CHDK Specialties
This section describes special CHDK-related things...
This camera set for right/ left/down /up/set /menu Key a bit on keypress.
But for zoom in out, it work as all other Canon Camera and clear a bit on keypress.because of this behavior there need platform kbd.c change.trhis camera seem the only that work in that way.
Also the Video Button can not block from chdk.it execute always original Firmware Code.So it cant use as alt key.so because of no print key its not clear now what use as alt key.I use for test Set button.need add code, so only a press of Set button longer as 0.7 sec switch to alt mode

http://chdk.setepontos.com/index.php?topic=6179.msg63254#msg63254
For 100F best is add this code too, to avoid slowdown or crashes on RAW better
Status 2/2011
ISO overwrite work, when you set 1 of this allowed values.125,160,200,320, 400, 640, 800, 1000, 1250 ,1600 2000,2500
Status 1/2011
Keys now perfect work.Video key is use to switch to alt mode.longer press of video key start video record
Raw with DNG work ok now.This Camera use a diffrent Sensor Pattern
green red
blue green
as all other Canons, so there is no CRW konverter currently here.
RAW DNG savetime is 1.4 - 1.5 sec(series shoot and use new chdk doublebuffer feature) with a sandisk ultra 8 GB 15 Mb/sec(write bench show 12 megabyte, but its only a class 4 Card.).with CRW savetime is 1.2 -1.3 sec, so not very important to have CRW here.
Auto chdk Boot of Camera does work(test on a 4 GB Card only)
scripts do work(also intervalscripts that do shoot), text output of scripts is now too show.problem was
whats currently not working see here

Status 12.2010 ******************************************************************
chdk usable features.
GUI Layout Editor.Battery % Show, Histogramm, DOF Calculation, Super Fine JPG Save Mode, zoom Value.
when you set the 16:9 (wide) shooting mode, Overexpose/underexpose Dot work in Historgramm and Edge Overlay work too.seem chdk do not handle diffrent shooting modes as 4:3 shoot mode on a 16:9 display and 16:9 shoot mode on 16:9 display
alt key Mode work not very good due to problem in alt or normal key mode.when you leave chdk alt mode, you need press this keys(left, right, down, up, menu, set) (you need not press all together) so the firmware can recognize keys again.
in alt mode, do not work to hide keypress from the firmware rom correct.so better avoid to use the alt mode if possible.
The port do no random crash so can use.
whats not working but important.
print show no text in scripts, so can not see if a script correct work or not.
RAW in crw cant open by any program
RAW in dng can not save because badpixel.lua not work correct
raw image with badpixel.bin from SX210 show wrong colors.
Grid overlay is wrong center in 4:3 shoot mode and in 16:9 shoot mode its too small in X
In the 100d Firmware video patches are deactivate
