BNO080 Driver

by Jamie Smith / USC Rocket Propulsion Lab

After weeks of development, we are proud to present our driver for the Hilcrest BNO080 IMU! This driver is inspired by SparkFun and Nathan Seidle's Arduino driver for this chip, but has been substantially rewritten and adapted.

It supports the main features of the chip, such as reading rotation and acceleration data, as well as some of its more esoteric functionality, such as counting steps and detecting whether the device is being hand-held.

Features

  • Support for 15 different data reports from the IMU, from acceleration to rotation to tap detection
  • Support for reading of sensor data, and automatic checking of update rate against allowed values in metadata
  • BNO_DEBUG switch enabling verbose, detailed output about communications with the chip for ease of debugging
  • Ability to tare sensor rotation and set mounting orientation
  • Fully synchronous and does not use interrupts, so operation is reliable and repeatable
  • Calibration function
