lcd & pic16f648a
PostPosted: Thu Oct 15, 2009 1:41 am     Reply with quote
I am trying to program the PIC16F48a to drive an LCD to display temperature. The program doesn't compile :(. Are the CCS internal LCD controller functions compatible with the PIC16F648a?

Particularly, I'm realizing a receiver circuit to display the measure of environment temperature.

This is the receiver code:
Code:

#include "C:\Documents and Settings\Administrator\Desktop\ricevitore\16f648.h"
#define LCD_ENABLE_PIN PIN_D0
#define LCD_RS_PIN PIN_D1
#define LCD_RW_PIN PIN_D2
#define LCD_TYPE 2
#include <lcd.c>

int1 stato_bit, stato_id, parita;
int1 vett[48];
int i, j, k1, k2, count, count_k, pos_id;


#int_CCP1
void  CCP1_isr(void)
{
   enable_interrupts(INT_TIMER0);
   enable_interrupts(GLOBAL);
   set_timer0(0);
   
   delay_us(500);
   stato_bit=input_state(pin_B3);
   
   if(stato_bit)
      vett[j]=1;
   else
      vett[j]=0;
   
   if(j==47)
         j=0;
   else
      j++;
   
   if (get_timer0()<255)
      disable_interrupts(INT_TIMER0);
}


#int_TIMER0
void  TIMER0_isr(void)
{
   stato_id=false;
   parita=false;
}

void controllo_id (int1 v[48])
{
   for(k1=0;k1<32;k1++)
   {
      count_k=0;
      for(k2=k1;k2<k1+15;k2++)
      {
         if((v[k2]==1)&&(v[k2+1]==0))
            count_k++;
      }
     
      if(count_k==8)
      {
         stato_id=true;
         pos_id=k1;
      }
      else
         stato_id=false;
   }
}

void controllo_parita (int1 v[48])
{
      for(i=0;i<48;i++)
      {
         if(vett[i]==1)
            count++;
      }
      if(count%2==1)
         parita=false;   
      else
         parita=true;
}


void main()
{
   setup_timer_0(RTCC_INTERNAL|RTCC_DIV_8); // va in overflow ogni 2ms
   setup_timer_1(T1_INTERNAL|T1_DIV_BY_1);
   setup_timer_2(T2_DISABLED,0,1);
   setup_ccp1(CCP_CAPTURE_RE);
   // set_pwm1_duty(0);
   setup_comparator(NC_NC_NC_NC);
   setup_vref(FALSE);
   enable_interrupts(INT_CCP1);
   enable_interrupts(GLOBAL);
   setup_oscillator(OSC_4MHZ);
   
   lcd_init();

   while(TRUE)
   {
     
      controllo_id (vett);
     
      if(stato_id==true)
      {
         controllo_parita(vett);
      }
     
      if((pos_id==0)&&(stato_id==true)&&(parita==true))
         
         
         // comandi lcd
         
         delay_us(1);
     
     
   }

}

And these are the error messages:

Undefinied identifer set_tris_d

about:

set_tris_lcd(LCD_READ); / set_tris_lcd(LCD_WRITE);

Someone can help me?? Thank a lot!

You are telling the LCD code, to use PORTD for the LCD control:

#define LCD_ENABLE_PIN PIN_D0
#define LCD_RS_PIN PIN_D1
#define LCD_RW_PIN PIN_D2

Your PIC, _does not have a PORTD_.

Yes, the LCD code will work with a 648, if it is setup to use the pins the chip has. _but_, not if you try to use pins that are not there....

Best Wishes
