Detailed Description

The following class defines a hardware timer.

Constructor & Destructor Documentation

Timer::Timer	(	VoidFunctionPtr	timerHandler,
		int	callArg,
		bool	doRandom
	)

Timer::Timer Initialize a hardware timer device. Save the place to call on each interrupt, and then arrange for the timer to start generating interrupts.

Parameters

timerHandler	is the interrupt handler for the timer device. It is called with interrupts disabled every time the the timer expires.
callArg	is the parameter to be passed to the interrupt handler.
doRandom	– if true, arrange for the interrupts to occur at random, instead of fixed, intervals.

)

Timer::TimeOfNextInterrupt.

Returns

Return when the hardware timer device will next cause an interrupt. If randomize is turned on, make it a (pseudo-)random delay.
