Issue on Internal oscillator selection in PIC16f886

Hi frnds

I have problem in Internal oscillator selection in PIC16f886. I tried the following code, its not working.
Configuration bits declaration error will come.

Code:

#include <htc.h>

// 13-1 12-0 11-0 10-0 9876-0 5-1 4-1 3-0 100
//__CONFIG(0x2034);
//__CONFIG _CONFIG2(0X0100);

__CONFIG _CONFIG1(FOSC_INTRC_NOCLKOUT & WDTE_OFF & PWRTE_OFF & MCLRE_ON & CP_OFF & CPD_OFF & BOREN_ON & IESO_OFF & FCMEN_ON & LVP_ON)
__CONFIG _CONFIG2(BOR4V_BOR40V & WRT_OFF);

void main()
{
int value;
TRISA=0x00;
PORTA=0x00;
TRISB-0x00;
PORTB=0xFF;

OSCCON= 0b01100101;
OSCTUNE= 0x0E;
while(1)
{
PORTB=0xFF;
for(value=0;value<10000;value++);
for(value=0;value<10000;value++);
PORTB=0x00;
for(value=0;value<10000;value++);
for(value=0;value<10000;value++);
}
}

Configuration bits declaration error will come.

You didn't report an actual error.

hello,


you have analog input on reset !

A trivial compiler usage problem. Each compiler has specific symbols for fuse bits and include files that must be imported to make it known. Apparently you didn't get it right.

I presume it's well explained in a compiler user manual and demonstrated in example projects. You didn't tell which compiler was used.

Iam using MPLAB X IDE, Hitech C compiler
