I can zoom in and out in 6 steps, shoot a photo and record a HD video by
using commands through the datalink.
The only thing needed is a level converter from 3.3v to 5 - 5.5v with
the use of a mosfet or a transistor.
I had a problem with the camera freezing (CHDK software) during
operation but i found the problem and now everything is very reliable,
the only drawback is the camera's battery which i think will be replaced
with an external one.
The same camera serves me as an airborne fpv camera so it can do
everything i need.
Let me know if someone wants the module code and chdk script.

Dear Chris
I am very interested in getting a copy of the CHDK script and module code.
I have made some basic CHDK modifications to an ixus 80IS which is a simple camera in terms of lens control.
But in real terms have relied on a modified PIC Micro emulating the remote control for the pentax optio s12 together with the paparazzi
led camera control module with a tiny 2.11.
