How to make menu settings persistent?

Hi,

I finally found some time to do some further investigations in CHDK development.
Today I wanted to try to create an additional menu inside CHDK Settings-->Remote Parameters.
I already could making a submenu with two subitems (of type MENUITEM_BOOL) working.
I can see and toggle the subitems using the 'set' button of my camera.
But if I switch off the camera and on again these values are always enabled.
So for some reason my settings are not persistent.

What I did:
1. Added the menu and two submenus in gui.c:
Code: [Select]

static CMenuItem test_submenu_items[] = {
   MENU_ITEM   (0x2c, LANG_MENU_TEST1_ENABLE, MENUITEM_BOOL,     &conf.test1_enable, 0),
   MENU_ITEM   (0x2c, LANG_MENU_TEST2_ENABLE, MENUITEM_BOOL,     &conf.test2_enable, 0),
   MENU_ITEM   (0x51, LANG_MENU_BACK,                    MENUITEM_UP,       0, 0),
   {0}
};

static CMenu test_submenu = {0x86, LANG_MENU_TEST_TITLE, test_submenu_items };
2. Added the two int values to struct 'Conf' inside conf.h
3. Added following to conf.c:
Code: [Select]
   
    CONF_INFO(300, conf.test1_enable,             CONF_DEF_VALUE, i:0),
    CONF_INFO(301, conf.test2_enable,             CONF_DEF_VALUE, i:0),
4. Appended values to gui_lang.h and english.lng for the menuitems text

I see inside conf.c that there are functions config_save and save_config_file. But it seems that they don't care for my additional menuitems.
I also found out that the seetings are stored in CCHDK4.CFG. I used the Java tool chdkcfg.jar (from I think Dave Mitchell? -->Thanks :-)) to make these values readable, but my values are not in that file.

May someone from the experienced guys here can tell me how to make my values persistent?

Thanks a lot...

It's been a long time since I added a conf entry, I don't see anything obviously missing in your description.

Possibly a silly question, but are you exiting the CHDK menu or alt before turning the camera off? Those are the points when the conf file is actually saved.

    CONF_INFO(301, conf.test2_enable,             CONF_DEF_VALUE, i:0),


Did you add these before the '{0,0,0,0{0})' entry that terminates list?
If you added them after they will be ignored.

Hi reyalp and philmoz,


the 'silly question' did the trick ;-)

I did not press 'alt' or 'menu' I just switched off the camera so no data have been saved.


Problem solved - thanks!
