<![CDATA[M5STACK CORE 2 SOUNDS]]>Ladies and gents I have been struggling to work out the best way to convert wav files to C arrays for playing sound using I2S audio output. Has anyone got a clearly documented solution for this. Would have been great in the examples to also include this in future releases. The 2 sounds work fine supplied with the core 2 however no guidance on how one goes about creating their own. All help appreciated. Thanks

Can you please tell me more about your guide? Is it possible to buy it somewhere? is it the same as what is mentioned in your signature: UIFlow handbook? I would be very much interested, thanks!

https://community.m5stack.com/topic/3179/how-to-generate-a-beep

The solution suggested by @AgreeDK does perfectly work! (thanks to you!)

I would however really like M5 people to update the Core2 lib with a simple beep function like on the Core

Thanks

On the same topic it would really be great adding in the C++ M5Core2.h lib a method to play simple beeps.
I just need to beep on button press but it looks like I have to load a .C sound file in the Core2 flash memory which is totally overkill.

If someone has an idea how to play simple beep without loading a file can you please help me?

Thanks a lot!
