bufferVar.clear()
This function clears all readings and statistics from the specified buffer.
Type TSP-Link accessible
Affected by Where saved Default value
Function
Yes
Usage
bufferVar.clear()
bufferVar
The name of the reading buffer, which may be a default buffer (defbuffer1 or
defbuffer2) or a user-defined buffer
Example
reset()
testData = buffer.make(50)
trigger.model.load("SimpleLoop", 3, 0, testData)
trigger.model.initiate()
waitcomplete()
printbuffer(1, testData.n, testData)
testData.clear()
print("Readings in buffer after clear ="
.. testData.n)
trigger.model.initiate()
waitcomplete()
printbuffer(1, testData.n, testData)
Create a reading buffer named
testData, make three readings and
store them in testData, and then view
the readings.
Print number of readings in testData.
Output:
