ESP8266 Community Forum

Hi all.

I have a *bit* of experience with the ESP8266, specifically the ESP-12-E. I have written various programs to control relays, serve pages via an AP from SPIFFS etc, all good and loving the chip.

I am however looking for the easiest way to play an audio file through the ESP8266 to a speaker. I need to play around 8 different audio clips, with high fidelity playback.

I have done some googling and see a mirage of ways to do this, what are your thoughts? I want to get started with as few external components as possible, but am aware I may need a DAC. I see the ESP8266 has I2S which seems relevant to outputting Audio, my concern is it uses the RX pin for serial I think, can I change serial / I2S pins?

even the simplest boardsearch should have brought you to

if you need serial in your sketch you can either swap uart0/1 or use softserial.

Hi schufti.

How do you mean swap UART 0/1?

What is soft serial?

I use this module:

And I use this library:
