Support for NRF52xxx in the MP3_Decoder

[aovestdipaperino]

Hello, I was able to add support for NRF52xxx to the decoder which is simply:

• removing the log_e and log_i statements (need to find a replacement)
• use the standard malloc

I've put mine here, it would be interesting if the mp3_decoder.* can somewhat be kept in sync (maybe a different repo?)

The NRF52xx are Bluetooth modules, right? The BT integrated in the ESP32 only works properly with a sample rate of 44100Hz. Can you also use other sample rates, e.g. 48000 or 22050 with NRF52?

[aovestdipaperino]

Yes, different rates are supported.
See table here
It's not exhaustive as I've seen 22.05KHz mentioned as well in some code.

Thank you for your feedback. Then I'll get a NRF51822, there are 2 on Amazon for 10€, that's affordable, and will experiment with it. I have your sample code as a template :-))

The Seeed Xiao ones are very good.
