Release notes 3.0.6838-stable

New Features

  • IMUFW-414 - Add support for the PULSE-20 IMU
  • IMUFW-386 - Enable FFT monitoring by default on standalone IMUs
  • IMUFW-420 - Add CAN bus data output support (Pulse-20)
  • IMUFW-383 - Support hard and soft iron calibration settings for magnetometer aiding (Pulse-20 & Pulse-40 Hardware version 2)
  • IMUFW-321 - Implement magnetometer sampling (Pulse-20 & Pulse-40 Hardware version 2)

Improvements

  • IMUFW-372 - PULSE-80: Reduce boot time down to 1000ms
  • IMUFW-363 - Improve accelerometers over range behavior with a clean saturation
  • IMUFW-360 - Increase frequency of CBIT checks for cluster based axis to 200Hz
  • IMUFW-242 - Make the IMU BIT status flag depend on the clock and calibration state
  • IMUFW-217 - Rework scaled clock mode

Release notes 2.0.3633-stable

New Features

  • IMUFW-202 - Add support for the PULSE-80 IMU
  • IMUFW-318 - Add support for the PULSE-40 hardware version 2
  • IMUFW-274 - Extract vibration monitoring information
  • IMUFW-214 - Add accelerometers startup self test check (PBIT)
  • IMUFW-208 - Rework IMU status implementation

Improvements

  • IMUFW-351 - Improved sensor startup behavior and settle time
  • IMUFW-281 - PULSE-40: Implement new gyroscopes and accelerometers filters reducing Bandwidth to 250Hz and improving susceptibility to shock and vibration
