SD980 beta release

[trogdor]

Just out of curiousity, does anyone use Virtual Machines? If one person got a nice ubuntu development environment set up then we could all share it, and someone like me (coder without a LOT of free time, but want to help where I can) might be able to make more substantive contributions. I do all my work in VMs.

Just a thought.

I also took a shot at starting a port for the v1.01C firmware:

If anyone with more CHDK/ASM experience can help complete it, let me know...

My is 1.00d, Who have the CHDK for it?

From what I can find, work has not even started on this revision.  If you have any coding skills, you might want to start with a firmware dump.

It would be great if you could post the output from the ver.req in this thread if you used that method. How exactly did you get you version info?

[openuas]

So among the other things todo I managed to

1) Get the Crosscompiler tool chain working fully from source scratch on my 64Bit Linux.  
2) run IDA on my temporary WIN partition.
3)  I have the 100C source
4)  1.01c Firmware dump

Now onto the next step.... reading more of the Wiki and post

Just FYI: IXUS200 SD980 v1.0.1c porting info will be in:

OK, a dilemma.

I currently use  an IXUS 70 for RC aerial photography, I wrote my own interface for a PIC12F675 to use a RC servo channel to output USB pulses to control the camera via CHDK.

I would like to switch to a camera with a much wider angle, it becomes less critical to point the plane at what you want to take a photo of.

This IXUS200\SD980 camera has the equivalent of a 24mm wide angle in 35mm terms, so it would seem a good choice.

However how can I work out, before purchase, what version of the firmware is in the camera, it would not be worth purchasing without the ability to run CHDK ?

[openuas]

srnet, well there are only so much firmware versions.... Indeed it is a gamble which I took to discover my firmware was not yet supported   So I decided to take development into my own hands and start working on it . Now that the OBC2010 Challenge is past I can devote time to the 1.0.1c firmware again. And if I can make one firmware no doubt I can make it for other firmware versions also. But that is for the future...

The sooner you buy the Device the higher the chance it is an older firmware and more change of getting a patched one soon...

BTW great if you could post a link to your PIC to Ixus 70 hardware project of schematics.

Would there be general interest in seeing the code for a RC to CHDK remote control ? Easy circuit, single 8 pin IC (12f675) written in Mikrobasic which is free to use for the 2K PICs. All you need is a PIC programmer.

Certainly would.

Could you recommend and give links for the software and suitable programmer ?

[srnet]

There are plenty of easy to make DIY PIC programmers out there, either connected via the parallel port or serial port. This is an example;

http://www.semis.demon.co.uk/uJDM/uJDMmain.htm

Run an eBay search on 'PIC programmer' and you will find several from around $15.

Myself I use a PicKit2, fairly cheap and easy to use.

I will go through the code I have to make sure its legible, its written in Mikcrobasic for a 12f675, and failrly easy to amend.

I have CHDK running on my IXUS 200, but one thing is puzzles me.

It does not power on\boot when the power button is pressed. The card write protect switch is set and the power button works as normal in non CHDK mode.

It does however start when the playback button is pressed, this starts CHDK and the autorun script runs.

Its not a serious issue since the script waits for a USB pulse and takes a picture at which point it changes from playback mode into record mode.

Should CHDK be starting when the power button is pressed ?

...Should CHDK be starting when the power button is pressed ?

The camera always start in playback mode when CHDK is enabled, this is the normal behaviour on cameras without a mechanical switch for playback/record mode selection.

* When powered on in playback mode, just press the shutter button full or halfway once to switch to record mode
* To turn the camera on directly in record mode, try holding the POWER button for ~1 second

You don't need a (autorun) script to start/run CHDK...
