Method Summary

int	getPeriodLengthInTicks()
int	getTickLengthInMicroSeconds()
void	setDutyLength(int dutyTicks)

Method Detail

getPeriodLengthInTicks

int getPeriodLengthInTicks()

Returns:

the number of cycles into which a single PWM period is divided.

setDutyLength

void setDutyLength(int dutyTicks)

Parameters:

dutyTicks - the number of cycles within a single PWM period for which the output is to be switched on. So
setDutyLength(0);
leaves the output at 0 while
setDutyLength(getPeriodLengthInTicks());
turns it on fully.

getTickLengthInMicroSeconds

int getTickLengthInMicroSeconds()

Returns:

the length in micoseconds of a single cycle, i.e. the length of a PWM period (in microseconds) divided by the number of cycles within a period.
