I'm trying to call "return call_event_proc("PTM_GetCurrentItem",ID)" scripts for ID=0x8000..8200, but it returns always -1

When an eventproc returns -1, it usually means that it is not registered. Execute UI.CreatePublic prior to calling the PTM event procedures.

When I tried to call "return call_func_ptr(0xff8a1464,ID)" it returns some values, but camera crashed on the ID=0x80c6.

The number of these UI properties is detected by the sigfinder, see stubs_entry.S:

Code: [Select]

DEF_CONST(uiprop_count ,0x000000c6) // Found @0xff9aeac4Requests for nonexistent properties are usually rewarded with an assert.

I can't give an answer to all those test failures at the moment, but here's a few

3. isobase - reports "set CAM_MARKET_ISO_BASE 200"

CAM_MARKET_ISO_BASE needs to be redefined in platform_camera.h

4. mftest - reports error at mftest.lua:150 - attempt to compare nil with number

This might have to do with the version control (svn is expected)?

edit:
How much free memory does CHDK report (miscellaneous stuff -> show memory info)?

Thank you, works good.

Why not to create standard Lua functions for UI properties, like http://chdk.wikia.com/wiki/CHDK_Scripting_Cross_Reference_Page ?

Probably. I'm using build from adong, and he builds from own git.

Just after switch on: 3121736, CHDK size: 141408 bytes, loaded at: 0x185CB0
After some shoots: 2990320
After next shoots: still 2990320

Hi guys,

I'm looking for a camera to work with CHDK for aerial mapping. I wanted to know if this model (IXUS 160) would work with the porting you are discussing here.

In my opinion: if you need faster shoot rate, this cam is not for you. The official spec is 0.8 shot/sec for continuous shooting, the practical rate will be even slower.

Hy guys,

This is a major milestone for drone aerial photography, as IXUS160/ELPH160 is the first 20MP light weight camera (127g) with CHDK. There are quite a lot of people waiting for this CHDK.

Congrats to you who make these developments work!

Hi all, awesome work for CHDK! I just bought 2 of the ixus160 and I would like to help. I can test, but can also help with coding or scripting. It is my first project for a camera, but have some experience in other fields.

So how far is this port at this time? Where can I start?

See attachment in the http://chdk.setepontos.com/index.php?topic=12321.msg123174#msg123174 message, and use http://zenoshrdlu.com/stick/stick.html for write firmware to SD card.

Thanks to diybookscanner group, now I have access to this camera

Based on adong port, I'm testing and preparing the patch to trunk. When I try to compile it. I got this error:

Code: [Select]

stubs_entry.S:57: Error: bad instruction `def_const(uiprop_count ,0x000000c6)'

If uiprop is defined in stubs_min.S, the port compiles. Any ideas?
I found the same problem trying to port ixus145. Thanks.

If it's defined as 'def_const' (lowercase) in stubs_entry.S it will fail - the macro name is 'DEF_CONST' (uppercase).
