**NOTE**: For Flair version <= 0.2.2, see [this page](old/sinus).
This page explains how to compile and test a simple program using Flair. Moreover, this program is commented to help understand how to code with Flair. You can also read Flair's documentation [page](documentation).
The program generates a sinusoidal signal, and low pass filters are added. Everything can be configured through the ground control station. This demo shows how filters are added and updated, and how to draw graphs on ground control station.
Sources are in [flair-src/demos/Sinus](https://gitlab.utc.fr/uav-hds/flair/flair-src/-/tree/main/demos/Sinus).
**NB**: Filter and SensorActuator libraries sources are also a good starting point to see how to program with Flair. Yet, they use the [pimpl idiom](http://c2.com/cgi/wiki?PimplIdiom), which can be harder to read than this example.
# Compilation
There is various ways to compile/recompile it:
*[Compile among everything](build-system/#compile-flair-libraries-tools-and-demos-all-together)(recommended), maybe you have already done it!
*[Recompile only this demo](build-system/#recompile-a-particular-project)
*[Generate and compile it alone](build-system/#compile-your-own-project)
Open a terminal on the target and execute the program through its script:
`# ./Sinus.sh PC_address`
With *PC_address* your PC IP address.
This script, as for ground control station, launches the program with some arguments.
Note that the script also detects if the system uses Xenomai or not, in order to launch the corresponding program version (real time or not).
### setup
When executing the program, the ground control station should construct itself and show setup and graphs for the sinus.
