accelerometer (only accelerometer is supported in fwpackage),
environmental and acoustic MEMS sensors.
Key features
• Developed for STM32F469AI with easy portability across different
MCU families
• Middleware including algorithms for advanced time and frequency
domain signal processing for vibration analysis:
• Programmable FFT size (256, 512, 1024, 2048 points)
• Programmable FFT overlapping
• Programmable acquisition time window
• FFT averaging during acquisition time
• Programmable windowing (Flat Top, Hanning, Hamming)
• Speed RMS moving average, acceleration max peak.
• Middleware integrating microphone algorithms for:
• PDM to PCM
• Sound pressure
• Audio FFT
• Environmental, acoustic and vibration data monitoring through freely available
terminal emulator.
• Example firmware to communicate with STEVAL-IDP004V1 (IO-Link master
capable, multi-port evaluation board) and dedicated PC GUI.

The Predictive Maintenance demonstration project (PredMaint_SVR), inside STSW-BFA001V1\Projects\Demonstrations\
Predictive_Maintenance folder, allows programmable vibration thresholds and give, in output, motor status details coming from
time and frequency vibration analysis.
The motor status are:
- Good
- Warning
- Alarm
Fix STEVAL-IDP005V1

User can modify the alarm and warning thresholds for Speed RMS, Acc peak and spectral band. It is done in precompiling
phase on MotionSP_Threshold.h file. Spectral band can be subdivided in 8, 16, 32 or 64 subrange.

Open the PredMaint_SVR project fromSTSW-BFA001V1\Projects\Demonstrations\Predictive_Maintenance folder*
(*) to change thresholds and recompile firmware it is necessary install one of the supported IDEs
