Re: I2S Slave mode with external MCLK

Then you'll need to generate BCLK and WCLK for esp32 too.
I did that with help of FPGA, that works.

I'm not sure if ESP32 can sync to external MCLK and generate BCLK and WCLK internally, AFAIK there was a bug in the chip with this mode. Please double check ERRATA.

Re: Audio USB/BT/Wi-Fi Amanero-like module

Thanks! Well, it's true that ESP-S2 has got USB OTG, but it can operate only at full speed mode (12mbits/s), which is not enough for 24bit/192kHz sample rate or higher. That is the main reason for having Amanero MCU on board. Another drawback is that ESP32-S2 is a single core SoC, so it will be extr...

Audio USB/BT/Wi-Fi Amanero-like module

Hi, I personally used the Amanero modules for my audio devices and never had any problems with drivers or it's hardware, so I bought licenses for integration in my projects a while ago. The main disadvantage was lack of possibility to communicate from PC to, for example I2C port, for sending configu...
