S90 Porting Thread

[rachelkitty]

thanks very much, i'll give this a go.

In case you guys need any extra motivation, there are some kite aerial photographers who are already using the S90 to take aerial photos.  They are currently using clumsy servo motors to trigger the camera.  Once CHDK is available, they will be able to trigger the camera via USB pulse which is less subject to mechanical failure and also lighter weight.  I too am hoping to be using the S90 to take aerial photos before long.

Wel now, Michael L, who do you think Microfunguy is  ?

I will give you a clue  ... it is not possible to implement your ND constant-exposure override on the G11  

(and maybe not on the S90 if it has an ND filter).
That is because it crashes unfortunately.

Ha!  David!

A good man is on the job!

The good news is that the S90 has a real iris, so the ND filter issue isn't a dealbreaker.  I'm hoping the lens on the S90 is better than the one on the SD870, because there's too much corner softness at f/2.8 when the ND filter is out.  Consequently I've gone back to using my ancient, brick-like S70 when there's not enough wind to lift my dSLR.

Even if there's still corner softness on the S90, being able to stop the lens down a bit should help a lot.

Already at least 2 KAPers have built S90 rigs:  http://ostro.ced.berkeley.edu/~crisr/discuss/comments.php?DiscussionID=2554&page=1#Item_0

Good luck with the porting!

How's it going? Need any beta-testers?

[enrique_ifi]

Hi. I just wonder if there is some news about the S90. I will get a Canon soon, and having a CHDK is a deal closer for the S90.

If you need any help with beta-testing, i be glad to help.

[gsbergman]

Anything I can do to help get this into beta I'd be glad to assist with.

Hey Rachelkitty (or anyone), any progress on the S90 port?  I'm not a programmer but I will gladly help any way I can.

Same as Martlet: "... I'm not a programmer but I will gladly help any way I can."
It's difficult to know how we can do to help. I don't know how to start, i don't know if it's approachable to a newbie who never touch any code or programmation to start learning that... We just have a s90, and we want to help you... A kind of "for newbie developpers" could be great, but i don't know if we need two years of studies before...

No. It isn't. A developer is required. Without one, there is nothing you can do.

You need a good understanding of C and assembler to follow these directions. The level of knowledge required is equivalent to a year or so worth of university courses, and obviously beyond the scope of this forum and the CHDK wiki.

[shaltzman]

Thanks for your clear reply!
So we just can wait  and hope for an amazing result of CHDK into the S90!!!It will be great!
bye

I have emailed rachelkitty and battika to ask if they can upload their compilable code somewhere so that others can attempt to take this forward.

It would be a shame to waste their effort and have to start from 'scratch'.

Not much porting activity here anymore, as i see...
Anyway, unfortunately for my bankaccount balance, i could not resist to buy a S90.   
It has a "new" Firmware: 101a. The modified udumper from the G11 port was also working on the S90, so here ist the dump of the new firmware: http://www.zshare.net/download/74742478986973cd/

[Microfunguy]

rachelkitty and battika never responded to my emails but I am glad to say that ERR99 did (see above).

I am quite sure this camera will be ported very soon

Added the S90 1.01A dump from this post (8MB, from ERR99, dumped with a modified G11 udumper) to the drop.io - chdkdumps2 backup archive.

Thx to the 'dumpers' & uploaders !
