| Internal Error when using printf and lcd_putc |

Please for help,
in this subroutine I get the following error when compiling:
Error 44 "main.c" Line 269(1,1), internal error - Contact CCS LABEL SCR=1677
LCD Driver http://www.ccsinfo.com/forum/viewtopic.php?t=24661&highlight=lcd
SWITCHES - http://www.ccsinfo.com/forum/viewtopic.php?t=22145&highlight=button
subroutine
| Code: |
void main_menu(void)
{
int1 exit=0;
int8 menu_marker=0;
lcd_gotoxy(1,1);
lcd_putc("Setting \n");
lcd_putc(" times ");
delay_ms(1500);
lcd_putc("\f");
do{
switch(menu_marker){
case 0: lcd_gotoxy(1,1);
lcd_putc("Time 1i\n");
printf(lcd_putc, "%3d sec", time1); //line 269
delay_ms(30);
while(!scroll_click && !set_click);
if(set_click) {incrdecr1(time1,59,1,1,2,2); write_eeprom(0,time1); menu_marker=0;}
else if(scroll_click) menu_marker=1;
break;
case 1: lcd_gotoxy(1,1);
lcd_putc("Time 1p\n");
printf(lcd_putc, "%3d sec", time1p);
delay_ms(30);
while(!scroll_click && !set_click);
if(set_click) {incrdecr1(time1p,59,1,1,2,2); write_eeprom(1,time1p); menu_marker=1;}
else if(scroll_click) menu_marker=2;
break;
case 2: lcd_gotoxy(1,1);
lcd_putc("Time 2i\n");
printf(lcd_putc, "%3d sec", time2);
delay_ms(30);
while(!scroll_click && !set_click);
if(set_click) {incrdecr1(time2,59,1,1,2,2); write_eeprom(2,time2); menu_marker=2;}
else if(scroll_click) menu_marker=3;
break;
case 3: lcd_gotoxy(1,1);
lcd_putc("Time 2p\n");
printf(lcd_putc, "%3d sec", time2p);
delay_ms(30);
while(!scroll_click && !set_click);
if(set_click) {incrdecr1(time2p,59,1,1,2,2); write_eeprom(3,time2p); menu_marker=3;}
else if(scroll_click) menu_marker=4;
break;
case 4: lcd_gotoxy(1,1);
lcd_putc("Time 3i\n");
printf(lcd_putc, "%3d min", time3);
delay_ms(30);
while(!scroll_click && !set_click);
if(set_click) {incrdecr1(time3,59,1,1,2,2); write_eeprom(4,time3); menu_marker=4;}
else if(scroll_click) menu_marker=5;
break;
}
if(scroll_click && menu_marker==5)
{menu_marker=0;
lcd_gotoxy(1,1);
lcd_putc(" Exit? \n");
lcd_putc("push set");
delay_ms(30);
while(!scroll_click && !set_click);
if(set_click) exit=1;
else exit=0;
}
}While(!exit);
lcd_gotoxy(1,1);
lcd_putc(" Save \n");
lcd_putc("settings");
delay_ms(2000);
read_store_value_and_start();
enable_interrupts(INT_TIMER0);
} |
The error appears on lines with lcd_putc and printf, I think it gets in conflict with lcd_gotoxy(1,1) and \n, but it exists and where the use lcd_goto(1,2) instead of \n. |

Post your PIC and #fuses and #use delay(), and your compiler version
so a test program can be made. |

Not for the first time using such a short menu, but my first time going to an error.  |

I put together a test program and I am getting the Internal Error message.
I'll look at it and see if I can find the problem. |

Thank you very much for your attention.
Still learning and I will be interested to know if the problem is me. |

The error message disappears if I comment out the #opt 11, which is
sort of to be expected. My basic rule is "don't push the compiler". |

So I wrote the code that is not efficient enough to be optimized ... Is this supposed to mean?
Thanks for the advice PCM programmer! |

NO, it means what he said. Don't push the limits of the compiler". If you
want that kind of optimization go buy the $1800 compiler.
Any compiler is going to have problems if you try to push the amount of
optimization to the extreme. Unless you are a professional programmer
writing critical code you very likely don't need it anyway. If you are a
student you certainly do not. If you want more optimization then code in
assembly..
My apologies for jumping in PCM, I just couldn't let this lie...

I am not a student anymore.
I am interested in programming, and teach myself as far as I can.
Thank you all. |
