Quick question, will any of the ports of the S90 work with the new S95 since I've read the only difference is the HD video and a few extra scene selection modes and the HS.
No, absolutely not. Every model needs a new port.

An option that I would love to see more than any other in chdk!: turn the camera on immediately when pressing the power button--and not go to Play mode!
  I've missed so many shots because the camera went to play mode after the power-button press delay, and then I think I didn't press power and I push it again only to turn it off, then have to wait again before it accepts an ON commands...etc.  It's a nightmare and I wonder why the CHDK standard is to go to play mode: I can go to Play directly if I want to by pressing the Play button.  I don't need chdk for that.

  I know this option is possible, because the early beta versions for the S90 had a "bug" where the camera would go directly to Shoot mode, and that was changed later on.  Please bring back this operation mode, it was great!:D

if your interested in a discussion about this, see here: http://chdk.setepontos.com/index.php/topic,3994.msg42107.html#msg42107

A patch as discussed there appears possible for S90 (from a quick peek at the trunk938 source)

For the moment, to boot straight to shooting mode, press and hold try pressing and holding down ON/OFF until you see the CHDK logo appear or hear the lense extend (~ 1 sec on my ixus 870is)

HTH,

wim

[edit: formulated more carefully - can't be sure if long press works on S90 ]

[edit2: added patch suggestion (untested, of course !) ]

To patch the boot behaviour, the following line needs to be changed in trunk938 from
Quote
*(int*)(0x254C)= (*(int*)0xC0220128)&1 ? 0x2000000 : 0x1000000; // replacement  for correct power-on.
to:
Quote
*(int*)(0x254C)= (*(int*)0xC0220128)&1 ? 0x1000000 : 0x2000000; // replacement  for correct power-on.
the code is identical for all 3 firmware revisions, locations are as follows:

in platform/s90/sub/100c/boot.c  ->  line 134
in platform/s90/sub/101a/boot.c  ->  line 143
in platform/s90/sub/101c/boot.c  ->  line 131

hi, i'm new user, i ve a question : what's about Aperture and Speed in S90 with CHDK ?
does it have fully steps ? and Aperture limited at f/16 ?
i'm confuse between LX3 and S90 (chdk), LX3 has only F/8, not enough for my demand, i want to shot at low light, f/16 so great...

f/16 in low-light? this makes no sense to me. in low-light you woul use the highest F number available. that is f2 on S90 (don't know about LX3).

anyway, S90 hass full manual controls. I don't know what are the hardware limits, but in some tests I guess they are better than firmware imposed limits (shooting at 1/4000s or f11 seems to work, but I'm unable to cientifically prove that. it looks like the photos are different from 1/1600s of f8 on the same conditions).

I am resurrecting this thread, as SDM allows for excellent 3d sync.
Just wondering if anyone has tried to capture the RAW buffer to the SDHC card - on any CHDK camera ? If we can get some capture on the S90 with SDHC - say a window of 720P RAW, we can get 1080p on the S95 and newer CCD cameras using the supported SDXC cards.
My interest in the S90, is in its CCD sensor.

Re: S90 Porting Thread - user selectable <ALT> button
« Reply #397 on: 16 / May / 2014, 00:31:35 »
I'm looking for an S90 owner willing to test a simple CHDK patch.   Per this thread : 
link> S95, S90 alt button
a user selectable <ALT> button can be part of this port if someone is willing to test the patch.

Download links for a test build for the various S90 f/w versions :

link> s90 1.00c
link> s90 1.01a
link> s90 1.01c

TIA
