Function Documentation

DecodeMoxy()

MoxyReading fdo2::DecodeMoxy ( int32_t  o_raw, int32_t  t_raw, uint32_t  s  )

inlinenoexcept

DecodeMraw()

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  )

inlinenoexcept

FirmwareRevisionToDouble()

constexpr double fdo2::FirmwareRevisionToDouble ( int32_t  r )

constexprnoexcept

Returns

Firmware as major.minor (R / 100.0).

GetDriverVersion()

const char * fdo2::GetDriverVersion ( )

inlinenoexcept

Driver version string (from the generated fdo2_version.h).

MoxyStatusOkForOxygen()

constexpr bool fdo2::MoxyStatusOkForOxygen ( uint32_t  s )

constexprnoexcept

Data sheet: normal operation implies S is 0 or 1 only.

ToString()

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

constexprnoexcept

VolumePercentO2()

double fdo2::VolumePercentO2 ( double  p_o2_hpa, double  p_air_mbar  )

inlinenoexcept

Volume % O₂ when p_air at the sensing membrane equals back-side pressure P.

Parameters

p_o2_hpa	Partial pressure O₂ [hPa] (from #MOXY / #MRAW O scaling).
p_air_mbar	Ambient / vent-path pressure [mbar] (from #MRAW P scaling; mbar ≈ hPa for this ratio per data sheet §2).
