Transport — fdo2::UartInterface<Derived>

CRTP base. Implement:

• void write(const uint8_t* data, size_t length);
• size_t read(uint8_t* out, size_t max, uint32_t timeout_ms);
• void flush_rx();
• Optional void delay_ms_impl(uint32_t ms);

Driver — fdo2::Driver<UartT>

Method	Description
ReadVersion()	#VERS → VersionInfo (D, N, R, S)
ReadUniqueId()	#IDNR → uint64_t
MeasureMoxy()	#MOXY → MoxyReading
MeasureMraw()	#MRAW → MrawReading
FlashLogo()	#LOGO
SetLineTimeoutMs / SetMeasureTimeoutMs / SetSlowCommandTimeoutMs	UART timeouts
LastDeviceErrorCode()	Parsed E after #ERRO

Types — fdo2_types.hpp

• DriverResult<T>, DriverError, ToString(DriverError)
• VersionInfo, FirmwareRevisionToDouble(R)
• MoxyReading, MrawReading
• moxy_status::* bitmask constants
• MoxyStatusOkForOxygen(uint32_t s) — true if S ≤ 1
• VolumePercentO2(p_o2_hpa, p_air_mbar)
• kFdo2G2DefaultBaud, kFdo2G2PowerUpSettleMs
