namespace LPS22HB
STMicroelectronics LPS22HB sensor.
The STMicroelectronics LPS22HB is a MEMS nano pressure sensor: 260-1260 hPa absolute digital output barometer.
For technical documents and a complete description of the sensor features please refer to the official documentation at: https://www.st.com/en/mems-and-sensors/lps22hb.html
To create a STMicroelectronics LPS22HB sensor use the HUX_DECLARE_SENSOR
construct:
HUX_DECLARE_SENSOR(sensor_name, hux::sensors::STMicroelectronics::LPS22HB);
Simulation data
To define simulation data for a STMicroelectronics LPS22HB sensor use the HUX_DECLARE_SIMULATION_DATA
construct,
making sure that the simulation data match the following data type:
-
typedef hux::tuple<std::vector<float>, std::vector<float>, std::vector<hux::uint64_t>> hux::sensors::STMicroelectronics::LPS22HB::simulation_data_t
The type of data required for simulation purposes.
A hux::tuple of std::vector of the following types:
float: Temperature in Celsius degrees
float: Pressure in hPa (hectoPascal)
hux::uint64_t: Unix timestamp in milliseconds of the data generated by the sensor
This example shows how to load simulation data for a STMicroelectronics LPS22HB sensor from a CSV file whose columns are separated by semicolon (“;”):
HUX_DECLARE_SIMULATION_DATA(sim_data,
hux::simulation::load_csv<float, float, hux::uint64_t>("dataset.csv", ";"))
);
HUX_DECLARE_SENSOR(sensor_name, hux::sensors::STMicroelectronics::LPS22HB, sim_data);

Configurations
Initial configuration
To define an initial configuration for a STMicroelectronics LPS22HB sensor
use the HUX_DECLARE_SENSOR_CONFIGURATION
construct:
HUX_DECLARE_SENSOR_CONFIGURATION(conf_name, hux::sensors::STMicroelectronics::LPS22HB,
.PARAM_1 = VALUE_1,
.PARAM_2 = VALUE_2,
...
);
HUX_DECLARE_SENSOR(sensor_name, hux::sensors::STMicroelectronics::LPS22HB, {}, conf_name);
where PARAM_1, PARAM_2, … can be any of the following:
Note
If a parameter is not specified within the sensor configuration its default value is used.
Valid configuration values
Each sensor model has its own configuration values that are permitted by the manufacturer and supported by Huxon. The valid configuration values for the configuration parameters of the STMicroelectronics LPS22HB are listed below:
Dynamic configuration
The Huxon language provides the capability to reconfigure sensor parameters dynamically while the application is running. This allow to change the behavior of a sensor in response to specific events.
To dynamically reconfigure a STMicroelectronics LPS22HB sensor, it is necessary to create a configurator through
the HUX_SENSOR_CONFIGURATOR_BUILDER
and register it to the sensor using HUX_REGISTER_SENSOR_CONFIGURATOR
:
HUX_DECLARE_SENSOR(sensor_name, hux::sensors::STMicroelectronics::LPS22HB);
...
auto configurator = HUX_SENSOR_CONFIGURATOR_BUILDER(hux::sensors::STMicroelectronics::LPS22HB)
.add_PARAM1_cfg_chan(param1_channel)
.add_PARAM2_cfg_chan(param2_channel)
...
.finalize();
HUX_REGISTER_SENSOR_CONFIGURATOR(sensor_name, configurator);
where param1_channel, param2_channel, … are channels that generate configuration values, while the configurator builder methods: add_PARAM1_cfg_chan, add_PARAM2_cfg_chan, … bind such channels to the parameters they will configure. The configurator builder methods can be any of the following:
-
template<hux::channels::IsChannelOf<float> channel_t>
inline constexpr const auto add_ODR_cfg_chan(channel_t channel) const Configures a channel for the ODR (Output Data Rate) parameter.
