Detailed Description

Altitude2 Click example.

Description

This demo demonstrates the use of Altitude 2 Click to measure temperature, altitude and pressure.

The demo application is composed of two sections :

Application Init

Initializes I2C driver and performs the device reset, after which the calibration coefficients will be read. Determines the ratio value for temperature and pressure measurements. Calibration coefficients are necessary to read after the device reset.

Application Task

Gets temperature data in celsius value and pressure data in mbar value. Gets the calculated altitude value in meters which depends on the temperature and pressure measurements. Logs results on USBUART and repeats operation each second.

Note

Altitude is dependent from correct outside readings. It's calculated from pressure and temperature readings.

Note

If USB_UART_RX and USB_UART_TX are defined as HAL_PIN_NC, you will need to define them manually for log to work. See LOG_MAP_USB_UART macro definition for detailed explanation.
