B4R Question Arduino Mega stack problem

[Mostez]

Hello,
I wrote code for arduino mega with 3 menu selections, each menu has 4 items. Each sub routine of them includes this select statement to branch according to keypad press.

private Sub MenuDBfiles(KeyFromMenuHandler As String)
    MenuIndex = MENU_DB_FILES
    If KeyFromMenuHandler = KEY_NONE  Then
        Clear
        PutString(0,0,"UPLOAD DBF",FontArial8x16,True)
        PutString (0,2,"1- Daily",FontArial5x8,False)
        PutString (0,3,"2- Monthly",FontArial5x8,False)
        PutString (0,4,"3- Archive",FontArial5x8,False)
        'PutString (0,5,"#- Cancel",FontArial5x8,False)
    End If
   
    Select KeyFromMenuHandler
        Case "1"
            UploadDailyDBF(KEY_NONE)
        Case "2"
            UploadMonthlyDBF(KEY_NONE)
        Case "3"
            UploadArchive(KEY_NONE)
        Case "#"
            Clear
            MainMenu(KEY_NONE)
            Return
    End Select

End Sub

The problem is before adding this menu part the code ran very well, but now it stops at start up and sometimes with array index error, when i comment some of these routines it runs OK, i tried to expand StackBufferSize to 1000 without any success!

is there a solution for this nesting or stacking problem?

NOTE: the code consumed 25% of code space and 50% of memory space
Thanks

Can you upload the project?

 

[Mostez]

OK, attached

It sounds like a memory issue.

Does it work properly if you make the font arrays much smaller (remove most of the characters and try it)?

If so then you can move the whole arrays to the program code instead of the RAM: https://www.b4x.com/android/forum/threads/using-progmem-to-save-memory.71114/#content

i did not try it yet, i will try it and let you know. the strange thing is, it is 50% of memory space, and the program runs abnormal

yes Erel, it worked perfectly, reduced from 61% to 37%

I don't know really how to thank you.. thanks so much
