  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: https://forum.digilentinc.com/topic/19342-driver-code-for-pmod-acl2-and-pmod-mic3/ 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: https://reference.digilentinc.com/learn/fund

    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 https://reference.digilentinc.com/pmod/pmod/mic3/ref_manual and click "user guide", it will bring you to https://reference.digilentinc.com/pmod/pmod/mic3/user_guide 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. http://hamsterworks.co.nz/mediawiki/index.php/Digital_Microphone It's pretty interesting how the MEMS microphones work - it seems to be much like this, but at audio frequencies:
