Interfacing PMOD-DA2 to PYNQ-Z1

[Nitish]

Hi,

 

I am trying to interface and get readings out of PMOD DA2.

https://reference.digilentinc.com/reference/pmod/pmodda2/reference-manual

 

As I understand this has a SPI interface I need to write a C code on SDK to configure the PMOD switch for a SPI interface and also drive signals for transfer data to the PMOD.

Could anyone guide me the process of how this needs to be done. Thanks in advance!

Hi @Nitish,

We have IP cores for many of our Pmod IP's. Here is our vivado library. Unfortunately, we currently do not have an IP core for the PmodDA2. Here and here are forum threads that deals with the PmodDA2. Here is our resource page for the PmodDA2. Here is a tutorial on making your own custom IP with the Zybo(zynq processor) that should work for the Pynq board as well.  Another potential way to do this is using the GPIO and add a block feature in Vivado 2016.x and up. You use add a block with HDL code and connect it to a GPIO IP block. I have attached a forums members completed project that does this with the PmodAD1.
