showdaqevents (Data Acquisition Toolbox)

Display event log information

Syntax

showdaqevents(obj)
showdaqevents(obj,index)
showdaqevents(struct)
showdaqevents(struct,index)
out = showdaqevents(...)

Arguments

obj
An analog input or analog output object.

index
The event index.

struct
An event structure.

out
A one column cell array of event information.

`obj`	An analog input or analog output object.
`index`	The event index.
`struct`	An event structure.
`out`	A one column cell array of event information.

Description

showdaqevents(obj) displays a summary of the event log for obj.

showdaqevents(obj,index) displays a summary of the events specified by index for obj.

showdaqevents(struct) displays a summary of the events stored in the structure struct.

showdaqevents(struct,index) displays a summary of the events specified by index stored in the structure struct.

out = showdaqevents(...) outputs the event information to a one column cell array out. Each element of out is a string that contains the event information associated with that index value.

Remarks

You can pass a structure of event information to showdaqevents. This structure can be obtained from the getdata function, the daqread function, or the EventLog property.

Example

Create the analog input object ai for a sound card, add two channels to it, and configure ai to execute three triggers.

ai = analoginput('winsound');
ch = addchannel(ai,1:2);
set(ai,'TriggerRepeat',2)

Start ai and display the trigger event information with showdaqevents.

start(ai)
showdaqevents(ai,2:4)
   2 Trigger#1           ( 17:07:06, 0 )          Channel: N/A
   3 Trigger#2           ( 17:07:07, 8000 )       Channel: N/A
   4 Trigger#3           ( 17:07:08, 16000 )      Channel: N/A
