A460?

I saw on the wiki that there were several proponents for a port to this camera but no action has been taken yet. I have an A460 at home, perhaps I can help to dump the firmware and/or test it.
The same build could probably be used for A450 since the only difference is 4x optical zoom as opposed to 3.2x in A450.
So, where do I sign up? :)

I nearly forgot, I don't have a phototransistor but I have built a remote receiver for the PC with Girder. I don't remember OTTOH what schematic I used (it's Ivan something) and is based around a common infrared receiver with 3 pins connected to serial port. Perhaps I can use that as a starting point.

Hi,

You can get A460 1.00d dump here: http://www.zshare.net/download/6802925ee9ba85/
I'm already working on porting.
First beta will be probably posted here today in the evening (after few tests).

You can get first beta binaries for A460-1.00D here:
http://www.zshare.net/download/73083465bd44f0/

The port is based on allbest build with additional modifications.
Your help with testing would be greatly appreciated.
So, please report as many bugs as possible :)

"Video Parameters" menu (movie_rec.c) is not implemented yet.
"USB remote shooting" is not implemented yet.
Functions related to getting information about space on SD card are wrong (GetFreeCardSpaceKb). - fixed

Great!! :)
Thank you for porting chdk to the A460, is magnificent!!

I have trouble with the CRW images, I can't open them. :(

Using bracketing the camera shuts down

Cheers and Thank You

Could you please specify what types of bracketing are not working?
A460 is low cost camera, so will see, if it is possible to implement all enhanced CHDK features  ;)

It seems that A460 have new (for CHDK) 5 Mp matrix (RAW size is 0x63FF60 bytes, matrix 2664x1968).
A610/S2IS have RAW size 0x644C40 bytes, matrix 2672x1968.

I know, I included following code to raw.h
#elif defined (CAMERA_a460)
#define ROWPIX 2664   // for 5 MP 1/3" sensor size
#define ROWS   1968   // for 5 MP 1/3" sensor size

Thanks for confirmation of my assumption.

Unfortunately, I have not seen your code :(

But none of RAW converters supports this RAW.
