Enumeration Type Documentation

LcModel

enum class anonymous_namespace{calibration_main.cpp}::LcModel

strong

Which model an LC streams: a straight-line fit through the operator's captured points, a cubic fit through them, or the datasheet physics conversion (sensitivity/PGA-gain formula).

No robust/blend — load cells don't need drift-learning. Chosen per sensor from [calibration_model_<lc_board>] in config; absent from the map means Linear (see lc_model_for).

Why linear is the default: a load cell is linear to a few hundredths of a percent, and its zero drifts. A tare is taken as an ADC code and evaluated through the live curve, so on a line it cancels a pure zero shift exactly, wherever the zero has wandered. A cubic fitted over 400-500k and evaluated at a 200k zero extrapolates a full span past its data and bends, so the same tare leaves a load-dependent error. Until a linear sensor has two captured points it streams physics — exactly what an unconfigured LC streamed before this model existed — so a rig with no LC captures reads the same as before.

PtModel

enum class anonymous_namespace{calibration_main.cpp}::PtModel

strong

Which model a PT streams: operator/factory cubic, the robust learner, the 75/25 blend, or the datasheet physics conversion (ratiometric for 0-5 V boards, 4-20 mA for current-loop).

Chosen per sensor from [calibration_model_<board>] in config.toml (see main); a CAL_USE_* env var, when set, overrides all LP sensors via g_env_override.

g_env_override

std::optional<PtModel> anonymous_namespace{calibration_main.cpp}::g_env_override

Set once at startup: when a CAL_USE_* PT env var is present it forces every sensor, else nullopt and the per-sensor config governs.

g_hp_ma_live

std::map<uint8_t, std::array<uint8_t, 11> > anonymous_namespace{calibration_main.cpp}::g_hp_ma_live

Hysteresis: 0 = treat as below loop, 1 = in 4–20 mA band (stops 3.99↔4.01 PSI chatter).

Keyed by board slot so one board's channel going live cannot unlatch another board's same-numbered channel.

g_lc_board_ids

std::set<uint8_t> anonymous_namespace{calibration_main.cpp}::g_lc_board_ids

Board ids of every LC board, so a connector outside active_connectors still routes as LC.

g_lc_full_scale

std::unordered_map<uint16_t, double> anonymous_namespace{calibration_main.cpp}::g_lc_full_scale

Per-sensor LC physics-mode parameters (from [calibration_full_scale_*] / [calibration_sensitivity_*] / [calibration_pga_*], falling back to [calibration.lc] globals).

Only present for uids the config/board provides.

g_lc_model

std::unordered_map<uint16_t, LcModel> anonymous_namespace{calibration_main.cpp}::g_lc_model

uid -> LC streaming model.

A uid absent from this map defaults to Linear (see lc_model_for).

g_lc_uids

std::set<uint16_t> anonymous_namespace{calibration_main.cpp}::g_lc_uids

Every LC uid, populated at startup — the discriminant apply_capture/apply_clear/ reload_live_store use to route a shared uid-keyed cubic_store entry to lc_calibration instead of pt_calibration/robust_manager (PT and LC uids share the store; their board_id ranges never collide, but nothing else tags which kind a uid is).

g_pt_full_scale

std::unordered_map<uint16_t, double> anonymous_namespace{calibration_main.cpp}::g_pt_full_scale

Per-sensor physics-mode parameters (from [calibration_full_scale_*] / [calibration_sense_resistor_*], falling back to the board defaults).

full_scale is PSI at full ADC / at 20 mA; sense_resistor Ω is the 4-20 mA shunt. Only present for uids the config/board provides.

g_pt_model

std::unordered_map<uint16_t, PtModel> anonymous_namespace{calibration_main.cpp}::g_pt_model

uid (board_id*100 + connector) -> streaming model.

Non-default resolutions are stored (4-20 mA boards default to Physics, 0-5 V to Cubic); an absent uid means Cubic.

Latest thermocouple cold-junction temperature (°C) per T7 slot, from t7_bridge's CJC table {0x26, (slot-1)*0x20 + 0x0F}.

Absent until the first one arrives; a T7 TC sample with no junction yet is not published rather than converted against a guess.

g_uid_role

std::unordered_map<uint16_t, std::string> anonymous_namespace{calibration_main.cpp}::g_uid_role

uid -> role name (from [sensor_roles_*]).

Durable calibration is filed under the role, so it follows the sensor when its connector changes (see re-file-by-role in the stores). Empty for connectors with no configured role.
