Can you check if the MENU button works correctly in <ALT> mode?
Pressing the MENU button in alt mode must open the main chdk menu.
The WIFI button also needs to be checked, you can do this by selecting the WIFI button as the <ALT> button.
You should also check ModeMap, just like you did for the sx430.
Go to:
Miscellaneous Stuff -> Debug Parameters
set "Debug data display" to [Props] and "Propcase / Param data page" to [5]
In this case, look at propcase 55.
This is currently used modemap.

//TODO
const CapturemodeMap modemap[] = {
    { MODE_AUTO,                32768 },
    { MODE_P,                   32773 },
    { MODE_LONG_SHUTTER,        32775 },    
    { MODE_PORTRAIT,            32790 },
    { MODE_FIREWORK,            32800 },    
    { MODE_LOWLIGHT,            32813 },
    { MODE_SUPER_VIVID,         33330 },
    { MODE_POSTER_EFFECT,       33331 },
    { MODE_FACE_SELF_TIMER,     33332 },
    { MODE_FISHEYE,             33335 },
    { MODE_MINIATURE,           33336 },
    { MODE_TOY_CAMERA,          33339 },
    { MODE_MONOCHROME,          33343 }, 
};

There are 6 more shooting modes missing. You need to find them if you can.

ntstatic

Here are the mode values

{ MODE_AUTO, 32768 }, OK
{ MODE_P, 32773 }, OK
{ MODE_LONG_SHUTTER, 32775 },OK
{ MODE_PORTRAIT, 32790 },OK

{ MODE_HIGH_SPEED_BURST 32778},OK
{ MODE_HANDHELD_NIGHTSCENE 33337},OK

ntstatic

by the way ... wifi button works ok as the CHDK ALT button

ntstatic

Preliminary testing with PTP .... looks ok
selecting
MODE_FACE_SELF_TIMER actually gives MODE_SMART_SHUTTER in PTP mode

in PTP mode the following buttons checked
UP, DOWN, LEFT, RIGHT
set
menu
zoom+, zoom-
shoot Half, Video
Shoot
rec, play

all work as intended

JPG remote shoot gives ERROR: unsupported format
DNG remote shoot works ok

Raw looks ok (just did a quick look using RawTharapee)

Okay, just try the mftest.lua script and upload a dng file to measure the active area of the sensor.
This time everything was done very quickly. 😁

Indeed it was very quck 😀

here are the raw and associated JPG on google drive

the CSV file from the test is also attached

on further checking
using PTP

ExecuteScript("set_tv96(" & mTVval & ") sleep(100) set_user_tv96(" & mTVval & ") press 'shoot_half'")
setting Exposure works ok

ExecuteScript("set_sv96(" & mISOval & ") sleep(100) set_user_sv96(" & mISOval & ") press 'shoot_half'")
setting ISO works ok

setting manual focus - after AFLock - works ok

however

ExecuteScript("set_av96(" & mAVval & ") sleep(100) set_user_av96(" & mAVval & ") press 'shoot_half'")
setting Aperture has no effect

ExecuteScript("set_av96(" & mAVval & ") sleep(100) set_user_av96(" & mAVval & ") press 'shoot_half'")
setting Aperture has no effect

The camera has no iris, it has only ND filter.

If you do not have any objection on the functioning of this port, I will make a patch today to add the source code to the trunk.

the port seems fine, in fact behaves very well. it is definitely worth adding to the source

thank you, you have ported two of the currently available cameras ( sx430 and ixus285 ) .... that is something that has been missing from CHDK for a long time

Thanks for posting this, added in trunk 5142. The forum should be accepting patch files again.

I haven't looked at the code closely, but a few comments / things @nstatic could check

NUM_FL detected by the sig_finder is 551, which seems like a lot, especially for a camera that isn't a super-zoom. You can check:
1) The focal length display in misc values looks reasonable at min, max and some in between zoom levels (use FL or EFL).
2) If you manually zoom to max, is the get_zoom() value something like 550 or 551?

CAM_IS_VID_REC_WORKS is not defined. This should only need movie_status (which is found by the sig finder) not a full movie task implementation, so it should be tested. You can use vidtest.lua in the TEST directory.

Are the CAM_SD_OVER_IN_* defines tested?

The code to detect playback / power button long press startup in boot.c (top of sub_FF0203C4_my) as a TODO on it. The expected behavior is
* short press of play or power button starts in play
* longer press of power starts in rec
If the camera starts in rec from a short press of play, this should be fixed.

Some modemap entries detected by the sigfinder are in the CHDK list. Sometimes these are accessed from a the menu, or different options in a scene mode.

Sorry about the late reply, I was away from home.

It seems right, given the mf_ixus285_elph360hs.csv attached a few posts ago.

The code to detect playback / power button long press startup in boot.c (top of sub_FF0203C4_my) as a TODO on it. The expected behavior is
* short press of play or power button starts in play
* longer press of power starts in rec
If the camera starts in rec from a short press of play, this should be fixed.

This should definitely check,maybe the camera starts with screen for wifi settings, if the camera can be turned on with wifi button.
