Hello, thanks for making CHDK available for the Powershot A530. I'm new to this so I need help with some questions.

I've downloaded the CHDK 0.5 beta build+source: a530-trunk-334.zip - 0.23MB file and unzipped it.

In the a530-trunk-334 main folder,  there are 3 sub-folders (bin, loader, platform).

The bin folder contains the usual diskboot.bin and ps.fir files.

What are the loader and platform sub folders for? Do I need to save these onto the SD card to activate the <ALT> mode functions?

Also, how do I activate the camera to save images as a RAW file? Pressing the DirectPrint button gives me no results and does not activate the <ALT> mode. (I've tried this without saving the loader and platform sub folders onto my SD card yet).

Some assistance would be apreciated.

These are sources for developers.

hi,

best is to read the chdk fqa at

  http://chdk.wikia.com/wiki/FAQ

about how to get chdk onto your camera - also you should
check if you have the firmware version 1.00a (how is also
described in the faq) ... then (after the whole procedure) you
should definitely get an alt menu from the print button

best wishes and good luck - image13

just fyi: the a530 port is now in the trunk, i.e. you
should be able to find the latest fresh binaries as
part of grands great new autobuild at

  http://grandag.nm.ru/hdk/autobuild/

a lot of thanks to bondo, grand and all the
others who made this possible

During surfing through the CHDK menus I somehow triggered 30fps display in the video mode.  :o The picture displayed "smoothly", but I wasn't able to record anything. The record started, but, when I pressed the button, nothing was saved and the camera turned itself off... I do not remember what I did. I'm only sure that I didn't change any options aside from switching the "optical zoom" option in CHDK video settings on and off.

I hope this information helps in some way. :)

Best regards,

M. R.

Hmm, A530 (and A540) do not support optical zoom in video (because have been added to trunk recently).

edit: Now this support added.

Try to use this script :this is not my script:)

rem  author  Divalent.  Modification of Fingalo's sample script
rem  this only works with Fingalo's CHDK build
@title propcase
@param a propid
@default a 30
@param b set value
@default b 0

rem  variable "c" will be the actual value reported
rem  b = what you will set it to
rem  a = the property you want to detect and/or change
rem d = variable "delta" amount (can be 1, 10, 50, or 100)

d=1

:loop
rem print current state of property

  get_prop a c
  print "P",a, "=", c,"set2=", b
  print "delta=", d, "(Z-in alters)"
  print "[set]= set prop to set2"
  print "L/R/up/Dn alter P or set2"
  print "[menu]= shoot and exit"

  wait_click

  is_key k "zoom_in"
    if k=1 then d=d+9
    if d=19 then d=50
    if d=59 then d=96
    if d=105 then d=100
    if d=109 then d=1


  is_key k "up"
    if k=1 then b=b+d
  is_key k "down"
    if k=1 then b=b-d
  is_key k "left"
    if k=1 then a=a-d
  is_key k "right"
    if k=1 then a=a+d
  is_key k "set"

  if k=1 then set_prop a b


  is_key k "menu"
    if k=1 then shoot
    if k=1 then sleep 1000
    if k=1 then goto "lend"


goto "loop"

:lend

end
------------
and  set propcase
:126 to 30 or 60
:127 to 2
128 to 1
 , in my camera that works and i could record in 640res with 30fps

This is exactly the script I've been playing with for some time now... :) When I set 126 to 30, or 60fps, almost nothing changes. Videos are still recorded in 10fps. The only visible thing is that, if the value is set to 30, a 30fps (instead of 10fps) icon is displayed on camera's OSD when playing the video.

:(

:)

M. R

Here's a pic of my A530's display. (I took it using my old Nikon Coolpix 775 :)) It shows the properties of a clip recorded in "30fps". I recorded it after I had changed the 126 value to 30 using the 'property case value" script. However, the clip is "de facto" in 10fps. It would be interesting to find out how the camera "promotes" the video to 30fps.

:)

Best regards,

M. R.

Hello,
 Also thanks from me for making CHDK available for the Powershot A530. I have it running and will read the instructions and test it out. Great Work.
