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

Introduction

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

Example Application

First of all, the example application outputs information retrieved from the Expansion Board over UART. Launch a terminal application (e.g.: PuTTY on Windows, Minicom on Linux) and set the UART port to 9600 bps, 8 bit, No Parity, 1 stop bit.

The "Sensors Reader" program is a more complex example of how to use the X-NUCLEO-IKS01A1 expansion board featuring among others:

Support for LSM6DS3 3D Accelerometer & Gyroscope (on DIL 24-pin socket) including free-fall detection
Usage of LED & Ticker
Exploitation of wait for event
(Top-/Bottom-Half) Interrupt handling
