Counter And Timer Control
The Counter and Timer control feature allows you to:
Create a function generator
Keep a count of how many times a signal has fired.
Use the CounterSelector to select a counter, either 0 or 1.
Use CounterEventSource to select the event to increment the counter. Possible counter event sources include:
- MHz Tick
- Line Inputs
- User Outputs
- Counter Starts
- Counter Ends
- Logic Block Outputs
- Exposure Start
- Exposure End
- Frame Trigger Wait
When the selected source allows for signal activation, use CounterEventActivation to specify Level Low, Level High, Falling Edge, Rising Edge, or Any Edge.
Use CounterDelay to indicate the maximum number of counts that need to occur before generating the Counter Start event.
Use CounterDuration to indicate the maximum number of counts that need to occur before generating the Counter End event.
Note: Only one of CounterTriggerSource or CounterResetSource can be active at a time. Selecting one disables the other.
Use CounterTriggerSource to select the event to start the counter. Possible counter trigger sources include:
- MHz Tick
- Line Inputs
- User Outputs
- Counter Starts
- Counter Ends
- Logic Block Outputs
- Exposure Start
- Exposure End
- Frame Trigger Wait
When the selected source allows for signal activation, use CounterTriggerActivation to specify Level Low, Level High, Falling Edge, Rising Edge, or Any Edge.
Use CounterResetSource to select the event to end the counter. Possible counter reset sources include:
- MHz Tick
- Line Inputs
- User Outputs
- Counter Starts
- Counter Ends
- Logic Block Outputs
- Exposure Start
- Exposure End
- Frame Trigger Wait
When the selected source allows for signal activation, use CounterResetActivation to specify Level Low, Level High, Falling Edge, Rising Edge, or Any Edge.
CounterValue indicates the current counter while CounterStatus indicates the current status. CounterValueAtReset indicates the counter's value when a reset occurred.
