Detailed Description

PT Calibration Manager.

Loads and manages PT calibration coefficients from JSON or CSV files. Provides calibrated pressure values for sensor channels.

◆ calculate_pressure()

double fsw::calibration::PTCalibrationManager::calculate_pressure	(	uint8_t	channel_id,
		int32_t	adc_code ) const

Calculate calibrated pressure for a channel.

Parameters

channel_id	Sensor channel ID
adc_code	Raw ADC code

Returns: Calibrated pressure in PSI, or 0.0 if not calibrated

Definition at line 313 of file PTCalibration.cpp.

References get_calibration(), and p.

Referenced by invert_abort_psi_to_adc(), and main().

◆ clear_calibration()

void fsw::calibration::PTCalibrationManager::clear_calibration ( uint8_t channel_id )

Remove any cubic for a logical channel, so is_calibrated() returns false again.

Used by the calibration service's "clear" so a cleared/uncalibrated cubic sensor streams nothing (0) rather than reverting to a factory/baseline curve.

◆ get_calibrated_count()

size_t fsw::calibration::PTCalibrationManager::get_calibrated_count ( ) const

inline

Get number of calibrated channels.

◆ get_calibration()

const PTCalibrationCoeffs * fsw::calibration::PTCalibrationManager::get_calibration ( uint8_t channel_id ) const

Get calibration coefficients for a sensor channel.

Parameters

channel_id Sensor channel ID (1-indexed)

Returns: Calibration coefficients if available, nullptr otherwise

◆ is_calibrated()

bool fsw::calibration::PTCalibrationManager::is_calibrated ( uint8_t channel_id ) const

Check if a channel has calibration.

Parameters

channel_id Sensor channel ID

Returns: true if calibrated

Definition at line 301 of file PTCalibration.cpp.

Referenced by invert_abort_psi_to_adc(), and main().

◆ load_calibration()

bool fsw::calibration::PTCalibrationManager::load_calibration ( )

Auto-load calibration from default paths Default: factory CSV first, then newest GUI JSON overlays every channel it lists (fixes CSV PT6≠GN2 ch6).

CAL_PT_JSON_MISSING_ONLY=1 — JSON only fills gaps (legacy). CAL_PT_JSON_FIRST=1 — JSON only, then CSV.

Returns: true if any calibration was loaded

◆ load_from_csv()

bool fsw::calibration::PTCalibrationManager::load_from_csv ( const std::string & csv_path )

Load calibration from CSV file (from DiabloAvionics).

Parameters

csv_path Path to CSV calibration file

Returns: true if loaded successfully

Definition at line 212 of file PTCalibration.cpp.

◆ load_from_json()

bool fsw::calibration::PTCalibrationManager::load_from_json	(	const std::string &	json_path,
		bool	merge_missing_only = false )

Load calibration from JSON file (from calibration GUI).

Parameters

json_path	Path to JSON calibration file
merge_missing_only	If true, only add channels not already present after CSV; if false, every channel in JSON overwrites the same logical key (GUI per-connector calibration).

Returns: true if at least one channel was loaded/merged

◆ set_calibration()

void fsw::calibration::PTCalibrationManager::set_calibration	(	uint8_t	channel_id,
		const PTCalibrationCoeffs &	coeffs )

Set/replace the cubic coefficients for a logical channel at runtime.

Used by the calibration service when an operator builds a cubic live from captured reference points — the new fit takes effect immediately on the streaming path (which evaluates these coefficients per packet).

Parameters

channel_id is the logical calibration channel (pt_logical_calibration_channel), not a board-local connector.

◆ set_default_paths()

void fsw::calibration::PTCalibrationManager::set_default_paths	(	const std::string &	json_dir,
		const std::string &	csv_path )

static

Set default calibration file paths.
