Micropython Example:

import os, sys, io
import M5
from M5 import *
from hardware import *

label0 = None
rotary = None

def btnA_wasClicked_event(state):
    global label0, rotary
    rotary.reset_rotary_value()
    label0.setText(str(rotary.get_rotary_value()))

def setup():
    global label0, rotary

    M5.begin()
    Widgets.fillScreen(0x222222)
    label0 = Widgets.Label("0", 96, 80, 1.0, 0xffa000, 0x222222, Widgets.FONTS.DejaVu72)

    BtnA.setCallback(type=BtnA.CB_TYPE.WAS_CLICKED, cb=btnA_wasClicked_event)

    rotary = Rotary()

def loop():
    global label0, rotary
    M5.update()
    if rotary.get_rotary_status():
        label0.setText(str(rotary.get_rotary_value()))

if __name__ == '__main__':
    try:
        setup()
        while True:
        loop()
    except (Exception, KeyboardInterrupt) as e:
        try:
        from utility import print_error_msg
        print_error_msg(e)
        except ImportError:
        print("please update to latest firmware")
