Enumeration Type Documentation

◆ SensorKind

enum class fsw::calibration::SensorKind

strong

Which family of sensor a channel belongs to.

logical_ch is (slot - 1) * 10 + connector with slot = board_id % 10, and check_board_slots only prevents two boards of the SAME kind sharing a slot. So PT board 22 and LC board 42 are both slot 2, and PT uid 2201 and LC uid 4201 both land on logical channel 11. The logical-channel maps below are written from a uid-ordered map, so the higher uid silently won: on 2026-09-13 a load cell's curve overwrote a 5000 psi transducer's on disk. The kind namespaces those maps so the two cannot collide.

Function Documentation

◆ lc_tare_entity()

std::string fsw::calibration::lc_tare_entity	(	uint8_t	board_id,
		uint8_t	connector )

The publish-path entity name for an LC channel: "LC<slot>_Cal.CH<connector>", where slot is board_id % 10 with 0 -> 10 — the same rule DatabaseConfig uses to name the calibrated LC VTables, and the same board_number the LC publish path already holds.

It exists as one shared function because the failure mode of a second copy is specific and has already happened: slot is NOT board_id, so PT board 22 and LC board 42 are both slot 2, and deriving a uid back out of an entity string collides them. Node must key on this string rather than re-derive it.
