This block represents a variable that can be read from a config file.
This is the template for the [[:Category:Block_Docs|"Page-per-block Docs"]].  This first section should describe what the block does and how to use it, using however many paragraphs necessary.  Note that the title of the wiki page should match the block's name in GRC, i.e. the one defined in the block's .grc file.  Look at the [[FFT]] Block for a good example.


As this is a basic template, it's also in the [[:Category:Stub_Docs|"Stub Docs category"]]. Please improve it.
To save the value back into the config file: enter the name of another variable into the writeback param. When the other variable is changed at runtime, the config file will be re-written.

This block represents a variable that can be read from a config file.

To save the value back into the config file: enter the name of another variable into the writeback param. When the other variable is changed at runtime, the config file will be re-written.

Parameters

(R): Run-time adjustable

Id (R)
Id of the block, used to reference the variable in other blocks
Default value (R)
Default value
Config file (R)
The file that stores the value
Section (R)
Section in the file containing the key/value pair of the variable
Option (R)
Key of the value in the file
WriteBack (R)
Variable to write in place of the current one

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.
