/**

* @file web-radio.ino
|
||
|
|
* @brief Web radio example for the Guition JC4880P443C_I_W (ESP32-P4) board
|
||
|
|
* with onboard ES8311 codec + NS4150 speaker amp, via I2SCodecStream and
|
||
|
|
* EncodedAudioStream. This is a test if the wifi on this board is fast enough
|
||
|
|
* to stream mp3 audio from the internet. We use the TinyGPU library to
|
||
|
|
* determine the pins.
|
||
|
|
*
|
||
|
|
* The speed seems to be sufficient, but I noticed it bo be quite instable and
|
||
|
|
* to hang the board after a while. I suspect that the wifi is not stable enough
|
||
|
|
* on this board.
