We are pleased to announce the release of IMU firmware 3.0 supporting the Pulse-20 IMU, Pulse-80 IMU and Pulse-40 Hardware version 2 ; but also key improvements and bugfixes.
Firmware Download
You can download the firmware package below for your Pulse IMU.
The archive contains a CLI (Command Line Interface) tool and documentation to easily update your device firmware.
Key highlights
New IMU support
The Firmware 3.0 offers the support of sub minature industrial grade IMU, the Pulse-20.
Pulse-20
Sub miniature industrial grade MEMS IMU
Pulse-80
High tactical grade MEMS IMU
Pulse-40 v2
Unannounced yet iteration of the Pulse-40
Built-in vibration spectrum analyzer (real time high bandwidth FFT)
This new feature, compatible on all existing IMU (Pulse-20, Pulse-40, Pulse-80) allows to measure the vibrations received by the IMU.
It is performed by running FFT computation on the raw data of the accelerometers, giving a significantly higher bandwidth than on the filtered IMU data.
The data is available in 2 formats:
A full Spectrum (SBG_ECOM_LOG_FFT_RAW)
A synthetic report giving the peak frequency and its magnitude for 4 equally distributed frequency bands (SBG_ECOM_LOG_FFT_REPORT)
