Internal oscillator of PIC16f884 doesn't change frequency in the following code:
#pragma config BOREN=0,IESO=0,FOSC=INTRC_NOCLKOUT,MCLRE=1,WDTE=0,CP=1,LVP=0
volatile unsigned char counter = 0;
void setup( void )
{
ANSEL = 0x00; // all digital
TRISD = 0x00; // all RD is output
//
OSCCONbits.IRCF2 = 0;
OSCCONbits.IRCF1 = 0;
OSCCONbits.IRCF0 = 0;
OSCCONbits.SCS = 1;
while(!OSCCONbits.HTS);
//interrupt timer0
IRCF0 = 1;
IRCF1 = 1;
IRCF2 = 1;
}
No matter what values I assign to OSCCONbits.IRCFx
the clock speed (as measured with a blinky light) never changes... The only other way that this could seem to behave this way, is if _delay
were to somehow adjust for constant time rather than clicks, but I don't think that is the case.
EDIT: I am dumb...
why doesn't this work
int i = 0;
int *p = &i;
i = 0 // no matter what i change this to i is always one.... dumb
*p=1
