  1. I'm using Nexys A7-100T developmennt board. I'm having issues getting Pmod I2S2 to work. This is my test design: The clocking wizard creates a 11.289MHz master clock. The tranceiver module I'm using can be found here: https://forum.digikey.com/t/i2s-pmod-quick-start-vhdl/13065. It seems to be generating the serial and ws (word select) clocks properly. The problem is that I'm not getting any signal from the ADC. sdout pin stays high no matter what. Even if LINE IN was floating, I would expect zeros between left and right channel data. Is the Pmod faulty or am I mis
  2. I am new to this so I am just guessing how to out stuff together. I want to use the PmodI2S2 for Stereo Audio Input and Output. I am using a Cora z7 with a ZYNQ. I want to try and make two things: A. Connect the PmodI2S2 via Axi and then write a software application in Vitis to send and receive audio data. B. Connect the Pmod12S2 to logic and modify audio data. Possibly make an oscillator. The "Pmod I2S2 FPGA Volume Control Demo" in the resources centre says it uses an AXI streaming interface. So for part A. I made a new IP with an AXI streaming interface (ju
