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.

Michael L

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'.

ERR99

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 😀

fe50Added the S90 1.01A dump from this post (8MB, from ERR99, dumped with a modified G11 udumper) to the drop.io - chdkdumps2 backup archive.
[tt]http://drop.io/chdkdumps2/asset/s90-101a-7z[/tt]
Thx to the 'dumpers' & uploaders !

ERR99

Today i got some porting progress on the 101a firmware, i think... 😁

Microfunguy

Excellent !

At least there is nothing special about the bitmap overlay.

From now on, it should just be the tedious process of checking function and variable addresses, getting keyboard, movie, image-capture and possibly dual-partitioning working.

Don't know if you bothered about supporting the firmware-update method, personally I do not.

Hey Err99 😁

Nice to see U here ! ! !

You will not regread it - the S90 is my favorite little "takewithme" Cam.

But my Firmware is the 1.00C - so I can`t use your dump.

Please be so gentlelike and bring me in 😀

ERR99

Porting is going on very well. I got now the keyboard & jogdial stuff up&running, so i can navigate through all the CHDK menus.
Exposure overrides looks also so good. Dual-partioning is allready ported, but i have to test ist. There is still enough to port,check, and debug, but until now it looks good. 😉

When the port for 101a is finished, i will take a look on the 100c fw... :😀

mercurio

hy,
i'm new to this and have one question, i tried to get my s90 101c firmware the way described by err99 but the only thing i get after removing the card from the cam is a unformated card. (the af lamp lights and i let the card in for 2 min, batt out, card out, ...)

anyway hope err99 does god progress in porting 101a (hope it will work also on a cam with 101c)

cheers
