Function Documentation

◆ ngcppAckData()

void ngcppAckData ( void )

Acknowledge that the current data buffer has been processed.

◆ ngcppCapture()

void * ngcppCapture ( void * arg )

Capture thread

◆ ngcppCheckStop()

char ngcppCheckStop ( void )

Check if the data capture has been stopped.

◆ ngcppDivide()

void ngcppDivide ( int num )

Divide the DMA in sub-divisions (soft-interrupts).

◆ ngcppFlushInput()

int ngcppFlushInput ( void )

Skip all buffers in the input-ring-buffer. It returns the number of buffers that have been skipped.

◆ ngcppInit()

int ngcppInit	(	ngcpp_dma_t *	dev,
		unsigned int *	doneCount,
		char *	erms )

Initialize the DMA read and synchronize doneCount to the actual buffer count in the DMA driver.

◆ ngcppIppApply()

int ngcppIppApply	(	int	id,
		void *	param,
		int	n,
		char *	erms )

◆ ngcppIppCfg()

void ngcppIppCfg	(	int	id,
		void *	param,
		int	n )

◆ ngcppOverrun()

char ngcppOverrun ( ngcpp_dma_t * dev )

Checks if the ringbuffer did get full.

◆ ngcppStartCapture()

int ngcppStartCapture ( void )

Start the data capture loop.

◆ ngcppTerm()

int ngcppTerm	(	ngcpp_dma_t *	dev,
		char *	erms )

Terminate all DMA transfers

◆ ngcppTermProcessing()

void ngcppTermProcessing ( void )

Acknowledges that processing loop has been stopped.

◆ ngcppWaitData()

int ngcppWaitData ( ngcpp_t ** res )

Waits for the next data semaphore and returns a pointer to the next data input buffer. The return value is the number of frame that has been skipped during a pause.

◆ ngcppWaitStart()

int ngcppWaitStart ( void )

Wait until data capture has been started.
