Menus and submenus
PostPosted: Tue Mar 13, 2012 6:13 am     Reply with quote
I have a menu with several submenus.
Example:

1.main menu
1.1. submenu
1.1.1.subsubmenu

From main menu i enter submenu1 with an enter button press.The problem is if i hold the button for a while, i enter directly the subsubmenu.
I want when i press the button briefly or hold it to enter only the submenu.When i release the button and make a second press to enter the subsubmenu.
I use a previous button too.
I think i should give to each submenu a unique address and call it when i need it but i don't now how.

Here is my button code for enter and previous buttons.
I use flag_enter_prev_main for the result of enter and previous button presses.

Code:

//these are enter(C3) and previous(C0) buttons
    if(!input(PIN_C3) && status_enter_prev_main==0) //enter button
    {
      flag_prev_main=0;
      flag_enter_main=1;
      status_enter_prev_main=1;
      delay_ms(100);
    }
    if(!input(PIN_C0) && status_enter_prev_main==0) //previous button
    {
      flag_enter_main=0;
      flag_prev_main=1;
      status_enter_prev_main=0;
      delay_ms(100);
    } 
     
    if(input(PIN_C3) && input(PIN_C0))
    {               
      status_enter_prev_main=0;
    }
    flag_enter_prev_main=!flag_prev_main && flag_enter_main;
    //end of enter and previous buttons

Code:
while(!input(PIN_C3)        // Loop here until button released.
{
      delay_ms(50);
}

Add this after your button check code
if(......
