Hi all,

In France we use daylight saving time.
clocks was set forward by one hour in the spring ("spring forward") and set clocks back by one hour in autumn ("fall back") to return to standard time.

how to deal with UIFlow?

Thanks.

Thanks for your reply, when i test this code in UIFlow 1.7.7 on Fire:

from machine import I2S
import os, uos
from wav import wave

#initialize the I2S device
i2s = I2S(  mode = I2S.MODE_MASTER | I2S.MODE_TX | I2S.MODE_DAC_BUILT_IN,
            rate = 16000,
            bits = 16,
            channel_format = I2S.CHANNEL_ONLY_RIGHT,
            data_format = I2S.FORMAT_I2S_MSB)

#uncomment the following line if you have issues mounting the sd
#uos.sdconfig(uos.SDMODE_SPI,clk=18,mosi=23,miso=19,cs=4)

#create a function to play the wav
def wav_player(fname):
    wav = wave.open(fname)
    i2s.set_dac_mode(I2S.DAC_RIGHT_EN)
    i2s.sample_rate(wav.getframerate())
    i2s.bits(wav.getsampwidth() * 8)
    i2s.nchannels(wav.getnchannels())
    i2s.volume(20)

    while True:
        data = wav.readframes(1024)
        if len(data) > 0:
            i2s.write(data)
        else:
            wav.close()
            break

# Playing WAV audio file
lcd.clear()
lcd.print('working',0,0,0xffffff)

try:
    uos.mountsd()
except:
    os.mountsd()
    lcd.print('sd card not mounted',0,50,0xffffff)
    pass

while True:
        wav_player('/sd/test.wav')
        i2s.stop()
        wait(5)

I have another error on line 39:

module object has no attribute 'mountSD'

Hi all,

I try to follow this tutorial to play wav file on M5stack Fire: https://m5stack.hackster.io/lukasmaximus89/m5stack-rfid-face-wav-playing-flashcard-program-526cb5

But I have a little problem with the module wave. When i run my micropython code i have an error on the fire:

no module named 'wave'

Thanks for your help.
