Detailed Description

A utility / example program to demonstrate the EDT PCD library's ring buffer mode. This application either reads data from a file/device or can generate counter data. Data is DMA'd from host to the opened EDT device.

Function Documentation

usage()

void usage	(	const char *	progname,
		const char *	err
	)

Display usage information.

Parameters

progname	The name of this program.
err	A description of what is invalid about the call.

init_buf()

void init_buf	(	unsigned char *	buf,
		unsigned int	size,
		unsigned int	numbufs
	)

Initialize buffer with 16-bit incremented data. This could be replaced with read of data from file, data from device device, or some other ingestion method.

Parameters

buf	The buffer to initialize.
size	The size of buf.
numbufs	The number of buffers.

main()

int main	(	int	argc,
		const char *	argv[]
	)

Send DMA data.
