hello, chdk fora!
recently, i bought a cheap canon camera on ebay (SD750, firmware 1.02A, running the 'complete' build at the chdk autobuild download, $50 AU for the camera), cheap for one reason: only a ~10 pixel wide column is visible on the screen, the rest being plain white. so, i'm committed to flying blind. i knew this when buying, but all i want to be able to do is to run a script, ie intervalometer and motion detection. now, i've managed (after much trial and error) to get chdk running, i think. via this set of blind button pushing.
start in playback mode. menu, up, func set. (select firmware update)
right, func set. (select ok)
that, i'm reasonably confident about. however, navigating through to the script menu and to load a script is where i'm tripping up. this is what i'm trying at the moment, based on what i understand about the menu system from the main manual.
shutter full press (extends lens, so it's not in playback mode any more)
direct print button (switch to alt mode)
menu button
down x4 (navigate to 'script menu')
func. set. (select script menu)
func. set (select 'load script')
func. set (load the first script in the chdk/scripts folder. i renamed an intervalometer script to be aaaa.bas to ensure it would be first, also the other example scripts have been removed)
(purely guesswork)
menu (exit the menu? i'm not sure)
and press the shutter to start the script.
however, there are a couple of issues, where i've clearly mistaken some part of the process.
-firstly, i can't hear the quiet clicking that is usually heard when the camera takes a shot. so, clearly i've failed at getting the intervalometer to run.
-secondly, no photos that i take after loading chdk appear on the memory card. ie, if i get out of alt mode, and take a shot that i can hear the camera taking, i can't find this in the memory card at all. is saving to the memory card a non-default option that i need to find? otherwise, i'm confused on that one.
so, in general, if someone could find the place(s, most likely) i'm going wrong, that would be great. ultimately, i'd like to join the throng of people putting up a camera into the stratosphere via weather balloon, so i don't need to know the entire menu system, just enough to run a script. many thanks to anyone with time to help out, and, obviously, many more thanks to those who put together this system! scripting alone is an awesome thing to have available on a camera.
