Functions
constexpr std::string_view	fdo2::ToString (DriverError e) noexcept

constexpr double	fdo2::FirmwareRevisionToDouble (int32_t r) noexcept

constexpr bool	fdo2::MoxyStatusOkForOxygen (uint32_t s) noexcept
	Data sheet: normal operation implies S is 0 or 1 only.

MrawReading	fdo2::DecodeMraw (int32_t o_raw, int32_t t_raw, uint32_t s, int32_t d_raw, int32_t i_raw, int32_t a_raw, int32_t p_raw, int32_t h_raw) noexcept

double	fdo2::VolumePercentO2 (double p_o2_hpa, double p_air_mbar) noexcept
	Volume % O₂ when p_air at the sensing membrane equals back-side pressure P.

Variables
constexpr uint32_t	fdo2::kFdo2G2DefaultBaud = 19200U

Detailed Description

FDO2-G2 UART types, scaling, and status decoding (PyroScience data sheet v5).

Numeric scaling and command names follow the FDO2-G2 data sheet (document version v5, 03/2026), §4 Communication Interface. This is distinct from the broader “PyroScience Unified Protocol” used on laboratory / multi-channel instruments (MEA, eighteen-word results, etc.).
