OSD captures

PanoWorksAdded by PanoWorks
Various modes have specific OSD elements.

In PASM modes, most likely to be used by CHDK users, there are some common OSD elements shown in the image here.  Note that most of the elements lay on an outer 'ring' which may interfere with CHDK OSD element display.  The date/time stamp, digital zoom and GPS options lay a bit inside, but the former two are also likely not used by CHDK users.

One particularly different OSD display is used with the Stitch Assist mode, as the actual view is reduced.

Shown is Stitch Assist with panning to the right - panning to the left has the inner display box mirrored.

CHDK Specialties

This section describes special CHDK-related things...

Known issues

  • CHDK RAW (and also DNG) files are not created correctly when the camera is in AUTO mode; if you want to store RAW or DNG images, use the camera's M mode. Fe50 (talk) 20:39, December 25, 2012 (UTC)

Shortcuts

  • To get into the CHDK menu while in camera mode, press the playback button
  • To enter playback mode, press and hold the playback button

File System Support

  • When using the firmware update method to load CHDK, the storage can be formatted as exFAT and CHDK will be able to write images to it.  Video recording to exFAT using CHDK has not been tested.

LED addresses

  • First, enable control by writing 0x46 to the following addresses:
0xC022C200 <-- Required for AF Beam control to work
0xC0223000 <-- Required for I/O LED control to work
0xC0223070 <-- Required for I/O LED control to work
  • after doing this, these are the on/off addresses:
0xC0223030 <-- AF Beam
0xC022C028 <-- I/O LED
  • Write 0x46 to light the LED, 0xCF to turn it off.
  • Writing 0x44 will turn off the AF beam, but it won't turn off the I/O LED. 0xCF works for both.
