[nudrat]

Hello every one!!

I am using pic16f676. i want to use internal 4mhz oscillator, can any one tell me how can i configure internal oscillator settings. I mean which value i have to store in oscall register?

I am using mikroc and programing in c.

Thanks raco, for replying me.

I put the value in osccal= 0xfc(11111100), but still it won't work.

Here is my code: It just blink an led using 16f676 with internal oscillator


void main(){
PORTC = 0x00;
TRISC = 0x00;
OSCCAL = 0xfc;
while(1)
{

PORTC = ~ PORTC;
Delay_ms(100);
}

}

witing for your help.
