Ixus275/Elph350 HS porting thread

Here is the initial source code for the Ixus275_Elph350 camera,firmware 100a.
I do not have a camera, so it's worth noting that nothing has been tested.
Any use is at your own risk.

The obvious disadvantages are:
-propset has not been checked
-modemap should be checked
-the WiFi(Connect) key is not in the keymap
-probably needed extra hack for kbd.c, similar to the ixus 175
For further work is needed the help of someone who has a camera with firmware 100a, if the CHDK can be load correctly and if the display is functional.

EDIT: outdated source code removed

I hope the recommended propset 10 is O.K.
Can you try ndtest.lua with this build ?
You should go through these tests:

:( now ndtest crashes with new romlog...
(The former build hanged with blinking cam down-left. get_propset returned 7.)
get_propset returns 10 now.
Ubtest crashed with UBromlog, && other logs.
Edit: Ub-crash fixed with ND issue.

 ::) Great first day, will be back on monday, continuing offline tests...

I found a problem with nd_semaphore, hope that was the only problem.
New test build.

 :haha port needs CAM_ND_SET_AV_VALUE for quick.

 ;) get_zoom_steps should be 101.
maybe main.c (Ixus170, same lens) :
Code: [Select]
// same number of zoom steps as in ixus160
#define NUM_FL      101
#define NUM_DATA    2

extern int focus_len_table[NUM_FL*NUM_DATA];

// Conversion factor lens FL --> 35mm equiv
// lens      35mm     CF
// ----      ----     --
//  4.5       25      (25/4.5) * 18 = 100  (min FL)
// 54        300      (300/54) * 18 = 100  (max FL)
#define CF_EFL      100
#define CF_EFL_DIV  18
(& I would prefere Wifi as alt_key.)
raw & video seem good. (Not tested all modes yet)
Edit: "set CAM_MARKET_ISO_BASE=200"

Edit2: US-B-remote & sync fine.
 ??? Who feels good for ptp tests? I´m troubled by W-X :o & US-A.
