PmodMIC3 with CMOD A7

[BeamPower]

Hello,

Does Digilent have some guidelines on how to operate a PmodMIC3 with a CMOD A7 board?

First of all, is the CMOD A7 a good host platform for the PmodMIC3?

Or is the ARTY a better choice?

Is it possible to record sound, digitize it on the FPGA at 44.1 kHz, then send it to the PC via the USB port?

I looked all over the Digilent site and GitHub, but found nothing.

Thanks.

@BeamPower,

1. I don't see why the A7 wouldn't be a good host ... the comms path is fairly simple between the PMIC and just about any PMod host.
2. The ARTY should work just as well.
3. Is it possible?  Yes.  You should be able to record sound at a rate of 1Msps, but I doubt you'd actually get that much bandwidth.

I just recently plugged my own PMIC in, wrote up some code for it, but ... (sadly) I haven't tested it yet beyond a simple bench test.  Still, you can find my work here.  I've got it connected to a ZipCPU already, I just ... haven't done anything with it to know if it would really work or not.

Hi @BeamPower,

Unfortunately we currently do not have any HDL or an IP core for the PmodMIC3. Will that being said you should still be able to accomplish your goal with either board. I also found a project for the PmodMIC3 here done by @hamster with the Basys 3.

cheers,
