That's a different core. I did not have an I2S DAC or a regular DAC, the only viable option was to use a transistor and speaker, but according to him it is better not to go that route; due to this, I just Jul 13, 2020 · Finally done with this project! I am now able to use an ESP8266 module, or a board like the Wemos D1 Mini, to play MP3 directly - no external storage or decoder needed thanks to a library called ESP8266Audio. ssid the ssid (station name) to be used. pcbgogo. However you need another DAC that supports master mode. I need to send audio data with UDP using a Cpp Program, and I need to use I2S to do this. In the Setup, we set up our serial connection, as we will be using the Serial Plotter to display our audio waveforms. Before we get into the code, make sure you download the library from the below link and add it to Arduino IDE. However, I cannot control the Speed or Volume due to what I think is the fact that the program does not exit the while loop in the XT_I2S_Class::FillBuffer() It appears that NumBytesWritten is always above 0.
