Hi,
i want your opinion about this code for PIC24FJ32GB002...I want to use
internal FRC for bus clock at 8MHz and obtain a PWM output at
150KHz...this is my first pic code and i can't test it (i haven't any
evalboard)...what do you think? This is my code

 #include <P24FJ32GB002.h>
 #define DEBUG

 _CONFIG2(IESO_OFF & FNOSC_FRC & POSCMOD_NONE)
 _CONFIG1(JTAGEN_OFF & ICS_PGx2 & FWDTEN_OFF)



 int main (void)
 {
	CLKDIV=0x00;	//clock divisor 0 => 8MHz

	#ifdef DEBUG
	REFOCONbits.ROEN=1;  //to see clock on REFO pin
	#endif

      //---150KHz PWM---
      OC1CON2bits.SYNCSEL=0b00000; //free running
      OC1RS=25;
      OC1R=25/2; //50% duty cycle
      OC1CON1bits.OCTSEL=0b111; //system clock
      OC1CON1bits.OCM=0b110;
      __builtin_write_OSCCONL(OSCCON & 0xBF);
      RPOR1bits.RP3R=18;
      __builtin_write_OSCCONL(OSCCON | 0x40);

     while(1);
     return 0;
 }

I've tried to test my firmware with mplab with logic analyzer, but
notihing comes out from REFO pin, so i need your opinion...what do you
think?
Thanks

Thanks for answer, but PIC16F is very different from 24F: so link
isn't useful...
