Data Acquisition Toolbox

Functions - By Category

This section contains brief descriptions of all toolbox functions. The functions and the device objects they are associated with are categorized according to usage. The supported device objects include analog input (AI), analog output (AO), and digital I/O (DIO).

A number of other MATLAB M-file helper functions are provided with this toolbox to support the functions listed below. These helper functions are not documented because they are not intended for direct use.

Creating Device Objects		AI	AO	DIO
analoginput	Create an analog input object.
analogoutput	Create an analog output object.
digitalio	Create a digital I/O object.

Adding Channels and Lines		AI	AO	DIO
addchannel	Add hardware channels to an analog input or analog output object.
addline	Add hardware lines to a digital I/O object.
addmuxchannel	Add hardware channels when using a multiplexer board.

Getting and Setting Properties		AI	AO	DIO
get	Return device object properties.
set	Configure or display device object properties.
setverify	Configure and return the specified property.

Executing the Object		AI	AO	DIO
start	Start a device object.
stop	Stop a device object.
trigger	Manually execute a trigger.
waittilstop	Wait for the device object to stop running.

Working with Data		AI	AO	DIO
flushdata	Remove data from the data acquisition engine.
getdata	Extract data, time, and event information from the data acquisition engine.
getsample	Immediately acquire one sample.
getvalue	Read values from lines.
peekdata	Preview most recent acquired data.
putdata	Queue data in the engine for eventual output.
putsample	Immediately output one sample.
putvalue	Write values to lines.

Getting Information and Help		AI	AO	DIO
daqhelp	Display help for device objects, constructors, adaptors, functions, and properties.
daqhwinfo	Display data acquisition hardware information.
daqpropedit	Open the Data Acquisition Property Editor.
propinfo	Return property characteristics for device objects, channels, or lines.

General Purpose		AI	AO	DIO
binvec2dec	Convert binary vector to decimal value.
clear	Remove device objects from the MATLAB workspace.
daqcallback	A callback function that displays event information for the specified event.
daqfind	Return device objects, channels, or lines from the data acquisition engine to the MATLAB workspace.

delete	Remove device objects, channels, or lines from the data acquisition engine.
disp	Display summary information for device objects, channels, or lines.
ischannel	Check for channels.
isdioline	Check for lines.
isvalid	Determine whether device objects, channels, or lines are valid.
length	Return the length of a device object, channel group, or line group.
load	Load device objects, channels, or lines into the MATLAB workspace.
makenames	Generate a list of descriptive channel or line names.
muxchanidx	Return multiplexed scanned channel index.
