Wow - first submitted patch in almost six months.  That must be something of a record.

Patch to fix OSD keyboard for Powershot N & Powershot N Facebook when CHDK OSD is rotated 180 deg.

(per http://chdk.setepontos.com/index.php?topic=12684.msg126574#msg126574)

Also removed a bit of dead code just because.  As noted elsewhere,  the touchscreen code for the four or five ported cameras needs to be harmonized at some point.

Added in revision 4425.

Patch to enable the RAW exception for "Sports" mode on the SX50hs per Disable raw in Sports Mode on SX50?

Patch works for both 1.4 and the dev trunks.  Tested on 1.00c firmware.

Patch, check for installed toolset
« Reply #1463 on: 15 / May / 2016, 08:55:12 »
Just starting with some development, and it is annoying for me that I need to set the OPT_USE_GCC_EABI, while it can be detected easily.
Yes, I know that it can be put in buildconf.inc, but I like to minimize the number of necessary settings.

A hint for language ids?
« Reply #1464 on: 15 / May / 2016, 09:00:55 »
Hello,

The default.lua script does not work correct when the user uses another display language as german or english.
While this is not a show stopper, I would like to modify this script, so all languages are supported. But can someone give me a hint where I can find the language numbers for all other languages?

The script reads property case 196 or 61 (depending on the cam's propset). It then tries to work out the correct offset for the recognized languages.

Problem is:
- we don't know the correct propcase number for some propsets (this propcase is not in the propcasex.h headers)
- I'm not sure we know all details about how Canon has been expanding the list of supported languages

I've been thinking about using a different method. There is a firmware function I named "get_string_by_id". For ID=0, I think it returns the name of the currently active interface language as UTF-8(?) string. Problem is,
- this function is not currently identified for early (VxWorks) cameras
- it's not exposed to scripts
- it has only been tested on a few models

Should this discussion continue, it's better in a separate thread.

About auto-recognizing the toolchain: I'm neutral on this. Let reyalp decide.

I don't care much one way or the other about auto-detection, but I think eabi should be the default and should be used for all normal CHDK development now. It's already the default on the autobuild and required for D6, and pre-built toolchains are available for most platforms. We could still use the auto-detect logic.

I'd be tempted to remove elf support either before the 1.5 release or for 1.6.

CAM_MAX_ISO_OVERRIDE
« Reply #1467 on: 03 / June / 2016, 20:21:40 »
Posting this here before commit, so there's a chance someone will notice if there's something obviously wrong with it.
CAM_MAX_ISO_OVERRIDE, introduced specifically for the sx520/530 port which has problems with high ISO values.
I simply searched for CAM_MIN_ISO_OVERRIDE and added the optional upper limit where the lower limit is enforced.

Patch (with slightly different comments) was originally posted here: https://chdk.setepontos.com/index.php?topic=12418.msg128758#msg128758
