# LPS22HH
Arduino library to support the LPS22HH 260-1260 hPa absolute digital output barometer

## API

This sensor uses I2C, I3C or SPI to communicate.
For I2C it is then required to create a TwoWire interface before accessing to the sensors:  

    TwoWire dev_i2c(I2C_SDA, I2C_SCL);  
    dev_i2c.begin();

For SPI it is then required to create a SPI interface before accessing to the sensors:  

    SPIClass dev_spi(SPI_MOSI, SPI_MISO, SPI_SCK);  
    dev_spi.begin();

For I3C it is then required to create an I3C interface before accessing to the sensors:

    I3C.begin(I3C_SDA, I3C_SCL, 1000000U);

An instance can be created and enabled when the I2C bus is used following the procedure below:  

    LPS22HHSensor PressTemp(&dev_i2c);
    PressTemp.begin();
    PressTemp.Enable();

An instance can be created and enabled when the SPI bus is used following the procedure below:  

    LPS22HHSensor PressTemp(&dev_spi, CS_PIN);
    PressTemp.begin();
    PressTemp.Enable();

An instance can be created and enabled when the I3C bus is used with SETDASA (static-to-dynamic address assignment):

    LPS22HHSensor PressTemp(&I3C, LPS22HH_I3C_ADD_H);
    I3C.resetDynamicAddresses();
    I3C.assignDynamicAddress(PressTemp.getStaticAddress(), LPS22HH_DYNAMIC_ADDRESS);
    PressTemp.begin(LPS22HH_DYNAMIC_ADDRESS);
    I3C.setClock(12500000);
    PressTemp.Enable();

The access to the sensor values is done as explained below:  

  Read pressure and temperature.  

    float pressure;
    float temperature;
    PressTemp.GetPressure(&pressure);  
    PressTemp.GetTemperature(&temperature);

# Examples

There are several examples with the LPS22HH library.
* LPS22HH_DataLog_Terminal_I2C: This application shows how to get pressure and temperature data from the LPS22HH sensor over I2C and print them on terminal.
* LPS22HH_Datalog_Terminal_I3C: This application shows how to use the LPS22HH sensor over I3C using SETDASA.
