Const struct
PostPosted: Thu May 26, 2016 11:12 am     Reply with quote

Hi all

I use this kind of code with older CCS compiler (<5.50) without any issue.
But with latest version 5.59 I get no error but the code is not working any more.

I point out the default at this point
Quote:
const struct TypeMenu MenuTest[ALL_MENU]

The const struct is not working just struct is working with the last version of ccs.
Is this a compiler error or did I miss something?
Code:

#include <18f46k20.h>
#use delay(clock=16000000)
#fuses INTRC_IO, NOWDT, PUT, NOPROTECT, NOBROWNOUT
#use fast_io(c)
#use fast_io(d)

#include "HDM64GS12.C"   // driver GLCD
#include "GRAPHICS.C"   // graphics

stuff like this is silly oddly-coded.

Code:

case DOWN: 
case CANCEL:

///..

that the argument driving the decisions is a pin number designator
is pretty unusual.

but the code is not working any more.

What did your code do when it was working correctly, and what is it doing now ?

Example:
"My program used to scroll through the menu when the up/down keys
were pressed. But now it only shows the first menu. The up/down keys
do not cause it to scroll".

or

"My program used to display the menu text. Now it displays garbage".
(Then post the text that it should display, and post the garbage text that
it now displays).

Give us a detailed explanation of how it's failing. Tell us what you see.

on a simple menu like on the example

My program used to scroll through the menu when the up/down keys
were pressed. But now it only shows the first menu. The up/down keys
do not cause it to scroll. It stays stuck at the first menu position. The first position menu is working when I press enter (clear screen and go back to menu after delay)

In more complicated menu key do not scroll and text is garbage.
working : Menu
default : ꟻꟻꟻꟻꟻꟻꟻꟻꟻꟻꟻꟻꟻꟻ

When I only declare
Quote:
struct TypeMenu MenuTest[ALL_MENU]
instead of
Quote:
const struct TypeMenu MenuTest[ALL_MENU]
it work but only with small menu. with big menu I get not enough ram size.

this..
with big menu I get not enough ram size.
.. should be a clue.
Look at the end of the listing and see what resources are used
ROM%

RAM%

STACK.

'not enough RAM' means there isn't enough RAM to run your program !
The fact you're using a GLCD means you probably ave a HUGE mount of RAM given to the driver's db of 'fonts'. This is not shown in the program you've given us.
Since your 'memu' system/functions worked before, simply go back xx versions, and see what you've done since then. THAT is probably why 'it doesn't work'.

Hi Jay

I made no change, if a build a version with 5.50 it works if a build a version 5.59 it doesn't.

OK, I copied your program, remarked out the GLCD code and it compiles fine, NO errors. Uses 2% ROM, 3-4% RAM.
One glaring issue I just saw is that you have the interrupts enabled with NO ISRs ! That is very, very bad and will lead to unpredictable problems like crashes, 'funny' results, etc.

Hi Jay

Your right living the interrupt enable is not a good idea for my sample prog but it's not the cause of the problem I get.
As I told you I have no build error so I suppose it's a buggy version of CCS

It is a bug. I finally had time to investigate this thoroughly. There is
a problem with copying an array element from one array to another
when the source is a structure declared as 'const'. There are a few lines
of generated ASM code that are incorrect, starting with compiler vs. 5.057.
I did a complete write-up of the bug and sent it to CCS just now.

CCS quickly emailed me a new PCH.DLL file. I used it to replace the one
in the DLL\5.059\ subdirectory in the CCS folder. It fixed the problem.
When I ran the test program shown below in MPLAB vs. 8.92 simulator
it displayed the following results in the Output Window. This is the correct output:
Quote:

> Menu1
> Menu2
> Menu2 sub1
> Menu2 sub2

Test program:
Code:
#include <18F46K20.h>
#fuses INTRC_IO, NOWDT, PUT, NOPROTECT, NOBROWNOUT
#use delay(clock=16M)
#use rs232(baud=9600, UART1, ERRORS)

#define ALL_MENU  4

enum ids{   _BEGIN,
            _MAIN,
            _MAIN1,
            _MAIN11,
            _MAIN12
        };
       
struct TypeMenu {
             int8 MenuID;
             int8 SubMenu;
             char MenuName[18];
            };
 
//-------------------------------------------
const struct TypeMenu MenuTest[ALL_MENU]
   ={
        {_MAIN, _BEGIN,"Menu1"},
        {_MAIN1,_BEGIN,"Menu2"},
        {_MAIN11,_MAIN1,"Menu2 sub1"},
        {_MAIN12,_MAIN1,"Menu2 sub2"}
   };

struct TypeMenu MenuPointer[2];


//==================================
void main()
{
int8 i;
int8 k;

k = 0;

for(i = 0; i < ALL_MENU; i++)
   {
    MenuPointer[k] =  MenuTest[i];
    printf("> %s \r", MenuPointer[0].MenuName); 
   }

while(TRUE);
}

After installing the new PCH.DLL file, the compiler reports its version as
5.060. If you need this DLL file, contact CCS (if you own the compiler)
or wait for vs. 5.060 to be released.

Hi in_nursery

I'm still facing the same problem as yours. With latest CCS Compiler version this menu code doesn't work! Were you able to found a solution for this other than compile the code with 5.50?

Thanks
Hugo

I don't think you have the same problem.

The fix, is there in 5.061, 5.062, and 5.064 (just tested all of them, and they run fine).
