It doesn't look good.
I guess <means slow speed and << means full speed
Can you repeat the slow speed?
Stay in play mode and then

1. execute rmem -i32 0x1469c 3 without pressing any keys, repeat it twice and post both results

2. move the zoom lever and keep at a slow speed and execute rmem -i32 0x1469c 3

This time do not check full speed, to avoid confusion.

When looking for bits in physw_status, a debug display showing individual bits can be useful, if you understand how to use it. Read the instructions and follow them before re-compiling.

69 is changing with the language, 65537 is English, 66305=German, 70913 Italian, 67329 Spain, 67073 France, 68609 Dansk, 69377 Portugues, 70145 Suomi, 71169 Magyar, 69633 Polski, 70401 Cestina, 66817 Türkce, 66049 Romana, 65793 Norsk, 66561 Svenska,
68865 is Russian, if I understood the regulary lessons right...

This is quite strange.

From what we've seen before, the low byte of the language prop NTSC (=0) or PAL (1) and the high byte is language, in the range 0 to ~20, with English = 0 and the rest going by row or column depending on propset.

In your values, it matches propset 10 or 12, but the high bit of the language byte seems to be set. Ignoring this bit, the values look like propset 10 and 12.

It's possible some other setting is stored in that bit, it would be nice to know what if it is. I would guess it would be something language / local related.

Anyway, I've updated default.lua in trunk r5964.

Tried to record twilightzone with an Ubasic script:

Code: [Select]

@title peek 0x1469c
@param s 0x1469c & s
@range s 1 16
@default s 1

pri.-11
s--

?=*:=?:=/:=%#0;,=%peek 0x1469c,4:

10 p=peek 0x1469c,4
 if p!=#0 && p!=P then print gtc%1000,=%p, =%p^#0 ~P=p
if odd s then ?=%(p&(1<<s))
 P=p
goto -10

:restore
?=%peek 0x1469c,4,=%#0
end

As a trailer the first sec in rec & play with relaxed zoom...

Thanks, it shows this:
{ 0, KEY_ZOOM_IN ,0x00000200 }, // Found @0xff5ba424, levent 0x03
{ 0, KEY_ZOOM_OUT ,0x00000400 }, // Found @0xff5ba42c, levent 0x04
If it's a really slow zoom speed, then if you have the camera in rec mode and the chdk <ALT> is active, when you push the zoom lever all the way, the lens should start moving.
Can you check that?

After booting to CHDK-rec zoom is moving, was irritated by the <ALT>...
Edit: Same moves when pressing 1/2 zoom...

I don't understand, zoom doesn't work in <ALT> mode?

When the CHDK Gui (Bat, clock) is active, it works. If the <ALT> Icon is displayed, and shoot starts script, it doesn´t. When it does, half or full press doesn´t matter.
Running a script using zoomkeys is fine, too.

@Caefix
OK, that's expected behavior.
When you see the <ALT> icon on the display the camera is in the so-called alt mode, then the keys must not respond in the usual way.
If you open the chdk menu and for example try to set "Override ISO", you can move the cursor with the zoom buttons. Outside of alt mode the zoom buttons must move the lens in rec mode or enlarge or reduce the displayed image in play mode.
EDIT: One position of the zoom lever could then move the lens, regardless of the alt mode. I assume the known values (ZOOM_IN 0x200 and ZOOM_OUT 0x400) are for full speed.

If you haven't lost interest you can see what happens when you move the zoom lever at 0x146a0, using a memory browser.
