Communication between Basys3 and PDM module on an audio analyzer ?


Hi all,

I'm using pmodMic 3 and Basys 3 for acoustic signal read in and analyses, so far I've been using terminal software on PC to read the data in. However, my professor purchased a audio analyzer for our lab lately, therefore I got a chance to feed the acoustic signal in directly from my mic (+board) to the analyzer. The analyzer we're using is Audio Precission apx555. There's a PDM module on the box, I'm aware that pmodMic 3 is not PDM but I'm assuming it could achieve the result of PDM by interpolation (?). I'm just wondering if there's any approach to make coummunication between my basys 3 board and the PDM module interface on the analyzer? I attached a pic of the PMD module interface on the box.





Not sure if I made myself clear.. Thank you in advance!
