Light Cube using PYNQ

PYNQ Light Cube

Brief Introduction

This repo shows how to write a controller in python to control peripherals connected to FPGA. We can write any peripheral drivers in FPGA to achieve real-time high speed signal processing. Thanks to PYNQ platform, we can easily wrapper the FPGA drivers into simple python code.

• Introduction to lightcube on pynq and slides
• Demo video
• Run playground.ipynb
• Click webpage to control single LED
• Run pre-defined patterns

Get Started

Based on PYNQ Image 2.0

1. Clone this repo on PYNQ board: git clone https://github.com/sonnyhcl/PYNQ-Light-Cube.git

2. Run the setup bash script to setup lightcube: bash PYNQ-Light-Cube/setup.sh

3. Open your browser with <pynq_ip>:9090 and type in xilinx as password.

4. Get started using LightCube_GetStated notebook.

5. Find LightCube_Playground notebook and run. Then you can turn into <pynq_ip>:8080 to view a webpage displaying real-time status of lightcube.

tips: <pynq_ip> is the ip of your pynq.

Repository Organisation

This repository is organized as follows.

• hw contains constraints source file, custom ip, and tcl file to rebuild whole hardware design.

• notebook contains lightcube controller in python, webserver resources, and notebook for playing.

• overlay contains bit and tcl file of hardware design, and py to import overlay.

• setup.sh helps setting up this lightcube package.

Hardware Design Rebuilt

In order to rebuild this hardware design, you should clone this repo in a machine installed with Vivado 2016.1(only tested with Vivado 2016.1).

1. Clone this repo: git clone https://github.com/sonnyhcl/PYNQ-Light-Cube.git

2. Change your work directory: cd hw

3. Make sure you have successfully configure you vivado environments: source build_hw.tcl

4. Wait for a minute and then you can open the new-built projects.

Thanks to John Pan@pjh177787 for his hardware design.

pynq-light-cube's Issues

Hi. I have a question.

I am interested in the PYNQ board and want to control the lightcube.

I want to ask a question about lightcube.

Does it matter what lightcube you can buy on eBay or AliExpress?

I have Led cube for Arduino but this doesn't support usb port.

I'm a low grade electronics student, so I'm sorry for the lack

I really want to answer your questions
