hpe1437_lbus_mode

Sets the local bus mode. This description also includes the query:

hpe1437_lbus_mode_get gets the current local bus mode.

VXIplug&play Syntax

#include "hpe1437.h"

ViStatus hpe1437_lbus_mode(ViSession id, ViInt16 lbusMode);

ViStatus hpe1437_lbus_mode_get(ViSession id, ViPInt16 lbusModePtr);

Description

hpe1437_lbus_mode sets the local bus to either generate, append, insert or pipeline

data. The data port must be set to the local bus with the hpe1437_data_port function

before these modes take effect.

Parameters

id is the VXI instrument session pointer returned by the hpe1437_init function.

lbusMode selects the transmission mode of the local bus when it is enabled by the

hpe1437_data_port function. HPE1437_GENERATE forces the module at id to

generate data only, not passing through data from other modules on the local bus.

HPE1437_APPEND causes the E1437 to pass data through from modules on its left

and append its data to the end. HPE1437_INSERT causes the E1437 to place its data

on the local bus and then pass data through from modules on its left.

HPE1437_PIPELINE causes the E1437 to pipe data through from modules on its left

without appending or inserting its own data. The state of this parameter is unaffected

by switching back and forth between the local bus and the VME backplane with the

hpe1437_data_port function.

Module(s) to Left

lbusModePtr contains the current value of the lbusMode parameter.
