Overview 

Write to files periodically and erase the data.

 

Description

You may want to write to file less frequently and after a certain number of iterations of some Data Acquisition task. In this example, the DAQ assistant acquires data into the block diagram, the data is built, iteration by iteration, into a larger, compiled array. Then, after a certain number of iterations (10 in this case) all the data can be written to a file and the array and count are erased. The file writing method is left up to the user in this case. You can write to a text file, spreadsheet file, binary file, etc. The DAQ Assistant can be replaced with other types of data acquisition or generation nodes.
