PRL_Reader_Buffer

The Snapshooter reads data from the Access Buffer. There are two main ways of usage:

  1. Inserting the VI in a timed loop will read data from the Access Buffer at regular intervals. By keeping the input and output time stamps the VI will return only new data. The amount of data received each time may vary, since at a data rate of 50, there is only 20 ms between each new data frame.

  2. By activating the Get Full Buffer option, the VI will return the full buffer each time it is used. The length of this buffer is set in the PRL configuration. This is useful for making a sliding FFT or similar operations that require a fixed length buffer at regular intervals.

Inputs:

Get Full BufferIgnores the input time stamp and return
Get All SignalsSkips the signal filtering made by the Channel Selector, and Sends all available signals to the data outputs

Outputs:

Time StampTimestamp array
Phasor SignalsPhasor data array
Analog SignalsAnalog data array
Digital SignalsDigital data array
Has DataIndicate if new data has been found
First Buffer FilledReturns false until the buffer has been filled, it will remain filled since it is rotating buffer.
