Therefore, a mode and health system provides control over the states of the software and the controlled devices.
In addition, a simple mechanism of event based fault detection, isolation and recovery is implemented as well.
The recommended hardware is a microprocessor with more than 2 MB of RAM and 1 MB of non-volatile Memory.
The recommended hardware is a microprocessor with more than 1 MB of RAM and 1 MB of non-volatile Memory.
For reference, current Applications use a Cobham Gaisler UT699 (LEON3FT), a ISISPACE IOBC or a Zynq-7020 SoC.
The `fsfw` was also tested on the STM32H743ZI-Nucleo board.
## Structure

If Space Packets are used, a timestamper must be created.
An example can be found in the timemanager folder, this uses CCSDSTime::CDS_short.
#### DeviceHandling
#### Device Handlers
DeviceHandlers are a core component of the FSFW.
The idea is, to have a software counterpart of every physical device to provide a simple mode, health and commanding interface.
By separating the underlying Communication Interface with DeviceCommunicationIF, a DH can be tested on different hardware.
The DH has mechanisms to monitor the communication with the physical device which allow for FDIR reaction.
Device Handlers can be created by overriding `DeviceHandlerBase`.
A standard FDIR component for the DH will be created automatically but can be overwritten by the user.

## Example config
A example config can be found in defaultcfg/fsfwconfig.
A example config can be found in defaultcfg/fsfwconfig. The fsfw will require certain configuration files,
so a configuration folder should be provided and the folder should be added to the include path.
