This document describes the features and characteristics of the STEVAL-MKI029V1 inclination analysis demonstration board, including detection and visual/audio representation of tilt on the X axis, tilt on the Y axis, circular motion of the board, and free-fall of the board. The board is based on the STM8S207R6 MCU and LIS331DLH MEMS.
The STEVAL-MKI029V1 is an inclination analysis demonstration board based on the STM8S207R6 MCU and LIS331DLH MEMS. It detects and provides visual or audio representation of tilt on the X and Y axes, circular motion, and free-fall events. The board utilizes multi-colored LEDs or music/rhythm patterns to display motion information and offers six different operating modes, including three musical modes and three silent modes.
| MCU | STM8S207R6 |
|---|---|
| MEMS Sensor | LIS331DLH |
| Power Source | 3 AAA batteries of 1.5 V each |
| Board Diameter | 84 mm |
| Board Height | 26 mm |
| Standby Timeout | 10 seconds |
The system detects the free-fall of the board and displays the information on the bi-color LED at the center of the board.
The system automatically enters standby mode when there is no motion for more than 10 seconds.
