PIC16F887 Startup Problem
PostPosted: Fri Dec 07, 2007 12:21 pm     Reply with quote

Hello All,

I have a problem getting my pic to run. The board works, because it works in assembly. I am sure it's my config setup. I'm using ver 4.023 and here is the simple code:

Code:
#use delay (clock=8000000)

#fuses INTRC,NOMCLR,IESO,PUT,NOPROTECT,NOWDT,BROWNOUT,NOLVP,BORV21,FCMEN,NODEBUG
#use rs232(baud=19200, xmit=PIN_C6,rcv=PIN_C7)


void main (void)
{
   
   set_tris_C(0x00);           //allouts
   setup_oscillator(OSC_8MHZ);
 

 
   //----------
   // main loop
   //----------

   while(TRUE)
   {
     
      PORTC = 0XFF;
      delay_ms(10);
      PORTC = 0X00;
      delay_ms(10);
   }
   
}


I put a scope on portc and nothing. I'm sure it's me. What am I missing?

For starters, you have not defined the processor.

You first line should be something like:

#include <16F877A.h>


Try that and see if it works. Of course though if you did not have that in your code, I doubt it would compile without it. Did you list your whole program?

I did not list the whole file. i did have the include file. It seems that when I commented out the //#use(baud.....) the thing started working, so I guess it reserves that pinC6 for the uart. I'll get the hang of this C compiler yet Smile

Thanks for the fast reply!
