hi guys i am using pic 16f877 and max 517 ... i have written a programme and it is giving an error can any body check what i did wrong:

Code:

#include <16F877.h>

#device ICD=TRUE
#device ADC=10 // Use 10bits ADC
#fuses HS,NOWDT,NOPROTECT,NOLVP
#use delay(clock=20000000) // 16Mhz Crystal is Used

#include <MAX517.c> //Call for MAX517.c function

#define TRIGGER = PIN_E0
#define SAMPLE1 = PIN_C4
#define SAMPLE2 = PIN_D2
#define SAMPLE3 = PIN_C5

int1 data_end = 0;

void main(void)
{
set_tris_d( 0xff );
set_tris_c( 0xbf );
set_tris_e( 0xff );

Begin:

if (TRIGGER)//<-- A numeric expression must appear here what i did wrong cant find out
      {
   data_end = 0 ;
   }
else
   goto Begin ;

while(1)
{
if (!TRIGGER && !data_end)
      {
   if (!SAMPLE1)

      {
         output_high(PIN_A0); //LED ON
         write_dac(0xFF); //DAC output 5V
   delay_ms(5000); //Delay

   output_low(PIN_A0); //LED OFF
   write_dac(0x00); //DAC output 0V
   delay_ms(5000); //Delay
      data_end = 1 ;
      }
   else
         if (!SAMPLE3)

      {
         output_high(PIN_A0); //LED ON
         write_dac(0xFF); //DAC output 5V
   delay_ms(5000); //Delay

   output_low(PIN_A0); //LED OFF
   write_dac(0x00); //DAC output 0V
   delay_ms(5000); //Delay
      data_end = 1 ;
      }
      }

   else
   goto Begin ;
}

}

Looking forward for help

Code:

#define TRIGGER = PIN_E0

change to

Code:

#define TRIGGER PIN_E0
