int1 arrays USED to work [SOLVED] - programmer error
PostPosted: Thu Jul 26, 2012 4:31 pm     Reply with quote
this code worked properly back with 4.085 and a few versions after but......

Code:

int1
skipmeK[96]={1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1
,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,
1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1};

// This function WORKS in 4.085 - my old baseline compiler for 18f4525
// but FAILS in 4.135 as follows:
// the bits in skipmek STAY ='1 no matter what
// call with t<12 for EZ check

// called with 'prx'=1 SHOULD set 't' bit to 0 
// the 0-12 test printer is to make it EZ to understand what is going bad

void setskipK (int1 prx , unsigned int8 t){
      unsigned int8 q;
            if (prx)  skipmek[t]=0;   // inverts prx
            else      skipmek[t]=1;
            printf("InDeX %u :",t);
         for (q=0; q<12; q++){
            if (skipmek[q]) printf("1,");
            else  printf("0,");
         }
     printf("\r\n");
}

I made a test program and compiled it with vs. 4.135 and ran it in MPLAB
vs. 8.86 simulator and got this:
Quote:

InDeX 0 :0,1,1,1,1,1,1,1,1,1,1,1,
InDeX 1 :0,0,1,1,1,1,1,1,1,1,1,1,
InDeX 2 :0,0,0,1,1,1,1,1,1,1,1,1,
InDeX 3 :0,0,0,0,1,1,1,1,1,1,1,1,
InDeX 4 :0,0,0,0,0,1,1,1,1,1,1,1,
InDeX 5 :0,0,0,0,0,0,1,1,1,1,1,1,
InDeX 6 :0,0,0,0,0,0,0,1,1,1,1,1,
InDeX 7 :0,0,0,0,0,0,0,0,1,1,1,1,
InDeX 8 :0,0,0,0,0,0,0,0,0,1,1,1,
InDeX 9 :0,0,0,0,0,0,0,0,0,0,1,1,
InDeX 10 :0,0,0,0,0,0,0,0,0,0,0,1,
InDeX 11 :0,0,0,0,0,0,0,0,0,0,0,0,

Is that correct ? The zeros are cumulative because I don't re-initialize
the array elements each pass through the for() loop. But they are being
set to 0.

Here is the test program:
Code:

#include <18F452.h>
#fuses XT,NOWDT,PUT,BROWNOUT,NOLVP
#use delay(clock=4M)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7, ERRORS)

int1
skipmeK[96]={1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1
,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,
1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1};


void setskipK (int1 prx , unsigned int8 t) {
      unsigned int8 q;
            if (prx)  skipmek[t]=0;   // inverts prx
            else      skipmek[t]=1;
            printf("InDeX %u :",t);
         for (q=0; q<12; q++){
            if (skipmek[q]) printf("1,");
            else  printf("0,");
         }
     printf("\r\n");
}

//======================================
void main(void)
{
int8 t;

for(t=0; t<12; t++)
    setskipK(1, t);

while(1);
}

As a comment, why not just use:

skipmek[t]=!prx;

There have definately been some oddities with int1 and arrays. However simple one dimensional arrays do seem to be OK.

I tried it as:
Code:

#include <18F452.h>
#fuses XT,NOWDT,PUT,BROWNOUT,NOLVP
#use delay(clock=4M)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7, ERRORS)

int1
skipmeK[96]={1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1
,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,
1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1};

void setskipK (int1 prx , unsigned int8 t) {
      unsigned int8 q;
      skipmek[t]=!prx;
      printf("InDeX %u : ",t,);
      for (q=0; q<12; q++) {
            printf("%1d ", skipmek[q]);
     }
     printf("\r\n");
}

//======================================
void main(void) {
    int8 t;

    for(t=0; t<12; t++)
        setskipK(1, t);

    while(1);
}

and it merrily works with every version I have tried. 4.099 and up...

Best Wishes

Stupid me .... this is a small part of a program that uses 85% of a 18f4525
AND I had reduced the code I posted w/o enough care.

This was actually the old core
Code:

      if (maxchannel){
          if (prx)  skipmek[t]=0;   // inverts prx
            else      skipmek[t]=1;
       }     

maxchannel is a global retrieved from flash storage
and I was forgetting to call the flash readback function
such that maxchannel was =0 when I tried it with 4.135


However I do very much appreciate that I was able, with outside help, to overcome the mental block and solve this.
Sincere thanks and an apology for wasting the time of others
when I should have been more thorough myself.
