make it shoot once (~1 of 10 tries). I guess I am to slow, a real remote cable could help.

Can somebody test SD cards >4GB?
I don't have one. (When I grew up, nobody could imagine who would need that.)

My ixus 970 reference port hooks task_ExpDrvTask, which the ixus 90 does not. What is its purpose? How should it be tested?

The patches contained my local source code changes against the CHDK code repository.  I am grateful that fe50 adds them to the CHDK subversion trunk, as I don't have permission.

You should be able to test multipartition on a smaller card if you want.

HAHA, so true. I do remember when a 32 bit RISC machine with 32 megs of memory and a couple gigs of persistent storage (never mind unimaginably small solid state) was a $thousands dream workstation :)

It is for extra long exposure (> 64 sec) support. Some cameras also need this for extreme short exposure (e.g. SX10, although I haven't gotten around to putting this in the trunk yet)

I just downloaded the latest build and tried again with the 914 Motion Detect script and it now, works fine.

I reworked my Ixus90 code changes:
  • ultra long exposures (>64s) added. (I wonder if I will ever use it  :blink:)
  • multi partition support adapted and tested.
  • hooks in boot process adapted. (used the magical mystery style "*(int*)0x1930 = (int)taskCreateHook;")
  • DNG colormap changed (S5 was set, changed to colors that most(all) 10MPixel 1/2,3" sensors use, but didn't really test it).
  • remote zoom steps corrected (nTxtbl).
  • uBasic set_led
  • some cosmetics and clean up.

If somebody out there can test this, please give some feedback.
Kind regards   ::)
