Versatile and flexible Python State Machine library - Micropython Port
This repository is basically a set of tools to build and deploy (to pypi) the Micropython Port of the pysm library.
It's successfully tested against the ESP-32S ESP-WROOM-32 NodeMCU board.
import upip upip.install('upysm')Basic usage:
import machine import time from pysm import State, StateMachine, Event led = machine.Pin(2, machine.Pin.OUT) def on_enter(state, event): led.value(1) time.sleep(0.1) def on_exit(state, event): led.value(0) time.sleep(0.1) on = State('on') off = State('off') sm = StateMachine('sm') sm.add_state(on, initial=True) sm.add_state(off) sm.add_transition(on, off, events=['off']) sm.add_transition(off, on, events=['on']) on.handlers = {'enter': on_enter, 'exit': on_exit} off.handlers = {'enter': on_enter, 'exit': on_exit} sm.initialize() assert sm.state == on sm.dispatch(Event('off')) assert sm.state == off sm.dispatch(Event('on')) assert sm.state == onFor more examples and API description refer to the pysm documentation.
