vtex1629_get_lxibus_input
FUNCTION PROTOTYPE
ViStatus vtex1629_get_lxibus_input (ViSession vi, ViPInt32 input);
FUNCTION PARAMETERS
vi = contains a session handle to the instrument. This handle is obtained by the function and remains valid until the
session is closed.
input = an integer return value, that indicates the current input state of each LXI Trigger Bus channel. Valid return
values: 0 to 255.
DATA ITEM RESET VALUE
Not applicable to this function.
DESCRIPTION
This function queries and returns the input state of each of the channels on the LXI Trigger Bus. The input
parameter is an 8-bit integer where the least significant bit of the integer corresponds to LXI Trigger Bus channel
zero and the most significant bit corresponds to LXI Trigger Bus channel seven.
If, for example, the value 129 (0x81) is returned, this corresponds to the 8-bit number 1000 0001. This indicates that
LXI Trigger Bus channels zero and seven are currently inputting high signals while the other channels are inputting
low signals.
EXAMPLE
ViSession instrumentHandle;
ViStatus status;
ViInt32 ins;
