Hi Ren, while (1){

Hi Ren,

 

while (1)

{

          if (PORTBbits.RB4=1)               //THIS IS NOT A CONDITIO, BUT AN ASSIGNMENT STATEMENT

                  (PORTC=0xff);

}

 

The correct coding is,

 

while (1)

{    
             if (PORTBbits.RB4==1)          //SEE THE LOGICAL OPERATOR “==”
                        (PORTC=0xff);       
}    
 

You should practice more  C coding and I hope you won’t do these kind of silly mistakes again
