Simple PWM Ouptut

​Setup timer 2 or 3 to be the timebase.  The PR value used for the timer will be the total PWM period:


	//----- SETUP TIMER 2 -----
	//Used for: PWM
	OpenTimer2((T2_ON | T2_IDLE_CON | T2_GATE_OFF | T2_PS_1_1 | T2_SOURCE_INT), 5000);

Turn on the PWM output.  The OCxRS value will be the duty cycle of the PWM signal (e.g. if set to 50% of the timers PR value you'll get a 50:50 PWM signal):


	//OC2CON
	//Used for: Piezo
	OpenOC2((OC_ON | OC_TIMER2_SRC | OC_PWM_FAULT_PIN_DISABLE), 2500, 0);		// Config, OCxRS(the PWM duity cycle to use), OCxR

(Note that the OCxR value gets loaded from the OCxRS when the timer next rolls over).

Set a new PWM duty cycle:


	OC2RS = 1250;
