  1. 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
  2. After finally finding a reason to start using my PMODamp3, I've created a little project that emits a very quiet 375Hz sine tone through an 8 Ohm speaker: http://hamsterworks.co.nz/mediawiki/index.php/PMODamp3 It might be of use to anybody who want to use this PMOD in a design as a starting point.
