Member Function Documentation

◆ getPeriodAndSkipFactor()

void CmtDeviceMode::getPeriodAndSkipFactor	(	uint16_t &	period,
		uint16_t &	skip
	)		const

Compute the period and skip factor.

This function computes the period and skipFactor fields from the stored m_sampleFrequency field. The maximum error in the frequency is approximately 0.4%, which occurs at 510Hz (= actually 512 Hz). In general, the higher frequencies are harder to set up exactly.

◆ getRealSampleFrequency()

double CmtDeviceMode::getRealSampleFrequency ( void ) const

Return the real sample frequency in Hz.

This may be up to 2Hz different from the value that is set.

◆ operator==()

bool CmtDeviceMode::operator== ( const CmtDeviceMode & dev ) const

Check if all fields of the two structures are equal.

◆ setPeriodAndSkipFactor()

void CmtDeviceMode::setPeriodAndSkipFactor	(	uint16_t	period,
		uint16_t	skip
	)

Compute the sample frequency from a period and skip factor.

This function does the reverse of the getPeriodAndSkipFactor function, storing the value in the m_sampleFrequency field.
