# upysm
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](https://github.com/pgularski/pysm) library.
It's successfully tested against the ESP-32S ESP-WROOM-32 NodeMCU board.
# Installation
```python
import upip
upip.install('upysm')
```
# Usage
Basic usage:
```python
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 == on
```
