# LPS22HH
Arduino library to support the LPS22HH 260-1260 hPa absolute digital output barometer
## API
This sensor uses I2C 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();
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();
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);
