Rising or falling edges of EdgeCount signals

Description

When working with the session-based interface, use the ActiveEdge property to represent rising or falling edges of a EdgeCount signal.

Values

You can set the Active edge of a counter input channel to Rising or Falling.

Examples

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

Data acquisition counter input edge count channel 'ctr0' on device 'Dev2':

      ActiveEdge: Rising
  CountDirection: Increment
    InitialCount: 0
        Terminal: 'PFI8'
            Name: empty
              ID: 'ctr0'
          Device: [1x1 daq.ni.DeviceInfo]
 MeasurementType: 'EdgeCount'

Change the Active Edge property to 'Falling':

ch.ActiveEdge = 'Falling'
ch = 

Data acquisition counter input edge count channel 'ctr0' on device 'Dev2':

      ActiveEdge: Falling
  CountDirection: Increment
    InitialCount: 0
        Terminal: 'PFI8'
            Name: empty
