CSV Read/Write component

A component to simplify the task of creating and dumping data to a CSV file that can be loaded into Microcoft Excel or LibreOffice Math to create nice charts and graphs. Requires one of the File components to provide access to the file system.

Detailed description

No detailed description exists yet for this component

Examples

Simple example file to generate a two column CSV file that can be loaded into Microsoft Excel or LibreOffice Math.

The CSV Read/Write component is for simulation or App Developer.

For an embedded CSV read write see the File component

CSV Component used with App Developer -> File component: FC6 Icon.png CSV Test AD


The component requires linking to a File component to provide access to the file system for simulation and runtime, this could be the File SD, File RPI or File AppDeveloper components.
