Demonstration functional description

4.4.5

Compass

Overview

The Compass module application allows to demonstrate the integration of the LSM303C

3-axis electronic compass embedded on the STM32L476G discovery board.

Features

•

A real time display in degree of the direction versus the magnetic north

•

A calibration step is required in X/Y/Z axis to get the motion data from the application. It

consists in rotating the board by 360 degrees in all 3 axis. The calibration data are

saved in backup area.

4.4.6

Sound meter

Overview

The sound meter module demonstrates the perfect integration of a sound meter audio

library. It uses the audio recording capability of the digital microphone embedded on the

STM32L476G discovery board.

Features

•

16-bits PCM data input with a sample rate at 48 kHz (mono)

•

A-weighting pre-filter

•

Real time display of the sound level every 250ms with average done every 100ms
