In this example, a simple vibration monitoring algorithm is provided.
The classes recognized by this example are: vibration1 (no vibration), vibration2 (low vibration), vibration3 (high vibration).
For information on how to integrate this algorithm in the target platform, please follow the instructions available in the README file of the examples folder.
For information on how to create similar algorithms, please follow the instructions provided in the tutorials folder.
The accelerometer is configured with ±4 g full scale and 30 Hz output data rate.
Any sensor orientation is allowed for this algorithm.
Just one feature has been used (peak-to-peak) and applied to the accelerometer norm squared input.
The MLC runs at 30 Hz, computing features on windows of 18 samples (around 0.6 seconds).
One decision tree with just 2 nodes has been configured to detect the different classes. A meta-classifier has not been used.
- MLC0_SRC (70h) register values
- 0 = vibration1 (no vibration)
- 1 = vibration2 (low vibration)
- 2 = vibration3 (high vibration)
The configuration generates an interrupt (pulsed and active high) on the INT1 pin every time the register MLC0_SRC (70h) is updated with a new value. The duration of the interrupt pulse is 38.5 ms in this configuration.
