Classes
struct	fsw::t7::T7CalChannel
	One T7 input as calibration sees it. More...
class	fsw::t7::T7CalibrationMap
	Every PT / LC / TC input on every enabled T7, from config. More...

Namespaces
namespace	fsw
	Motorized ball valve position: raw ADC counts -> % open.
namespace	fsw::t7

Functions
uint8_t	fsw::t7::t7_logical_channel (uint8_t slot, uint8_t ain)
	Logical calibration channel for a T7 input.
uint16_t	fsw::t7::t7_uid (int board_id, int ain)
	uid of a T7 input: board_id * 100 + ain, the ESP32 scheme with the AIN as connector.
int32_t	fsw::t7::t7_counts (double volts)
	The calibration "ADC code" for a T7 reading: microvolts, rounded and clamped to int32.
double	fsw::t7::t7_volts (double counts)
	Volts from a calibration code.
std::array< uint8_t, 2 >	fsw::t7::cjc_table_id (uint8_t slot)
	Cold-junction table id for a slot.

Variables
constexpr uint8_t	fsw::t7::kCjcTableOffset = 0x0F
	Raw-table offset (within a slot's 32-entry block) of the cold-junction table: AIN15 does not exist on a T7, so the slot is free.
constexpr uint8_t	fsw::t7::kT7LogicalBase = 128
	First logical calibration channel for T7 inputs.
