When the file is showing, you can scroll downwards with the
RIGHT
button, the
DOWN
button, and the
ZOOM_IN
button. You can scroll up-
wards with the
LEFT
button, the
UP
button, and the
ZOOM_OUT
button.
The
MENU
button leads back to the
Text File Reader
submenu:
f
Here, the function
Select RBF Font
opens the font browser (section
4.2.2). A larger font may be easier to read, but it also reduces the amount
of text that can be displayed on one page. Not all fonts support all na-
tional characters. So, if national characters (umlauts and the like) don’t
display correctly, you may want to try another font.
f
The
Codepage
option allows selecting between
Win1251
and
DOS
code-
pages. If a text file does not display correctly and shows strange charac-
ters, you might want to try the other codepage.
f
The reader always wraps lines that are too long to display into the next
line. When the option
Wrap by Words
is set, it will try not to wrap within
words but to honor word boundaries.
f
Finally, the
Enable Autoscroll
option can make the reader scroll auto-
matically. Every time the specified
Delay
expires, the reader scrolls down
one page.
4.10.3 Getting information about the camera
Under
ALT
>
MENU
>
Miscellaneous Stuff
there are a few useful functions
that display information about the camera:
f
Show build info
. Shows the current version of the CHDK in use and re-
lated information.
f
Show memory info
. Displays free memory available in the camera RAM
and the space used by the CHDK.
More information is found in the
Debug
submenu. Most of this informa-
tion supports CHDK developers, but some of it may be useful for “normal”
users.
Warning:
Before playing around with the options of this submenu,
make a backup of your memory card—and in particular, a backup of the
CHDK configuration file
CHDK/CCHDK.CFG
. Entering bad values can cause
the CHDK to fail at start-up. In this case, you must be able to restore the
configuration file from an earlier version (section A.2).
f
Debug Data display
. This can be used for displaying
Property Cases
(sec-
tion 5.6), parameters, and operating system tasks (only when running
under
VxWorks
) on the OSD. Because there are many of these values,
the display can be positioned to a section within the values by setting
the entries
PropCasePage
and
Task List
start
to appropriate values.
