Debuger Error On Pic16f77

[messcalitto 0]

I wrote this code on SourceBoost 5.9.1 and BoostC 2.0.1

target PIC16F877

 

#include "system.h"

 

void main(void)

{

trisa = 0xff;

trisd = 0;

 

adcon1 = 0x82;

adcon0 = 0x41;

 

while(1)

{

set_bit( adcon0, GO );

while ((adcon0 & GO) == GO);

portd = adresl;

delay_ms(5);

};

}

 

 

it works fine. On debuger I configured Variable PSU -> RA0 as source of analog signal and LED Block -> PORTD as indicator to view result. It works fine.

 

I wrote simular code for target PIC16F77

 

#include "system.h"

 

void main(void)

{

trisa = 0xff;

trisd = 0;

 

adcon1 = 0x02;

adcon0 = 0x41;

 

while(1)

{

set_bit( adcon0, GO );

while ((adcon0 & GO) == GO);

portd = adres;

delay_ms(5);

};

}

 

now LED Block on PORTD doesn't indicate anything. Is this a some bug of debuger or there is some thing wrong in my code?

messcalitto,

 

The simulator doesn't support simulation of the ADC on the PIC16F77
