Crazy problem

[Marco Ramos]

Hi guys, I normaly program my PIC in assembly, already did with C too in 16F PIC family. Recently I try program PIC18F4550 and simple dont happens nothing. I want just put some PORT to high to on leds and honestly I dont know what is the issue. Im using CCS compiler in MPlAB. No compile error, write well to the pic, but non tension in the PORTC.

The code is:

 

#include<18f4550.h>                     //Directiva de compilaçao

 

 

#use delay(clock=4000000)

 

#fuses   INTRC_IO      

#fuses   NOWDT         

#fuses   PUT           

#fuses   NOPROTECT   

#fuses   NOBROWNOUT

#fuses   NOLVP

#fuses   NOCPD

#fuses MCLR

 

#byte trisc=0xF94 

#byte portc=0xF82

#byte latc=0xF8B 

 

void main()

{

      portc=0x00;

      latc=0x00;

      trisc=0x00;

      while(1)

     {

          portc=0xff;

         delay_ms(500); 

         portc=0X00;

         delay_ms(500);

     }

}

 

Help me please!

Already works! CCS compiler version was the problem, it works in 16F but with 18F not. Reinstal ccs again solve my problem.
