I2S 8CH ADC

Postby alongoldman » Fri May 18, 2018 5:43 am

Hi,
I'm working on a project to connect AK5538VM ADC to ESP32.
The ADC will provide the MCLK so it would be the master in this setup.

The AK5538VM is an 8CH audio ADC, it can output data in 2 ways:
1. through 4 discrete pins, each pin outputs a 2CH standard I2S audio stream
2. through 1 discrete pin outputting all the data in TDM format

What would be your recommended approach ?
How do I configure ESP32 I2S parallel input mode ?
Alternatively, can ESP32 work in AK5538VM TDM format ?
