You can see how to use the DMA for data transfer here:

Tutorial: PYNQ DMA (Part 2: Using the DMA from PYNQ)

PYNQ DMA tutorial (Part 2: Using the DMA from PYNQ) This tutorial shows how to use the PYNQ DMA class to control an AXI DMA in a hardware design. This is the second part of a DMA tutorial. PYNQ DMA tutorial (Part 1: Hardware design) shows how to build the Vivado hardware design used in this notebook. All the source files for the tutorial are hosted on a GitHub repository and this post is a Markdown version of a Jupyter notebook. The original notebook can be found in the GitHub repository here …

You can do something like this numpy - Plot Square Wave in Python - Stack Overflow and then pass the square wave to the input_buffer.
