updates to GPS functionality for cameras with built-in GPS rework of CHDK color palette handling to allow separate palette definitions for each camera model - transparent grey color defined for OSD background use enhanced UI functions for touchscreen-equipped cameras - touching menu areas and window buttons directly now works Made Lua script API use of boolean values more consistent, 1.3 provides backward compatible behavior) Added parameter to specify version of CHDK script was written for, 1.3 assumed if none present. Lua scripts now "compile" when loaded to reduce memory needed (original script text no longer stored in memory) script header now supports for better organization in script that use many parameters upper and lower case single characters can now be used as variables in uBASIC
CENON A800 FULL
enhanced script header including compact format, Boolean values, table support, and full variable names in Lua. long file name support in script, file browser / selector.
CENON A800 UPDATE
You must update these when you update your build. Modules and language files are NOT compatible. CHDK 1.2 CFGs should be migrated as was done for 1.3. Custom colors will be reset, and if you switch back to 1.3, colors may be incorrect. It should generally be compatible and retain your settings, but if you don't want to risk re-doing your CFG, backing up the CHDK/*.CFG files before updating is recommended. CFG files: CHDK 1.4 uses the same CFG files as 1.3. This does not affect common modes like, M, P and Auto, but might affect scripts that use more obscure modes, especially if the are referred to by number rather than a names Some CHDK script mode numbers have changed, and some names have been removed. If you use 1.4, the return values of some functions are changed. You will see a warning if is not specified in the script header, but 1.3 compatible behavior will be used.
The best method for doing this depends on how you intend to use your camera and the date your particular camera was released. Once you have the correct CHDK installation file for your camera, you need to prepare and load your camera's SD card with CHDK.
CENON A800 INSTALL
To install CHDK on your Canon P&S camera, you need to know the model number and firmware version of your cameras in order to get the right version of CHDK for your camera CHDK is not a permanent firmware upgrade: you decide how it is loaded (manually or automatically), and you can always quickly remove it. It provides additional functionality beyond that currently provided by the native camera firmware. CHDK gets loaded into your camera's memory upon bootup (either manually or automatically). CHDK (Canon Hack Development Kit) is a firmware enhancement that operates on many Canon Cameras.
