How Can I Change the Debounce or Settling Time of my National Instruments Switch Device? Primary Software: Driver Software>>NI-DAQmxPrimary Software Version: 8.3 Primary Software Fixed Version: N/A Secondary Software: N/A Hardware: Switches
Problem: How Can I Change the Debounce or Settling Time of my National Instruments Switch Device? Solution: The NI-DAQmx driver can be used to change the switch debounce time stored in the switch hardware. To modify the time, call SettlingTime, a Property of DAQmx Switch Device. NI-DAQmx adds the time to the settling time of the motherboard.
Modify this time only if the default settling time is insufficient. This will modify the debounce time for all programs that access the switch, including Switch Executive.
A common use case is to change the debounce time of switches called by the Switch Executive API in TestStand. To do this, call a step in the beginning of the TestStand Sequence that references the switch and changes the settling time. This step can be in any programming language. Refer to the attached screenshot below for an example of the step in LabVIEW. Related Links: Complete Switching Tutorial Switches Home Attachments:  - settling time.JPG
