Change Log
=======

All notable changes to this project will be documented in this file.

The format is based on [Keep a Changelog](http://keepachangelog.com/).

The [milestone](https://egit.irs.uni-stuttgart.de/eive/eive-obsw/milestones)
list yields a list of all related PRs for each release.

Starting at v2.0.0, this project will adhere to semantic versioning and the the following changes
will consitute of a breaking change warranting a new major release:

- The TMTC interface changes in any shape of form.
- The behaviour of the OBSW changes in a major shape or form relevant for operations

# [unreleased]

# [v1.35.0] 2023-03-04

eive-tmtc: v2.16.4

## Added

- Improved the OBSW watchdog by adding a watch functionality. The watch functionality is optional
  and has to be enabled specifically by the application being watched by the watchdog when
  starting the watchdog. If the watch functionality is enabled and the OBSW has not pinged
  the watchdog via the FIFO for 2 minutes, the watchdog will restart the OBSW service via systemd.
  The primary OBSW will only activate the watch functionality if it is the OBSW inside the
  `/usr/bin` directory. This allows debugging the system by leaving flashed or manually copied
  debugging images 2 minutes to start the watchdog without the watch functionality.

## Fixed

- Bumped FSFW: `Countdown` and `Stopwatch` use new monotonic clock API now.
- IMTQ: Various fixes, most notably missing buffer time after starting MGM measurement
  and corrections for actuator commanding.
  PR: https://egit.irs.uni-stuttgart.de/eive/eive-obsw/pulls/430

# [v1.34.0] 2023-03-03

eive-tmtc: v2.16.3

This might include the fix for the race condition where CPU usage jumped to 200 %. The race
condition was traced to the `Countdown` class, more specifically to the `getUptime` function where
the `/proc/uptime` file is read.

## Changed

- The SD card prefix is now set earlier inside the `CoreController` constructor
- The watchdog handling was moved outside the `CoreController` into the main loop.
- Moved polling of all SPI parts to the same PST.
- Allow quicker transition for the EIVE system component by allowing consecutive TCS and ACS
  component commanding again.
- Changed a lot of lock guards to use timeouts
- Queue sizes of TCP/UDP servers increased from 20 to 50
- Significantly simplified and improved lock guard handling in TCS and ACS board polling
  tasks.

## Fixed

- IMTQ: Sets were filled with wrong data, e.g. Raw MTM was filled with calibrated MTM measurements.
- Set RM3100 dataset to valid.
- Fixed units in calculation of ACS control laws safe and detumble.
- Bump FSFW for change in Countdown: Use system clock instead of reading uptime from file
  to prevent possible race condition.
- GPS: No fix considered a fault now after 30 minutes instead of 5 hours.
- SUS Assembly FDIR: Prevent permanent SAFE mode fallbacks by introducing special health
  handling.
  PR: https://egit.irs.uni-stuttgart.de/eive/eive-obsw/pulls/418/files

## Added

- Added Syrlinks Assembly object to allow recovery handling and to fix faulty FDIR behaviour.

# [v1.33.0] 2023-03-01

eive-tmtc: v2.16.2

## Changed

- Move ACS board polling to separate worker thread.
- Move SUS board polling to separate worker thread.

## Fixed

- Linux GPS handler now checks the individual `*_SET` flags when analysing the `gpsd` struct.
  PR: https://egit.irs.uni-stuttgart.de/eive/eive-obsw/pulls/400

# [v1.32.0] 2023-02-24

eive-tmtc: v2.16.1

## Fixed

- ADIS1650X: Added missing MDL_RANG pool entry for configuration set
- Bumped FSFW for bugfix in health service: No execution complete for targeted health announce
  command.
- Removed matrix determinant calculation as part of the `MEKF`, which would take about
  300ms of runtime
- Resetting the `MEKF` now also actually resets its stored state
- Bumped FSFW for bugfix in destination handler: Better error handling and able to process
  destination folder path.

## Changed

- Added basic persistent TM store for PUS telemetry and basic interface to dump and delete
  telemetry. Implementation is based on a timed rotating files, with the addition that files
  might be generated more often if the maximum file size of 8192 bytes is exceeded.
  PR: https://egit.irs.uni-stuttgart.de/eive/eive-obsw/pulls/320/files
- Commented out commanding of actuators as part of the `AcsController`
- Collection sets of the `AcsController` now get updated before running the actual ACS
  algorithm
- `GpsController` now always gets scheduled
- The `CoreController` now initializes the initial clock from the time file as early as possible
  (in the constructor) if possible, which should usually be the case.

## Added

- Added basic persistent TM store for PUS telemetry and basic interface to dump and delete
  telemetry.
  PR: https://egit.irs.uni-stuttgart.de/eive/eive-obsw/pulls/320/files
- `ExecutableComIfDummy` class to have a dummy for classes like the RTD polling class.
- Added `AcsController` action command to confirm solar array deployment, which then deletes
  two files
- Added `AcsController` action command to reset `MEKF`
- `GpsCtrlDummy` now initializes the `gpsSet`
- `RwDummy` now initializes with a non faulty state


# [v1.31.1] 2023-02-23

  PR: https://egit.irs.uni-stuttgart.de/eive/eive-obsw/pulls/402
- ACS Controller: Correction for size of MEKF dataset and some optimization and fixes
  for actuator control which lead to a crash.
  PR: https://egit.irs.uni-stuttgart.de/eive/eive-obsw/pulls/403

# [v1.31.0] 2023-02-23

eive-tmtc: v2.16.0

## Fixed

- Usage of floats as iterators and using them to calculate a uint8_t index in `SusConverter`
- Removed unused variables in the `AcsController`
- Remove shadowing variables inside ACS assembly classes.
  PR: https://egit.irs.uni-stuttgart.de/eive/eive-obsw/issues/385

## Changed

COM PR: https://egit.irs.uni-stuttgart.de/eive/eive-obsw/pulls/364

* Moved transmitter timer and handling of carrier and bitlock event from CCSDS handler to COM
  subsystem
* Added parameter command to be able to change the transmitter timeout
* Solves [#362](https://egit.irs.uni-stuttgart.de/eive/eive-obsw/issues/362)
* Solves [#360](https://egit.irs.uni-stuttgart.de/eive/eive-obsw/issues/360)
* Solves [#361](https://egit.irs.uni-stuttgart.de/eive/eive-obsw/issues/361)
* Solves [#386](https://egit.irs.uni-stuttgart.de/eive/eive-obsw/issues/386)
- All `targetQuat` functions in `Guidance` now return the target quaternion (target
  in ECI frame), which is passed on to `CtrlValData`.
- Moved polling sequence table definitions and source code to `mission/core` folder.
  PR: https://egit.irs.uni-stuttgart.de/eive/eive-obsw/pulls/395

## Added

- `MEKF` now returns an unique returnvalue depending on why the function terminates. These
  returnvalues are used in the `AcsController` to determine on how to procede with its
  perform functions. In case the `MEKF` did terminate before estimating the quaternion
  and rotational rate, an info event will be triggered. Another info event can only be
  triggered after the `MEKF` has run successfully again. If the `AcsController` tries to
  perform any pointing mode and the `MEKF` fails, the `performPointingCtrl` function will
  set the RWs to the last RW speeds and set a zero dipole vector. If the `MEKF` does not
  recover within 5 cycles (2 mins) the `AcsController` triggers another event, resulting in
  the `AcsSubsystem` being commanded to `SAFE`.
- `MekfData` now includes `mekfStatus`
- `CtrlValData` now includes `tgtRotRate`

# [v1.30.0] 2023-02-22

eive-tmtc: v2.14.0

Event IDs for PDEC handler have changed in a breaking manner.

## Added and Fixed

- PDEC: Added basic FDIR to limit the number of allowed TC interrupts and to allow complete task
  lockups in the case an IRQ is immediately re-raised by the PDEC module. This is done by only
  allowing a certain number of handled IRQs (whether they yield a valid TC or not) during
  time windows of one second. Right now, 800 IRQs/TCs are allowed per time window.
  This time window is reset if a TC reception timeout after 500ms occurs. TBD whether the maximum
  allowed number will be a configurable parameter. If the number of occured IRQs is exceeded,
  an event is triggered and the task is delayed for 400 ms.
  PR: https://egit.irs.uni-stuttgart.de/eive/eive-obsw/pulls/393

# [v1.29.1] 2023-02-21

## Fixed

- Limit number of handled messages for core TM handlers:
  - https://egit.irs.uni-stuttgart.de/eive/eive-obsw/issues/391
  - https://egit.irs.uni-stuttgart.de/eive/eive-obsw/issues/390
  - https://egit.irs.uni-stuttgart.de/eive/eive-obsw/issues/389
- HeaterHandler better handling for faulty message reception
  Issue: https://egit.irs.uni-stuttgart.de/eive/eive-obsw/issues/388
- Disable stopwatch in MAX31865 polling task

# [v1.29.0] 2023-02-21

eive-tmtc: v2.13.0

## Changed

- Refactored IMTQ handlers to also perform low level I2C communication tasks in separate thread.
  This avoids the various delays needed for I2C communication with that device inside the ACS PST.
  (e.g. 1 ms delay between each transfer, or 10 ms integration delay for MGM measurements).

## Added

- Added new heater info set for the TCS controller. This set contains the heater switch states
  and the current draw.
  PR: https://egit.irs.uni-stuttgart.de/eive/eive-obsw/pulls/351
- The HeaterHandler now exposes a mode which reflects whether the heater power
  is on or off. It also triggers mode events for its heater children objects
  which show whether the specific heaters are on or off. The heater handler
  will be part of the TCS tree.
  PR: https://egit.irs.uni-stuttgart.de/eive/eive-obsw/pulls/351

# [v1.28.1] 2023-02-21

## Fixed

- Patch version which compiles for EM
- CFDP Funnel bugfix: CCSDS wrapping was buggy and works properly now.
- PDEC: Some adaptions to prevent task lockups on invalid FAR states.
  PR: https://egit.irs.uni-stuttgart.de/eive/eive-obsw/pulls/393
- CMakeLists.txt fix which broke CI/CD builds when server could not retrieve full git SHA.
- Possible regression in the MAX31865 polling task: Using a `ManualCsLockGuard` for reconfiguring
  and then polling the sensor is problematic, invalid sensor values will be read.
  CS probably needs to be de-asserted or some other HW/SPI specific issue. Letting the SPI ComIF
  do the locking does the job.

## Changed

- Add `-Wshadow=local` shadowing warnings and fixed all of them
- Updated generated CSV files: Support for skip directive and explicit
  "No description" info string
- The polling threads for actuator polling now have a slightly higher priority than the ACS PST
  to ensure timing requirements are met.

## Added

- git post checkout hook which initializes and updates the submodules
  automatically.

# [v1.28.0] 2023-02-17

eive-tmtc: v2.12.7

## Added

- In case the ACS Controller does recognize more than one RW to be invalid and therefore not
  available, it does not perform pointing control but aborts shortly after `sensorProcessing`. If the
  problem persits for 5 ACS cycles, the `MULTIPLE_RW_INVALID` event is triggered, which invokes the
  transition of the `AcsSubsystem` to safe mode.

## Changed

- Igrf13 model vector now outputs as uT instead of nT
- Changed timings for `AcsPst`, more time for sun sensors.
- Added values for MGM sensor fusion
- Refactored RW Software: Polling runs in separate thread, all RWs are now polled in under 60 ms.
  PR: https://egit.irs.uni-stuttgart.de/eive/eive-obsw/pulls/381
- Bumped FSFW to allow initializing child modes in `SubsystemBase` derived objects.

## Fixed

- Fixed values for GYR sensor fusion
- Fixed speed types for `rwHandlingParameter`
- Pseudo inverse used for allocating torque to RWs and RW antistiction now actually consider the
  state of the RWs

# [v1.27.2] 2023-02-14

Reaction Wheel handling was determined to be (quasi) broken and needs to be fixed in future release
to be usable by ACS controller.

eive-tmtc: v2.12.6

## Added

- Function for the ACS controller to command MTQ and RWs called by all subroutines
- RwHandler now handles commanding of RW speeds via RwSpeedActuationSet
- Tracing supports which allows checking whether threads are running as usual.

## Changed

- Remove 2 TCS threads.
- Move low level polling into ACS PST, move high level device handlers into TCS system task.
- ActCmds now returns command vectors as integers as required by the actuators
  and scales them to the appropriate range
- All RwHandler are now polled five times per ACS cycle
- Remove 2 TCS threads. Move low level polling into ACS PST, move high level device handlers into
  TCS system task.
- Further reduce number of threads:
  1. Remove PUS low priority task, move assigned threads to the generic system task
  2. Group events and verification tasks into PUS high priority task
  3. Group all other components into PUS medium priority task
  4. Add SCEX device handler to PL task, remove dedicated thread

## Removed

- lwgps dependency not compiled anymore, is not used

# [v1.27.1] 2023-02-13

## Fixed

- Fix for SPI ComIF: Set transfer size to 0 for failed transfers
- Fix shadowing issue with locks in MAX31865 low level handler

# [v1.27.0] 2023-02-13

eive-tmtc: v2.12.5

Added EIVE system top mode component. Currently, only SAFE and IDLE mode are
implemented, and the system does not do more than commanding TCS and ACS
into the correct modes. It does not have a lot of mode tracking capabilities
yet because the ACS controller might alternate between SAFE and DETUMBLE.
It takes around 5-10 seconds for the EIVE system to reach the SAFE mode.

The new system is used at software boot to command the satellite into safe mode
on each reboot. This behaviour can be disabled with the
`OBSW_SWITCH_TO_NORMAL_MODE_AFTER_STARTUP` flag.

## Added

- New EIVE system component like explained above.

## Changed

- The satellite now commands itself into SAFE mode on each reboot, which
  triggers a lot of events on each SW reboot. The TCS subsystem will commanded
  to NORMAL mode immediately while the ACS subsystem will be commanded to
  SAFE mode. The payload subsystem will be commanded OFF.
- `RELEASE_BUILD` flag moved to `commonConfig.h`
- The ACS subsystem transitions are now staggered: The SUS board assembly
  is commanded as a separate transition. This reduces the risk of long bus lockups.
- No INFO mode event translations for release builds to reduce number of
  printouts.
- More granular locking inside the MAX31865 low level read handler.

## Fixed

- More DHB thermal module fixes.
- ACS PST frequency extended to 0.8 seconds in debug builds to avoid SPI
  bus lockups.
- Local datapool fixes for the `PlocSupervisorHandler`

# [v1.26.4] 2023-02-10

eive-tmtc: v2.12.3

## Fixed

- `SdCardManager.cpp` `isSdCardUsable`: Use `ext4` instead of `vfat` to check read-only state.

# [v1.26.3] 2023-02-09

eive-tmtc: v2.12.2

## Added

- First version of a TCS controller heater control loop, but
  the loop is disabled for now.

## Changed

- Reworked dummy handling for the TCS controller.
  PR: https://egit.irs.uni-stuttgart.de/eive/eive-obsw/pulls/325
- Generator scripts now generate files for hosted and for Q7S build.

## Fixed

- GPS Controller: Set fix value to 0 when switching off to allow
  `GPS_FIX_CHANGE` to work when switching the GPS back on.

# [v1.26.2] 2023-02-08

## Changed

- ACS Controller scheduling is now configurable via the `eive/definitions.h` file. Also ensured
  that scheduling is done in big blocks to reduce risk of missed deadlines.
- Replaced chained locks for polling new sensor data to the `AcsController`.
- Made TM store even larger.

## Fixed

- Bugfix for PDEC handler which causes the PIR register of the PDEC to never
  be cleared on release builds. The dummy variable used to read the register
  needs to be declared volatile to avoid compiler optimizations.
  PR: https://egit.irs.uni-stuttgart.de/eive/eive-obsw/pulls/374
- Bumped FSFW for fix of possible memory leaks in TCP/IP TMTC bridge
  inside the FSFW.

## Added

- Create TCS controller for EM build.

# [v1.26.1] 2023-02-08

- Initialize parameter helper in ACS controller.

# [v1.26.0] 2023-02-08

  is only used to retrieve the git SHA hash now. Also removed `OBSWVersion.h` accordingly.
- Build system: Fixed small bug, where the version itself was
  stored as the git SHA hash in `commonConfig.h`. This will be
  an empty string now for regular versions.
- Bump FSFW for important fix in PUS mode service.

### ACS

- Bugfixes in 'SensorProcessing' where previously MGM values would be calibrated before being
  transformed in body RF. However, the calibration values are in the body RF. Also fixed the
  validity flag of 'mgmVecTotDerivative'.

eive-tmtc version: v2.12.0

## Changed

- Updated Subsystem mode IDs to avoid clashes with regular device handler modes.

## Fixed

- `GpsHyperionLinuxController`: Fix `gpsd` polling by continuously calling `gps_read` in one cycle
  until it does not have any data left anymore. Also, the data is now polled in a permanent loop,
  where controller handling is done on 0.2 second timeouts.
  PR: https://egit.irs.uni-stuttgart.de/eive/eive-obsw/pulls/368

# [v1.24.0] 2023-02-03

- eive-tmtc v2.10.0
- `AcsSubsystem`: OFF, SAFE and DETUMBLE mode were tested. Auto-transitions SAFE <-> DETUMBLE tested
  as well. Other modes still need to be tested.

## Fixed

- `AcsController`: Parameter fix in `DetumbleParameter`.
- Set GPS set entries to invalid on MODE_OFF command.
- Bump FSFW for bugfix in `setNormalDatapoolEntriesInvalid` where the validity was not set to false
  properly
- Fixed usage of uint instead of int for commanding MTQ. Also fixed the range in which the ACS Ctrl
  commands the MTQ to match the actual commanding range.
  PR: https://egit.irs.uni-stuttgart.de/eive/eive-obsw/pulls/363
- Regression: Revert swap of SUS0 and SUS6. Those devices are on separate power lines. In a
  future fix, the calibration matrices of SUS0 and SUS6 will be swapped.

## Changed

- Update ACS scheduling to represent the actual ACS design. There is one ACS PST now for all
  timing sensitive ACS operations. In the debug builds, the new ACS polling sequence table
  will have a period of 0.6 seconds, but will remain 0.4 seconds for the release build.
  PR: https://egit.irs.uni-stuttgart.de/eive/eive-obsw/pulls/365
- `ACS::SensorValues` is now an ACS controller member to reduce the risk of stack overflow.

TMTC rev: 15adb9bf2ec68304a4f87b8dd418c1a8353283a3

## Fixed

- Bugfix in FSFW where the sequence flags of the PUS packets were set to continuation segment (0b00)
  instead of unsegmented (0b11).
- Bugfix in FSFW where the MGM RM3100 value Z axis data was parse incorrectly.
  PR: https://egit.irs.uni-stuttgart.de/eive/fsfw/pulls/123

## Fixed

- Bumped FSFW to include fixes in the time service.
  PR: https://egit.irs.uni-stuttgart.de/fsfw/fsfw/pulls/726
- The CCSDS handler starts the transmitter timer each time it is commanded to MODE_ON and times
  out the timer when the handler is commanded to MODE_OFF
- If the timer is timed out the CCSDS handler will disable the TX clock which will cause the
  syrlinks to got to standby mode
- PDEC handler now parses the FAR register also in interrupt mode


# [v1.22.1] 2023-01-30

## Changed

- Updated FSFW to include addition where the `SO_REUSEADDR` option is set
  on the TCP server, which should improve its ergonomics.

# [v1.22.0] 2023-01-28

TMTC version: v2.6.1

## Added

- First COM subsystem implementation. It mirrors the Syrlinks mode/submodes but also takes
  care of commanding the CCSDS handler. It expects the Syrlinks submodes as mode commands.
  PR: https://egit.irs.uni-stuttgart.de/eive/eive-obsw/pulls/358
- The CCSDS handler has has a new submode (3) to configure the default datarate.
- Default datarate parameter commanding moved to COM subsystem.

- MGM4 handling in ACS sensor processing: Bugfix in `mulScalar` operation
  PR: https://egit.irs.uni-stuttgart.de/eive/eive-obsw/pulls/354
- Subsystem ID clash: CORE subsystem ID was the same as Syrlinks subsystem ID.

## Changed

- Startracker temperature set and PCDU switcher set are diagnostic now
- `SyrlinksHkHandler` renamed to `SyrlinksHandler` to better reflect that it does more than
  just HK and is also responsible for setting the TX mode of the device.
- `SyrlinksHandler`: Go to startup immediately because the Syrlinks device should always be on
  by default.
- `SyrlinksHandler`: Go to normal mode at startup.

## Added

- The Syrlinks handler has submodes for the TX mode now: RX Only (0), RX and TX default
  datarate (1), RX and TX Low Rate (2), RX and TX High Rate (3) and TX Carrier Wave (4).
  The submodes apply for both ON and NORMAL mode. The default datarate can be updated using
  a parameter command (domain ID 0 and unique ID 0) with value 0 for low rate and 1 for high rate.
- The Syrlinks handler always sets TX to standby when switching off
- The Syrlinks handler triggers a new TX_ON event when the transmitter was switched on successfully
  and a TX_OFF event when it was switched off successfully.
- Startracker temperature set and PCDU switcher set are diagnostic now
- The CCSDS handler can accept mode commands now. It accepts ON and OFF commands. Furthermore
  it has a submode for low datarate (1) and high datarate (2) for the ON command.

# [v1.20.0] 2023-01-24

## Added

- The Q7S SW now checks for a file named `boot_delay_secs.txt` in the home directory.
  If it exists and the file is empty, it will delay for 6 seconds before continuing
  with the regular boot. It can also try to read delay seconds from the file.
  PR: https://egit.irs.uni-stuttgart.de/eive/eive-obsw/pulls/340.
- Basic TCS Subsystem component.

  PR: https://egit.irs.uni-stuttgart.de/eive/eive-obsw/pulls/319
- The ACS Controller Gyro Sets (raw and processed) and the MEKF dataset are diagnostics now.
- Bumped FSFW for Service 11 improvement which includes size and CRC check for contained TC
- Syrlinks module now always included for both EM and FM
- SA Deployment: Allow specifying the switch interval and the initial channel. This allows testing
  the new deployment procedure where each channel is burned for half of the whole burn duration.
  It also allows burning only one channel for the whole burn duration. The autonomous mechanism
  was adapted to burn each channel for half of the burn time by default.

  TMTC PR: https://egit.irs.uni-stuttgart.de/eive/eive-tmtc/pulls/127
- `Max31865RtdLowlevelHandler.cpp`: For each RTD device, the config is now re-written before
  every read. This seems to fix some issue with invalid temperature sensor readings.
  PR: https://egit.irs.uni-stuttgart.de/eive/eive-obsw/pulls/345

## Fixed

- `GyroADIS1650XHandler`: Updated handler to determine correct dynamic range from `RANG_MDL`
  register readout. This is because ADIS16505-3BMLZ devices are used on the ACS board and the
  previous range setting was wrong. Also fixed a small error properly set internal state
  on shut-down.

### EM and FM splitup & Build Workflow improvements

PR: https://egit.irs.uni-stuttgart.de/eive/eive-obsw/pulls/238

- Split up `bsp_q7s` in separate EM and FM build with module loading set to different
  default values. The EM object factory is unique which allows building a parallel setup
  with dummy components
- All major BSPs have an own `OBSWConfig.h.in` file which simplifies the file significantly
- Renamed Q7S primary build folders:
  - `cmake-build-debug-q7s` for primary development build
  - `cmake-build-release-q7s` for primary release build
  - `cmake-build-debug-q7s-em` for primary development build of the EM software
  - `cmake-build-release-q7s-em` for primary release build of the EM software
- Refactored Q7S helper script handling. It is now intended and preferred to copy the environment
  script to the same folder level as the `eive-obsw` and source it. This will also
  add the path containing the shell helper scripts to `PATH`
- The actual helper shell scripts were renamed as well to `q7s-<buildSystem>-<buildType>.sh`
