Function Documentation

void sysBusProbe	(	unsigned int *	lclAdr,
		int	readwrite,
		int	size,
		unsigned int *	result
	)

VxWorks routine to probe the bus, either PCI or VME.

Routine was not provided as part of a header file, so forced to include and document here. Consult the real VxWorks documentation for how this really works.

Referenced by VME_probe().

void sysProbeErrClr

(

void

void sysVmeProbe	(	unsigned int *	lclAdr,
		int	readwrite,
		int	size,
		unsigned int *	result

volatile unsigned int * toLocal

(

unsigned int

vmeAdr

)

[static]

Inline VME to local address translation routine.

Parameters:

vmeAdr

The VME address to translate.

Returns:

The translate address.

Utility to translate a VME address to its local address equivalent. This routine is only used within the context of this file. The public interface is VME_toLocal.

int VME_probe

(

volatile unsigned int *

lclAdr

)

Does a read probe of lclAdr.

Parameters:

lclAdr

The local address representation of the VME address to probe.

Returns:

0 if the address is valid, 1 if it is not.

Does a read probe of the specified address on the VME bus. This function can be used as a map function of the VME crate. This routine works only on addresses with are 32 bit readable.
