Porting process

→ Porting the Ixus 75 / SD750 is done, CHDK for the SD750 is included in the official source code tree (trunk).

The SD750 version 1.00B, 1.01A, and 1.02A are now supported in the SVN Autobuilds since #562. Use the Downloads page to get the link to the Autobuild page.

As of build #585, there is still problems with the touch sensitive controls wiping out the CHDK menu, but most of the features work. NEEDS MORE EXTENSIVE TESTING!

TPC Development betas

The following builds were made by TPC based on the allbest #90 build from back in April. Since then, PhyrePhox and several other users on the forums have merged the patches into the Autobuild trunk.

Development for the SD750 CHDK is still in beta, but you can download the latest versions here:

Discuss the current port

As of June 2008, a beta CHDK port is available for firmware 1.00b, 1.01a and 1.02a [1]

Development for the other firmware revisions can be monitored in this thread:

http://chdk.setepontos.com/index.php/topic,898.0.html

Note about the different Firmwares

Cameras with the 1.01a firmware can/must use the CHDK version for 1.01b - the autobuild already just copies this, so when you have a 1.01a cam you will find YOUR version in the autobuild. Development is happening in the 1.01b tree, then compiled and just renamed for the 1.01a people.
