# <a id="top"></a> <a name="linux"></a> FSFW Example Application

This repository features a demo application. The example has been run successfully on the following 
platforms:

 - Linux host machine with the Linux OSAL or the Host OSAL
 - Windows with the Host OSAL
 - STM32H743ZI-Nucleo with the FreeRTOS OSAL
 - Raspberry Pi with the Linux OSAL
 - STM32H743ZI-Nucleo with the RTEMS OSAL

The purpose of this example is to provide a demo of the FSFW capabilities.
However, it can also be used as a starting point to set up a repository for
new flight software. It also aims to provide developers with practical examples
of how the FSFW is inteded to be used and how project using the FSFW should or can be
set up and it might serve as a basic test platform for the FSFW as well to ensure all OSALs
are compiling and running as expected.

The repository contains a Python TMTC program which can be used to showcase
the TMTC capabilities of the FSFW (currently, using the ECSS PUS packet standard).

# Configuring the Example

The build system will copy three configuration files into the build directory:

1. `commonConfig.h` which contains common configuration parameters
2. `OBSWConfig.h` which can contain machine and architecture specific configuration options
3. `FSFWConfig.h` which contains the configuration for the flight software framework

These files can be edited manually after `CMake` build generation.

# Linux - Enabling RTOS functionalities

The last chapter in the [Linux README](https://egit.irs.uni-stuttgart.de/fsfw/fsfw-example-linux-mcu)
specifies some steps required to cleanly run the FSFW on a (host) Linux system if
real time functionalities are turned on via `FSFWConfig.h`.

# Setting up Eclipse for CMake projects

The separate [Eclipse README](https://egit.irs.uni-stuttgart.de/fsfw/fsfw-example-common/src/branch/master/doc/README-eclipse.md) specifies how to set up Eclipse to build CMake
projects. Separate project files and launch configurations for the MinGW build were provided.
The debug output is colored by default. It is recommended to install the
`ANSI Escape in Console` plugin in Eclipse so the coloring works in the Eclipse console. On Windows,
it is recommended to run the applicaton with the Windows command line for the printout to work
properly. You can do this by simply double-clicking the binary or using `start <Exe>` in the
Windows command line
