Finite State Machine
This repository provides information, examples and configurations of the Finite State Machine (FSM) feature available in some products in the ST sensors portfolio.
Finite State Machine processing allows moving some algorithms from the application processor to the STMicroelectronics sensor, enabling consistent reduction of power consumption. The sensor can be configured to detect user-defined motion patterns.
A Finite State Machine is a mathematical abstraction used to design logic connections. It is a behavioral model composed of a finite number of states and transitions between states, similar to a flowchart in which it is possible to inspect the way logic runs when certain conditions are met. The state machine begins with a Start state, goes to different states through transitions dependent on the inputs, and finally ends in a specific state (called Stop state). The current state is determined by the past states of the system.
The results of the Finite State Machine can be read from the application processor at any time. Furthermore, there is the possibility to generate an interrupt when a user-defined motion patterns is detected.
Repository overview
This repository is structured as follows:
- An application_examples folder, containing examples of applications ready to be used with the sensor.
- A configuration_examples folder, containing examples of configurations using different ST hardware and software tools.
