Hello, I have been working on trying to integrate the PMOD I2S2 into my MKR Zero, using the I2S interface. I am hoping for some help troubleshooting why I cannot get any input data. The overall goal is to be able to read in an audio signal to my Arduino and trigger certain events based on the audio input. I am very new to working with Arduino and have gotten some basic projects done with some LED lights. I thought that the PMOD I2S2 module would be able to work with my Arduino since it has ports for the I2S protocol.
Here is how I wired the PMOD I2S2 into the Arduino MKR Zero:
ADIN MCLK -> Purple -> D12 (I2S_MCK[0])
ADIN LRCK -> Grey -> D3 (I2S_FS[0])
ADIN SCLK -> Black -> D2 (I2S_SCK[0])
ADIN SDOUT -> Brown -> A6 (I2S_SD0)
GND -> Blue -> GND
VCC -> Red -> VCC
Attached are photos of how I currently have the PMOD I2S2 wired into the Arduino. I have the PMOD Slave/Master jumper set to Slave.
After wiring up the PMOD to the Arduino, I pulled in the I2S library. From there, I implemented the most basic example presented to read data. With that basic example I am not getting any input data. I have the PMOD Line In connected by an AUX cable, connected to my laptop. I am not sure what I might be doing wrong or if it is even possible to interface the PMOD I2S2 with an Arduino. Maybe I have something misconfigured in my code or I have connected the wrong PMOD pins to the I2S inputs on the Arduino? Any help would be greatly appreciated.
