# ILPS22QS

Arduino library to support the ILPS22QS absolute digital output barometer

## API

This sensor uses I2C, SPI, or I3C 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();

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

    ILPS22QSSensor sensor(&dev_i2c);
    sensor.begin();
    sensor.Enable();

An instance can be created and enabled when the I3C bus is used with SETDASA:

    ILPS22QSSensor sensor(&I3C, ILPS22QS_I3C_ADD);
    I3C.begin(I3C_SDA, I3C_SCL, 1000000U);
    I3C.resetDynamicAddresses();
    I3C.assignDynamicAddress(sensor.getStaticAddress(), 0x30);
    sensor.begin(0x30);
    sensor.Enable();

An instance can be created and enabled when the I3C bus is used with ENTDAA (dynamic address discovery):

    ILPS22QSSensor sensor(&I3C);
    I3C.begin(I3C_SDA, I3C_SCL, 1000000U);
    I3C.resetDynamicAddresses();
    I3C.discover(devices, 8, &found);
    // find dynAddr by matching ILPS22QS_I3C_PID in discovered devices
    sensor.begin(dynAddr);
    I3C.setClock(12500000);
    sensor.Enable();

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

    ILPS22QSSensor sensor(&dev_spi, CS_PIN);
    sensor.begin();
    sensor.Enable();

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

Read pressure and temperature.  

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

## Examples

* ILPS22QS_DataLogTerminal_I2C: This application shows how to get pressure and temperature data over I2C.

* ILPS22QS_DataLogTerminal_I3C: This application shows how to get pressure and temperature data over I3C using SETDASA.

* ILPS22QS_DataLogTerminal_I3C_ENTDAA: This application shows how to discover and use ILPS22QS over I3C.
