STEVAL-MKI029V1 Inclination analysis demonstration board based on the STM8S207R6 MCU and LIS331DLH MEMS Data brief Features Detects and provides visual/audio representation of: tilt on X axis tilt on Y axis circular motion of the board free-fall of the board Displays motion information using multi- colored LEDs or music/rhythm patterns Provides six different operating modes Offers a standby function for low power consumption Monitors the 3 AAA batteries and displays their STEVAL-MKI029V1 status on the LEDs There are three musical modes in which Provides additional MCU I/Os for future music/rhythm is played based on the extensions mode/motion of the board. There are also three silent modes, for a total of six different modes of Equipped with a SWIM connector for operation. debugging capability Compliant with RoHS directives The STEVAL-MKI029V1 can be switched from one mode to another by pressing the on-board MODE button. To reduce power consumption, the Description system automatically enters standby mode when there is no motion for more than 10 seconds. The The STEVAL-MKI029V1 inclination analysis system wakes up from standby when a board is a handheld demonstration board which vibration/motion is detected. The STEVAL- detects the tilt on X-axis and tilt on Y-axis. The MKI029V1 also monitors the batteries, and allows visual representation of this information is done the user to check their status at any time. When using colored LEDs placed in two circles. low battery is detected, the system alerts the user The system can detect the free-fall of the board and enters into no operation to avoid the system and display the information for this event on the malfunction. bi-color LED at the center of the board. The board is equipped with free MCU I/Os for the The system can also be configured to detect the external interface, and a SWIM connector is circular motion of the board, in which LED included to provide in-circuit debugging capability. patterns are generated depending on board The system can be powered using 3 AAA movement. batteries of 1.5 V each. The board is of circular The STEVAL-MKI029V1 also features a shape, with a diameter of 84 mm and a height of demonstration mode. In this mode, different LED 26 mm. patterns are displayed irrespective of the The board is RoHS compliant. position/motion of the board, making the system suitable for exhibitions and seminars.
