  1. Hello everyone, I’m a newbie on working on zedboard, and I want to use my Zedboard to communicate with Pmod MIC3 this time. I did a few researches about how to use the Pmod MIC3, and I think I found something useful in another post, link: I’m really appreciate and thanks for their help, but unfortunately I still have no idea of how to make my Pmod MIC3 to run with my Zedboard. I know Pmod MIC3 is using SPI communication protocol and I read what SPI is, link:

    Hello, I'm trying to make a voice-activated on a nesys4 and i want to use the pmodMic3.To do si, I want to use the SPI protocol but i don't know how. So how can i choose the SPI protocol ? Furthermore, I got some issues when filling in the constraint's file. On the web-site of Diligent, the pin2 is not connected but, the protocol SPI show the opposite. So how to Well connect the in/out of the peripheral to the board in the constraint's file? Thank you in advance for your answer. Junior
  3. We are trying to investigate whether the PmodMIC3 would be a suitable microphone to use for a project, but we cannot find details on how the 12-bits of digital data sent should be interepreted. There is a link on your website to a "user guide" but that link is broken. Go to and click "user guide", it will bring you to where it says "This topic does not exist yet". Is it possible to repair this link so we can obtain this user guide? Thank you very much.
  4. I got a bit bored yesterday, and hooked the PMODmic3 up to my PMODamp3 design, and put a small delay (of 32768 samples). The VHDL module for the microphone interface is actually surprisingly small : ---------------------------------------------------------------------------------- -- Engineer: Mike Field <[email protected]> -- -- Module Name: pmod_mic3 - Behavioral -- -- Description: Sample input form a PMOD_MIC3, once every 256 ticks of the -- master clock (mclk). ---------------------------------------------------------------------------------- library IEEE; use IEEE
  5. I've finally got my PmodMIC3 out of it's back and have it up and running. It's pretty interesting how the MEMS microphones work - it seems to be much like this, but at audio frequencies:
