resetCounters

(Not recommended) Reset counter channel to initial count

This session object function is not recommended. Use DataAcquisition object functions instead. See Version History.

Syntax

resetCounters(s)

Description

resetCounters(s) resets the current value of counter channels configured in the session object, s, to the value specified by the InitialCount property on each channel.

Tips

• Reset counters only if you are performing on-demand operations using inputSingleScan or outputSingleScan.

• Create an acquisition session and add a channel before you use this function. See daq.createSession for more information.

Examples

Reset Counters

Create a session, then add a counter channel with an EdgeCount measurement type and acquire data.

s = daq.createSession ('ni');
addCounterInputChannel(s,'cDAQ1Mod5',0,'EdgeCount');
inputSingleScan(s)

ans =

   756

Reset the counter to the default value, 0, and acquire data again.

resetCounters(s)
inputSingleScan(s)

ans =

   303

Input Arguments

s — Data acquisition session

session object

Data acquisition session, specified as a session object. Create the session object using daq.createSession. Use the data acquisition session for acquisition and generation operations. Create one session per vendor and use that vendor session to perform all data acquisition operations.

Version History

Introduced in R2011a

R2020a: session object interface is not recommended

Use of this function with a session object is not recommended. To access a data acquisition device, use a DataAcquisition object with its functions and properties instead.
