Is there scripts for Av priority? I'm also interested in manual focus, possible? Thanks.
There are many such scripts - use the search function here and in the wiki http://chdk.wikia.com/wiki/CHDK to find one that meets your needs.

On my port [101c] there is not an 'Override Aperture' option in the 'Extra Photo Operations' menu.

If I recall, there may not be a option for Av Priority [aperture] in this type of camera. If I'm not mistaken that is due to the fact that the camera doesn't have a 'proper' aperture mechanism – I think it is something to do with ND filters being used. But don't quote me on that. I'm still learning this chdk thing as I go.

Update: From the chdk manual explaining a little more about the aperture override.
http://chdk.wikia.com/wiki/CHDK_User_Manual#Override_Aperture

can't find" Override Aperture"

Correct.  In fact, the platform_camera.h file for the IXUS220HS, which tells the CHDK build process how your camera is configured,  has a line that says :
#undef CAM_HAS_IRIS_DIAPHRAGM
which means CHDK is compiled assuming it cannot control an aperature mechanism.

You are probably going to learn a lot more about CHDK by reading the links I posted for you on Dec 26th and by searching for things yourself rather than posting each question 1 by 1 here on the forum.  Here's one last hint :

Hi everyone.
Even I’m a newbie to CHDK, I got good results for the remote control of shutter and zoom of my IXUS890IS on a KAP cradle with the suitable CHDK and a script based on USB power pulse width, like those described here (http://www.zenoshrdlu.com/kapstuff/zchdk2.html)
To reduce the weight of the aerial platform, I got the IXUS220HS /ELPH300 as the suitable CHDK build (1.0.1 e) was released a few weeks ago.  Unfortunately, up to now, I could not get any control of shutter or zoom with USB power pulses  (shooting is OK via scripts). The green led above “Disp” button lights and a very low bip can be heard when sending the pulse without any further action. Does anybody know of the capability of the IXUS 220HS/ELPH 300 for CHDK USB remote control ?
Thanks in advance.

I tried Override Subject Distance but for me doesn't work. I'm asking if there's another way to focus manually, with a script for example. thanks.

- Enter Canon's Focus Lock mode (half press shutter + left)
- Enter Alt mode
- Press Up to enter MF mode
- Use the zoom lever to adjust subject distance (ie, to focus)
- Use Up and Down buttons to change the Factor

There is really only one thing that has to be done correctly in each port in order for USB remote functionality to work.    The value of USB_MASK has to get set correctly in platform/camera/kbd.c  ( and if its not in the third key register, that code has to get tweaked). 

Here's a quick test script to see if that's working.  Run it in playback mode without USB remote enabled.  If you don't have a USB switch,  just plug and unplug any USB cable with the right connectors between your camera and you PC's USB port.

Code: [Select]
@title USB Test

:loop1
  print "waiting for USB"
:loop2
  wait_click 1
  is_key k "remote"
  if k<>1 then goto "loop2"
  print "USB power active"
 :loop3
  wait_click 1
  is_key k "remote"
  if k=1 then goto "loop3"
   print "USB power removed"
goto "loop1"

end

link> Determining the firmware version in your camera.


I'm Sorry ...
