Program will only work in MPLAB simulator
PostPosted: Sun Jun 06, 2004 2:06 pm     Reply with quote
Dear PCM users,

I have recently bought the PCM compiler, I am having problem with the following code:

Code:

#if defined(__PCM__)
#include <16F874.h>
#device ICD=TRUE
#fuses XT,NOWDT,NOPROTECT,NOLVP,NOPUT,NOBROWNOUT
#use delay(clock=4000000)
#endif

#include <lcd.c>







int sec=0; //second
int min=0;//minute
int hrs=0; //hour
int milli=0;
int increment = 0;
int flag=0;
int data=0;


void display()
   {   
          
      if (flag==1)
      {
         lcd_gotoxy(0,1);
         printf(lcd_putc,"%02U:%02U",hrs,min);      
      }
      else
      {
         lcd_gotoxy(1,1);
         printf(lcd_putc,"%S",data);   
      }   
   }   
#int_rtcc
void clock_isr()
{
    increment++;
   if (increment==2)
   {   milli++;
      increment=0;
   }
   if (milli==10) // 10*100ms = 1second passed
   {
      sec++;
      milli=0;
   }   
   if (sec==60) // 60*1sec = minute
   {
       sec=0;
       min++;
       flag=1;
   }
   if (min==60)
   {
      min=0;
       hrs++;
      flag=1;
   }
   
   if (hrs==24)
   {
      sec=0;
      hrs=0;
      flag=1;
   }
   if (milli < 10) //milli lower than 10 exit after incrementing milli
      set_RTCC(60); //setup TMR0 to count upto 100ms
      
}   


   
   



void main()
{
    lcd_init();

   set_RTCC(60);
   setup_counters(RTCC_INTERNAL,RTCC_DIV_256);
   enable_interrupts(INT_RTCC);
      enable_interrupts(GLOBAL);

   while (1)
   {
      if (flag==1)
      {
         display();
         flag=0;
      }   
      
   }
}


The code is for a rel time clock on the LCD (CCS LCD DRIVERS),
the interrupt happens every 49ms - using timer0
When I use MPLAB sim it works as it should, but if i blow it onto the chip I get nothing on the display.

I have tested the LCD, PIC, connectivity.

Can anyone program my code into a PIC or find any mistakes

I hope someone can help

I tested it with PCM vs. 3.188. I changed the printf statements
to send output directly to the PC terminal window, because I don't
have a LCD on my demo board.

I also added one line to your int_rtcc function, so that it would
display output every second, instead of every minute.
That's better for a test program.

Then it worked. It displayed this every second:

00:00


if (milli==10) // 10*100ms = 1second passed
{
sec++;
milli=0;
flag = 1; // Add this line to get output every 1 second.
}
