STM CircleOS forum / Meaning of the MENU_codes

Hi,

Even after I read this : http://www.stm32circle.com/circleos_doc … 4a844d6c63
I still don't get the meaning of the various MENU_code and what it does when returned (e.g MENU_CHANGE -> Change to what ??).

I haven't found the file that describes how it's treated.

Please dear Circle, enlight me :-)

Thanks, clemzzz

CircleOS calls your main function loop. Then your main runs, and returns one of the MENU_codes. If it returns MENU_LEAVE that means you want to quit application and CircleOS will not call your main again. If you say MENU_continue, it will call it again.

That makes more sense?

Ok thanks,

Do you know more about the use of MENU_REFRESH and MENU_CHANGE ?

MENU_CHANGE indicates that a new menu has been created, and as its name says, the menu has changed :

Example :
// Check for operator menu request
if ( BUTTON_GetState() == BUTTON_PUSHED )
{
BUTTON_WaitForRelease();
MENU_Set( (tMenu*) &myMenu );
return MENU_CHANGE;
}

MENU_REFRESH forces the system to redraw the current menu, by invoking the function MENU_Set.
Example : function "MsgVersion" in application.c.
