Usage
fillCount = bufferVar.fillcount
bufferVar.fillcount = fillCount
fillCount
The reading buffer fill count
bufferVar
The reading buffer; can be a dynamically allocated buffer (user-defined), or a
dedicated reading buffer (such as smua.nvbuffer1)
Details
The reading buffer fill count sets the number of readings to store before restarting at index 1. If the
value is zero (0), then the capacity of the buffer is used. Use this attribute to control when the SMU
restarts filling the buffer at index 1, rather than having it restart when the buffer is full.
If the bufferVar.fillcount attribute is set to a value higher than the capacity of the buffer, after
storing the element at the end of the buffer, the SMU overwrites the reading at index 1, the reading
after that overwrites the reading at index 2, and so on.
This attribute is only used when the bufferVar.fillmode attribute is set to smuX.FILL_WINDOW.
For dedicated reading buffers, all buffer attributes are saved to nonvolatile memory only when the
reading buffer is saved to nonvolatile memory.
Example
smua.nvbuffer1.fillcount = 50
Sets fill count of dedicated reading buffer 1
to 50.
