File Sink

Used to write a stream to a binary file. This file can be read into any programming environment that can read binary files (MATLAB, C, Python, ...). It can also be played back in GRC using a File Source. For example, if complex type is chosen, then the binary file will be full of float32s in IQIQIQ order. There is no meta data or anything else included with the binary data.

Parameters

(R): Run-time adjustable

File (R)

Name of the file to open and write output to.

Unbuffered

Specifies whether the output is buffered in memory. If the output is unbuffered, the data will be flushed to the file each time the work function is called. This can cause the flowgraph to run slow due to the time required to access the disk each time.

Append File

Whether or not to append to file, or create a new file each time.

Example Flowgraph

Insert description of flowgraph here, then show a screenshot of the flowgraph and the output if there is an interesting GUI. Currently we have no standard method of uploading the actual flowgraph to the wiki or git repo, unfortunately. The plan is to have an example flowgraph showing how the block might be used, for every block, and the flowgraphs will live in the git repo.
