Atom S3R with Atomic SPK Base

[adr1a]

I'm trying to develop a toy for my son that plays a wav every time the button is pressed, but it seams that base_spk.playWavFile is blocking the main thread.

What can I do?

import os, sys, io
import M5
from M5 import *
from hardware import I2C
from hardware import Pin
from base import SpeakerBase

label0 = None
label1 = None

label3 = None

base_spk = None
step16_0 = None


def setup():
  global label0, label1, title0, label2, label3, i2c0, base_spk, step16_0

  M5.begin()
  Widgets.fillScreen(0x000000)
  label0 = Widgets.Label("Volume:", 3, 20, 1.0, 0xffffff, 0x222222, Widgets.FONTS.DejaVu12)
  label1 = Widgets.Label("label1", 61, 20, 1.0, 0xffffff, 0x222222, Widgets.FONTS.DejaVu12)
  title0 = Widgets.Title("Music", 3, 0xffffff, 0x0000FF, Widgets.FONTS.DejaVu18)
  label2 = Widgets.Label("Status:", 4, 38, 1.0, 0xffffff, 0x222222, Widgets.FONTS.DejaVu12)
  label3 = Widgets.Label("label3", 62, 38, 1.0, 0xffffff, 0x222222, Widgets.FONTS.DejaVu12)

  i2c0 = I2C(0, scl=Pin(1), sda=Pin(2), freq=100000)
  base_spk = SpeakerBase(1, 5, 39, 38)
  try:
    print('Init SD Card')
    print(os.listdir('/sd/samples'))
  except:
    sdcard.SDCard(slot=3, width=1, sck=7, miso=8, mosi=6, cs=None, freq=20000000)

  print('Setting volume')
  base_spk.setVolumePercentage(0.25)
  print('playing wav')
  base_spk.playWavFile('/sd/samples/sample-3s.wav')
  print('wav played')
  print('hello M5')


def loop():
  global label0, label1, title0, label2, label3, i2c0, base_spk, step16_0
  M5.update()
  print(os.getcwd())
  label1.setText(str(base_spk.getVolume()))
  label3.setText(str(base_spk.isPlaying()))
  time.sleep(1)
  if BtnA.isPressed():
    print('button pressed')
