IMU Guide

  • Read data from on-board inertial measurement unit (IMU) featuring 3-axis accelerometer and gyroscope
  • Configure sample time and resolution
  • Customize for your application

Specifications

A summary of the IMU is provided below.

Feature Parameter
Directions

*Identical configuration for FlexCase G
Acceleration Range ±2/±4/±8/±16 g
Gyroscope Range ±125/±250/±500/±1000/±2000/±4000 dps
Interrupts 2
Part Number ST ASM330LHH (FlexCase E)
ST ASM330LHB (FlexCase G)

The IMU is directly connected to the MCU via SPI. Use the FlexCase and IMU datasheets to set up communication or reference the IMU_k3.slx sample Simulink model.

Additional Information

The IMU is highly configurable. Using control commands, features can be configured such as:

  • Configure hardware filters
  • Change the acceleration/rotational speed limits
  • Configure capture mode
  • Detect acceleration events (orientation change, free-fall, wake-up)
  • Generate hardware interrupts
