I want a python interface where I can input some sequence of bits and it should go to the fpga board. The data needs to be inputted to a custom IP. What are the steps required to do this? ---

Hello and welcome to the community of PYNQ =] The easiest and lowest effort way is to use GPIO as bytes or words load and capture via some logic. And a simplest ready and busy logic to indicate it is go or no go. Other than that you need more knowledge on HDL design and HLS. ---

Video example that may be of use here; using PS GPIO: [![](https://us1.discourse-cdn.com/flex019/uploads/pynq1/original/2X/6/62d755ac97eeb48658407002374725120642d78b.jpeg "PYNQ Tutorial; PS GPIO Part 1: building the hardware") ](https://www.youtube.com/watch?v=a5NnLozPEI0) There are other ways to do this depending on what you need, and your IP.

This is similar to what I want, except that the data I want to transfer is more than 64 bits (136 bits, to be precise). How can that be achieved? ---

Hello, could you please elaborate on how this supposed to be done. My design requires a 136-bit input which I want to be given from python code and the rest of the pins of my design will be mapped to the peripherals of the board. I have attached a picture of my design. ![image](https://us1.discourse-cdn.com/flex019/uploads/pynq1/original/2X/4/49f19a92698671b82bcb12e304abededd4300150.png) ---

[https://pynq.readthedocs.io/en/v2.7.0/overlay\_design\_methodology/overlay\_tutorial.html](https://pynq.readthedocs.io/en/v2.7.0/overlay_design_methodology/overlay_tutorial.html) I saw this tutorial and it is similar to what I want, besides that I want to input an array. One thing though is that the design in the tutorial has an AXILITE interface whereas my IP does not. Do I convert my IP to have an AXILITE interface, as that seems to be very cumbersome? Or is there any other method which I should follow?
