Usage
fillMode = bufferVar.fillmode

fillMode
Fill the buffer, then stop: 0 or buffer.FILL_ONCE
Fill the buffer continuously: 1 or buffer.FILL_CONTINUOUS
bufferVar
The name of the reading buffer, which may be a default buffer (defbuffer1 or
defbuffer2
) or a user-defined buffer
Details
When a reading buffer is set to buffer.FILL_ONCE, no data is overwritten in the buffer. When the buffer is
filled, no more data is stored in that buffer and new readings are discarded.
When a reading buffer is set to buffer.FILL_CONTINUOUS, the oldest data is overwritten by the newest data
after the buffer fills.
When a reading buffer is set to buffer.FILL_CONTINUOUS, the first new measurement is stored at n+1, where
n is the number of readings stored in the buffer.
