Stereo Out + HF - Mic/Mono Out Simultaneously

Postby barometre » Mon Mar 09, 2020 3:10 pm

Hi,

I am experimenting with the ESP32's a2dp function. Iniatally I would like to use a2dp output with a stereo I2S dac. I have one more I2S for the microphone input of HFP function however I would like to use a standalone speaker for the HFP output. As I know, onboard ADC and DAC requires I2S to work. Is there any possibility to to create such a setup with ESP32?

A2DP -> I2S0 Stereo DAC
HF Mic -> I2S1 Mono ADC
HF Speaker -> Mono Audio Output?

Thanks
