Problem speaker with M5stickC Plus

vgamlc

I am using M5stickc plus at the moment I am very happy with them, but I have had a problem and I cannot find a solution.
I am unable to make a beep sound and I am not listening because, I am attaching the code to see if they can help me.

ERRROArduino:1.8.13 (Windows 10), Tarjeta:"M5Stick-C, Default, 1500000, None"
C:\DISEÑOS\Arduino\sketch_nov25b\sketch_nov25b.ino: In function 'void loop()':
sketch_nov25b:51:8: error: 'class M5StickCPlus' has no member named 'Speaker'
exit status 1
'class M5StickCPlus' has no member named 'Speaker'

Thanks in advance.

Hello @vgamlc

I think the correct function to call is: M5.Beep.beep();.

Cheers

Thanks, you are a machine and fast.

Another issue, I cannot change the volume on my M5stack Plus. Some help?

Hi @vgamlc

I don't think you can change the volume of the beep. Although there is a setVolume() function the volume is only used in the PlayMusic() function, but not for the beep.

Please also refer to the Speaker source code

Thanks
Felix
