Support STA333BW power-amplifier IC #1894

Closed renne closed 6 years ago

renne commented 6 years ago

Today I received a STA333BW-based 13$ USB power-amplifier with 2x20W. It sounds pretty well. In my opinion ESP32 and STA333BW would make quite a couple. With two STA333BWs on the two I2S-outputs of the ESP32 it would even be possible to drive Bi-Amp speakers. And with four I2S microphones far-field filtering would be great. This would be quite a voice-assistant and multi-room audio platform.

Closing this, as this issue tracker is not the right place for hardware design discussion. Please use esp32.com forum instead.

OK. The issue was about I²C-API/library support in the ESP-32 IDF.

Hi @renne,

Please check ESP-ADF that provides I²C-API/library support in with ESP32 IDF.

There are two audio boards by Espressif available that support speakers and microphones.

ESP32-LyraT - already supported by ESP-ADF
ESP32-LyraTD-MSC - API support is coming

Maybe you will find them interesting or inspiring to bootstrap a solution with STA333BW.

I created a new issue in ESP-ADF as a starting point for more powerful amplifiers than on the LyraT.
