## Changes from ASTP 0.0.1 to 1.0.0
### Host OSAL
- Bugfix in MessageQueue, which caused the sender not to be set properly
### FreeRTOS OSAL
- vRequestContextSwitchFromISR is declared extern "C" so it can be defined in
a C file without issues
### PUS Services
- It is now possible to change the message queue depth for the telecommand verification service (PUS1)
- The same is possible for the event reporting service (PUS5)
- PUS Health Service added, which allows to command and retrieve health via PUS packets
### EnhancedControllerBase
- New base class for a controller which also implements HasActionsIF and HasLocalDataPoolIF
### Local Pool
- Interface of LocalPools has changed. LocalPool is not a template anymore. Instead the size and
bucket number of the pools per page and the number of pages are passed to the ctor instead of
two ctor arguments and a template parameter
### Parameter Service
- The API of the parameter service has been changed to prevent inconsistencies
between documentation and actual code and to clarify usage.
- The parameter ID now consists of:
1. Domain ID (1 byte)
2. Unique Identifier (1 byte)
3. Linear Index (2 bytes)
The linear index can be used for arrays as well as matrices.
The parameter load command now explicitely expects the ECSS PTC and PFC
information as well as the rows and column number. Rows and column will
default to one, which is equivalent to one scalar parameter (the most
important use-case)
### File System Interface
- A new interfaces specifies the functions for a software object which exposes the file system of
a given hardware to use message based file handling (e.g. PUS commanding)
### Internal Error Reporter
- The new internal error reporter uses the local data pools. The pool IDs for
the exisiting three error values and the new error set will be hardcoded for
now, the the constructor for the internal error reporter just takes an object
ID for now.
### Device Handler Base
- There is an additional `PERFORM_OPERATION` step for the device handler base. It is important
that DHB users adapt their polling sequence tables to perform this step. This steps allows for
a clear distinction between operation and communication steps
- setNormalDatapoolEntriesInvalid is not an abstract method and a default implementation was provided
- getTransitionDelayMs is now an abstract method
### DeviceHandlerIF
- Typo for UNKNOWN_DEVICE_REPLY
### Events
- makeEvent function: Now takes three input parameters instead of two and
allows setting a unique ID. Event.cpp source file removed, functions now
defined in header directly. Namespaces renamed. Functions declared `constexpr`
now
### Commanding Service Base
- CSB uses the new fsfwconfig::FSFW_CSB_FIFO_DEPTH variable to determine the FIFO depth for each
CSB instance. This variable has to be set in the FSFWConfig.h file
### Service Interface
- Proper printf support contained in ServiceInterfacePrinter.h
- CPP ostream support now optional (can reduce executable size by 150 - 250 kB)
- Amalagated header which determines automatically which service interface to use depending on FSFWConfig.h configuration.
Users can just use #include <fsfw/serviceinterface/ServiceInterface.h>
- If CPP streams are excluded, sif:: calls won't work anymore and need to be replaced by their printf counterparts.
For the fsfw, this can be done by checking the processor define FSFW_CPP_OSTREAM_ENABLED from FSFWConfig.h.
For mission code, developers need to replace sif:: calls by the printf counterparts, but only if the CPP stream are excluded.
If this is not the case, everything should work as usual.
### ActionHelper and ActionMessage
- ActionHelper finish function and ActionMessage::setCompletionReply now expects explicit
information whether to report a success or failure message instead of deriving it implicitely
from returnvalue
### PUS Parameter Service 20
Added PUS parameter service 20 (only custom subservices available).

# Flight Software Framework (FSFW)
The Flight Software Framework is a C++ Object Oriented Framework for unmanned,
@ -8,152 +9,40 @@ The initial version of the Flight Software Framework was developed during
the Flying Laptop Project by the University of Stuttgart in cooperation
with Airbus Defence and Space GmbH.
## Intended Use
## Quick facts
The framework is designed for systems, which communicate with external devices, perform control loops, receive telecommands and send telemetry, and need to maintain a high level of availability.
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 framework is designed for systems, which communicate with external devices, perform control loops, receive telecommands and send telemetry, and need to maintain a high level of availability. 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.
For reference, current Applications use a Cobham Gaisler UT699 (LEON3FT), a ISISPACE IOBC or a Zynq-7020 SoC.
The FSFW provides abstraction layers for operating systems to provide a uniform operating system abstraction layer (OSAL). Some components of this OSAL are required internally by the FSFW but is also very useful for developers to implement the same application logic on different operating systems with a uniform interface.
Currently, the FSFW provides the following OSALs:
- Linux
- Host
- FreeRTOS
- RTEMS
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 successfully run on the STM32H743ZI-Nucleo board and on a Raspberry Pi and is currently running on the active satellite mission Flying Laptop.
## Getting started
The [FSFW example](https://egit.irs.uni-stuttgart.de/fsfw/fsfw_example) provides a good starting point and a demo to see the FSFW capabilities and build it with the Make or the CMake build system. It is recommended to evaluate the FSFW by building and playing around with the demo application.
Generally, the FSFW is included in a project by compiling the FSFW sources and providing
a configuration folder and adding it to the include path. There are some functions like `printChar` which are different depending on the target architecture and need to be implemented by the mission developer.
A template configuration folder was provided and can be copied into the project root to have
a starting point. The [configuration section](doc/README-config.md#top) provides more specific information about the possible options.

## Structure
The general structure is driven by the usage of interfaces provided by objects. The FSFW uses C++11 as baseline. The intention behind this is that this C++ Standard should be widely available, even with older compilers.
The FSFW uses dynamic allocation during the initialization but provides static containers during runtime.
This simplifies the instantiation of objects and allows the usage of some standard containers.
Dynamic Allocation after initialization is discouraged and different solutions are provided in the FSFW to achieve that.
The fsfw uses Run-time type information.
Exceptions are not allowed.
### Failure Handling
Functions should return a defined ReturnValue_t to signal to the caller that something is gone wrong.
Returnvalues must be unique. For this the function HasReturnvaluesIF::makeReturnCode or the Macro MAKE_RETURN can be used.
The CLASS_ID is a unique id for that type of object. See returnvalues/FwClassIds.
### OSAL
The FSFW provides operation system abstraction layers for Linux, FreeRTOS and RTEMS. A independent OSAL called "host" is currently not finished. This aims to be running on windows as well.
The OSAL provides periodic tasks, message queues, clocks and Semaphores as well as Mutexes.
### Core Components
Clock:
* This is a class of static functions that can be used at anytime
* Leap Seconds must be set if any time conversions from UTC to other times is used
ObjectManager (must be created):
* The component which handles all references. All SystemObjects register at this component.
* Any SystemObject needs to have a unique ObjectId. Those can be managed like objects::framework_objects.
* A reference to an object can be get by calling the following function. T must be the specific Interface you want to call.
A nullptr check of the returning Pointer must be done. This function is based on Run-time type information.
``` c++
template <typename T> T* ObjectManagerIF::get( object_id_t id )
```
* A typical way to create all objects on startup is a handing a static produce function to the ObjectManager on creation.
By calling objectManager->initialize() the produce function will be called and all SystemObjects will be initialized afterwards.
Event Manager:
* Component which allows routing of events
* Other objects can subscribe to specific events, ranges of events or all events of an object.
* Subscriptions can be done during runtime but should be done during initialization
* Amounts of allowed subscriptions must be configured by setting this parameters:
``` c++
namespace fsfwconfig {
//! Configure the allocated pool sizes for the event manager.
static constexpr size_t FSFW_EVENTMGMR_MATCHTREE_NODES = 240;
static constexpr size_t FSFW_EVENTMGMT_EVENTIDMATCHERS = 120;
static constexpr size_t FSFW_EVENTMGMR_RANGEMATCHERS = 120;
}
```
Health Table:
* A component which holds every health state
* Provides a thread safe way to access all health states without the need of message exchanges
Stores
* The message based communication can only exchange a few bytes of information inside the message itself. Therefore, additional information can be exchanged with Stores. With this, only the store address must be exchanged in the message.
* Internally, the FSFW uses an IPC Store to exchange data between processes. For incoming TCs a TC Store is used. For outgoing TM a TM store is used.
* All of them should use the Thread Safe Class storagemanager/PoolManager
Tasks
There are two different types of tasks:
* The PeriodicTask just executes objects that are of type ExecutableObjectIF in the order of the insertion to the Tasks.
* FixedTimeslotTask executes a list of calls in the order of the given list. This is intended for DeviceHandlers, where polling should be in a defined order. An example can be found in defaultcfg/fsfwconfig/pollingSequence
### Static Ids in the framework
Some parts of the framework use a static routing address for communication.
An example setup of ids can be found in the example config in "defaultcft/fsfwconfig/objects/Factory::setStaticFrameworkObjectIds()".
### Events
Events are tied to objects. EventIds can be generated by calling the Macro MAKE_EVENT. This works analog to the returnvalues.
Every object that needs own EventIds has to get a unique SUBSYSTEM_ID.
Every SystemObject can call triggerEvent from the parent class.
Therefore, event messages contain the specific EventId and the objectId of the object that has triggered.
### Internal Communication
Components communicate mostly over Message through Queues.
Those queues are created by calling the singleton QueueFactory::instance()->create().
### External Communication
The external communication with the mission control system is mostly up to the user implementation.
The FSFW provides PUS Services which can be used to but don't need to be used.
The services can be seen as a conversion from a TC to a message based communication and back.
#### CCSDS Frames, CCSDS Space Packets and PUS
If the communication is based on CCSDS Frames and Space Packets, several classes can be used to distributed the packets to the corresponding services. Those can be found in tcdistribution.
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
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.
A standard FDIR component for the DH will be created automatically but can be overwritten by the user.
#### Modes, Health
The two interfaces HasModesIF and HasHealthIF provide access for commanding and monitoring of components.
On-board Mode Management is implement in hierarchy system.
DeviceHandlers and Controllers are the lowest part of the hierarchy.
The next layer are Assemblies. Those assemblies act as a component which handle redundancies of handlers.
Assemblies share a common core with the next level which are the Subsystems.
Those Assemblies are intended to act as auto-generated components from a database which describes the subsystem modes.
The definitions contain transition and target tables which contain the DH, Assembly and Controller Modes to be commanded.
Transition tables contain as many steps as needed to reach the mode from any other mode, e.g. a switch into any higher AOCS mode might first turn on the sensors, than the actuators and the controller as last component.
The target table is used to describe the state that is checked continuously by the subsystem.
All of this allows System Modes to be generated as Subsystem object as well from the same database.
This System contains list of subsystem modes in the transition and target tables.
Therefore, it allows a modular system to create system modes and easy commanding of those, because only the highest components must be commanded.
The health state represents if the component is able to perform its tasks.
This can be used to signal the system to avoid using this component instead of a redundant one.
The on-board FDIR uses the health state for isolation and recovery.
## Example config
A example config can be found in defaultcfg/fsfwconfig.
## Unit Tests
Unit Tests are provided in the unittest folder. Those use the catch2 framework but do not include catch2 itself.
See README.md in the unittest Folder.

* @brief The DataSetBase class manages a set of locally checked out variables.
* @details
* This class manages a list, where a set of local variables (or pool variables)
* are registered. They are checked-out (i.e. their values are looked
* up and copied) with the read call. After the user finishes working with the
* pool variables, he can write back all variable values to the pool with
* the commit call. The data set manages locking and freeing the data pool,
* to ensure that all values are read and written back at once.
*
* An internal state manages usage of this class. Variables may only be
* registered before the read call is made, and the commit call only
* after the read call.
*
* If pool variables are writable and not committed until destruction
* of the set, the DataSet class automatically sets the valid flag in the
* data pool to invalid (without) changing the variable's value.
*
* The base class lockDataPool und unlockDataPool implementation are empty
* and should be implemented to protect the underlying pool type.

* The actual data pool structure is a member of this class. Any class which
* has a local data pool shall have this manager class as a member and implement
* the HasLocalDataPoolIF.
*
* The manager offers some adaption points and functions which can be used
* by the owning class to simplify data handling significantly.
*
* Please ensure that both initialize and initializeAfterTaskCreation are
* called at some point by the owning class in the respective functions of the
* same name!
*
* Users of the data pool use the helper classes LocalDataSet,
* LocalPoolVariable and LocalPoolVector to access pool entries in
* a thread-safe and efficient way.
*
* The local data pools employ a blackboard logic: Only the most recent
* value is stored. The helper classes offer a read() and commit() interface
* through the PoolVariableIF which is used to read and update values.
* Each pool entry has a valid state too.

* Extends the PoolDataSetBase class for local data pools by introducing
* a validity state, a flag to mark the set as changed, and various other
* functions to make it usable by the LocalDataPoolManager class.
*
* This class manages a list, where a set of local variables (or pool variables)
* are registered. They are checked-out (i.e. their values are looked
* up and copied) with the read call. After the user finishes working with the
* pool variables, he can write back all variable values to the pool with
* the commit call. The data set manages locking and freeing the local data
* pools, to ensure thread-safety.
*
* Pool variables can be added to the dataset by using the constructor
* argument of the pool variable or using the #registerVariable member function.
*
* An internal state manages usage of this class. Variables may only be
* registered before any read call is made, and the commit call can only happen
* after the read call.
*
* If pool variables are writable and not committed until destruction
* of the set, the DataSet class automatically sets the valid flag in the
* data pool to invalid (without) changing the variable's value.

* There are two template parameters:
* @tparam T
* This template parameter specifies the data type of an array entry. Currently,
* all plain data types are supported, but in principle any type is possible.
* @tparam vector_size
* This template parameter specifies the vector size of this entry. Using a
