Input() Function

Posted: Thu Mar 02, 2006 9:23 am

Guys

I has some issue with input() function,
My code is below:

Code:

#include <18F2525.h> // Call for PIC18F2525 Driver
//#device ICD=TRUE
#device ADC=10 // Use 10bits ADC
#fuses HS,NOWDT,NOPROTECT,NOLVP
#use delay(clock=16000000) // 16Mhz Crystal is Used
#use rs232(baud=9600, parity=N, xmit=PIN_C6, rcv=PIN_C7, bits=8)

#include <MAX517mod.c>
#byte PORTB = 0xf81
#byte PORTC = 0xf82

#include <stdlib.h>
#include <math.h>

//Start main program
void main()

{

// ADC Port Initialisation
setup_port_a( AN0_TO_AN3 | VSS_VDD );
setup_adc( ADC_CLOCK_INTERNAL );

while(1)

{

output_high(PIN_C5); // Power On LED
delay_us(100);

while ( !input(PIN_A2) );

// waits for freq ready signal from A2

output_low(PIN_C5);//LED OFF

printf("\n\r we got A2 signal ON");

}

}

Even though I tied PIN_A2 with 5V.... It won't proceed the later "printf" statment....

Did I miss something?
Do I have to define PORT A as INPUT??(SET_TRIA???)

thx in advance...
