where do i find a list of property values for the sx30is and a495s, i'm trying to write a script to work on both and after 5 hours i'm off to bed lol

all i have had is crashes and locks because i'm obviously not reading/writing the right values to the right places...

You might also find that your SX30 has many propcas attributes similar to the SX20. Here are the ones I've tested on my SX20: http://chdk.setepontos.com/index.php?topic=4348.msg60704#msg60704 Note: Although all are "read" capable, not all may be "write" capable.

If you write your scripts in Lua, you can use use the propcase module and refer to know propcases by name. See http://chdk.wikia.com/wiki/Lua/Lua_Reference#get_prop

The names/values are taken from LUALIB/GEN/popcaseN.lua

You shouldn't use these GEN files directly, but they may be a useful reference if you want to update the wiki.

I have been collecting quite a few of them today, i think i have the zoom/focus/aperture/ shutter/display/iso and mode knob right, from that I should be able to write what i started, I dont know about editing the info in the wiki's and suchlike but once i have tested these values work (next free day saturday) as some of them seem duplicated i'll just post the list.

I believe all of these should all be identified in propcase.lua already. If not, the ports are broken, and more needs to be corrected than just the wiki. Note that in some cases there are multiple props which refer to (mostly) equivalent values, so you might have found a different value than the one listed.

You can look here:
a495 http://trac.assembla.com/chdk/browser/trunk/include/propset3.h
sx30 http://trac.assembla.com/chdk/browser/trunk/include/propset4.h

If you want to update the wiki to reflect the propsetN.h values, that would certainly be welcome

The wiki should probably link to the propsetN.h headers for each propset.
