X-NUCLEO-IKS01A1 MEMS Inertial & Environmental Sensor Nucleo Expansion Board Firmware Package

Introduction

This firmware package includes Components Device Drivers and Board Support Package for STMicroelectronics' X-NUCLEO-IKS01A1 MEMS Inertial & Environmental Sensors Nucleo Expansion Board.

Firmware Library

Class X_NUCLEO_IKS01A1 is intended to represent the MEMS inertial & environmental sensors expansion board with the same name.

The expansion board is basically featuring four IPs:

  1. a HTS221 Relative Humidity and Temperature Sensor,
  2. a LIS3MDL 3-Axis Magnetometer,
  3. a LPS25H MEMS Pressure Sensor, and
  4. a LSM6DS0 3D Accelerometer and 3D Gyroscope

The expansion board features also a DIL 24-pin socket which makes it possible to add further MEMS adapters and other sensors (e.g. UV index).

It is intentionally implemented as a singleton because only one X_NUCLEO_IKS01A1 at a time might be deployed in a HW component stack. In order to get the singleton instance you have to call class method `Instance()`, e.g.:

// Sensors expansion board singleton instance
static X_NUCLEO_IKS01A1 *sensors_expansion_board = X_NUCLEO_IKS01A1::Instance();


Furthermore, library ST_INTERFACES contains all abstract classes which together constitute the common API to which all existing and future ST components will adhere to.
