Any feedback is welcome!

Camera depending notes:

- The version for fw 100b is an pre-alpha version, it has not been tested at all, be the first!

This built is based on the port of the A3000 (boot, capt_seq, loader) and the port of the A490 (movie_rec, keyboard routines)

History of changes

Thanks for that update casrap, it seems to have done the trick.

I should get a chance to run some of the test scripts on my A3150 Build 100d later today, but I can now load up the menus.

First impressions are that it is stable on the A3150, I ran setmode.lua, which fails on one test (Set mode P) log is attached.

Lua Lib tests pass. (LLIBTST.LUA)
RomLog dumper works (and rather worryingly there was a romlog to dump, but its from 2010, so no worries there)
drawtest.lua works (colours are a little odd, but we can blame Canon for that  :blink:).
hdr script works
motion detection script works
inervalometer works.
DNG Raw shooting works, badpixel creation works. File is readable in RawTherapee, looks *very* good  :D

According to the firmware the mode maps are the same for the a3100 and the a3150. On the a3100 the test passes. Can you try again with parameter 'mode change delay' set to 3000?

<edit> or turn the flash off in P mode, i think that is causing the fail (charging the flash takes a lot of time).
<edit2> but then you will get an error on another mode that uses the flash.
You can also try to start the script from record mode while P is selected.

About the odd colors; if you go to the Alt menu->chdk settings->color settings->draw palette you can see what colors are available. While in record mode they look nice (be it without any red), but in play mode they are terrible (no red and no blue). The default selection is at least readable in both modes, but not very pleasant to look at.
It will not be easy to find a better color selection for both modes :(

You will probably want to implement the customized palette code for this camera. 

Grep for #define CAM_LOAD_CUSTOM_COLORS 1  (the A1200 implements it for example).

OK, switching off the flash did the trick. Test passes. Thanks.

Already working on better colors, but the cam misses the palette functions that are present in newer cameras.

Great, thanks for the test. It seems the cameras are identical.

I thought they had to be pretty similar since they have the same P-ID, hence my earlier comment "Note: the Powershot A3150 IS has the same P-ID (31f1) as the A3100 IS, ... " when I dumped the ROM.  (http://chdk.wikia.com/wiki/A3100IS)

Looks like a bit of re-badging by the Canon marketing team.

I have attached a rather boring HDR image taken using this A3150 ver 1.00D just to prove it all works.  :D
