Your code is calling a location that isn't valid.

Post your code..
 
void main() {
trisb= 0b000000000; //portb is output , program port b is output
portb=0 ; // all leds is off
for ( ;; ) {
portb= 0b00101011 ;
delay_ms (10000) ;
portb = 0b11010100 ;
delay_ms(10000) ;
}
}
 
Okay... Uncheck all the libraries in the library manager.... I don't think you need any for that code..
 
There is nothing wrong with that code...
The error window in Labcenter Proteus shows you have a pic location violation!!! MikroC is compiling the hex file wrong.

In MikroC make sure all the libraries in Library manager are unchecked... Also make sure the project is set for a pic16f877..
 
can you explain to me by screen shoot , hoe can i fix hex file from Micro C ?
 
whats wrong in this script

void main() {
char x;
trisb=0 ;
portb= 0;
for ( ; ; ) {
portb=0b0 ;
delay_ms(1000) ;
for (x=0 ; x<<8 ;x++ ) {
portb=portb<<1 ;
delay_ms(1000) ;
}
}
}
 
What is PIC168771 as you appear to be trying to compile for it. See line 9 of above image.

It's a Proteus thing... The correct part is modelled... That is the library part

I have now a copy of microC and compiled your code and run in Proteus... No problem at all
