Forums

Got a problem or a question? Please check the FAQ first. If you're still stumped, try one of these online forums.

CHDK Forum is the most active of the English forums and the very best place to ask questions and get an answer. It is monitored by most of the current CHDK developers. Postings translated to English via web sites like Google translate happen all the time and postings when English is not your native tongue are normal. So please go there first if you have a question.

CHDK-DE Forum is the forum for the German version of CHDK. CHDK-DE contains a few different functions from CHDK but the devs on both forums are working towards building both versions from a common base. The CHDK-DE forum is quite active and open to English submissions. Generally, only the German speaking CHDK developers tend to monitor the activity there but they know their stuff.

Dpreview forum used to be used most in the past (prior to 2008). There you can find the (English) history of CHDK's development.

Firmware versions in green are available in stable and/or dev for download
Firmware versions in gray do not have official CHDK releases. Check porting status here
For the development status of not-yet-supported cameras, see For Developers.

Under Development

Check out the "For Developers" page to see what progress is being made to port CHDK to additional cameras and firmware versions. You'll also find articles describing the porting process there. (Maybe you'd like to help?)

Sample pictures

We couldn't have done it without CHDK...
