X-NUCLEO-IKS01A3 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-IKS01A3 MEMS Inertial & Environmental Sensors Nucleo Expansion Board.

Firmware Library

Class X_NUCLEO_IKS01A3 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 LIS2MDL 3-Axis Magnetometer
3. a LIS2DW12 3-Axis Accelerometer
4. a LPS22HH MEMS Pressure and Temperature Sensor
5. a LSM6DSO 3-Axis Accelerometer and 3-Axis Gyroscope
6. a STTS751 MEMS Temperature Sensor

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_IKS01A3 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 XNucleoIKS01A3 *mems_expansion_board = XNucleoIKS01A3::instance(D14, D15, D4, D5, A3, D6, A4);

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.
