Constructor & Destructor Documentation

tcDspDacBaseMcBsp::tcDspDacBaseMcBsp	(	tcDspMcbsp *	apMcBsp,
		tcDspOutputLatch *	apLatch,
		int	anCSID,
		int	anNumChannels
	)

This constructor is used to create an instance of the DAC base class for use with the MityDSP McBSP interface.

Parameters:

[in]	apMcBsp	Serial McBSP object that the DAC is hooked to
[in]	apLatch	Object defining a latch interface for the chip select
[in]	anCSID	ID of the DAC chip select line on the latch interface
[in]	anNumChannels	Number of channels supported by the derived DAC

Returns:

None
