Introduction

The “double tap” is a gesture that today is a crucial part of many of our daily actions.

The goal of this article is to implement a double tap feature that is easy to integrate, intuitive and adaptible.

So, the first step towards this goal is to make sure we have all the materials to develop and test the algorithm. We will use the X-NUCLEO-IKS01A2 board, that is easy to use and install on PYNQ.

Vivado design

The next step is to create an appropriate design for communication with the X-NUCLEO-IKS01A2; in fact you can

Introduction

Have you heard the news about the VCK5000 development card being on discount? We are here with a small tutorial on how to get started and use this board for your future projects.

Xilinx provides scripts which are really useful on installing the principal packages required. However, sometimes someone can run into errors that have no answer anywhere online. Therefore, the aim of this article is to help anyone having troubles setting up the VCK500. Moreover, as an extra, we have a special section on how to reduce the loud noise

Introduction

FPGA programming is not only based on a hardware design, you also can also create software that runs on different soft processors on it, called “MicroBlaze”. This kind of design is useful in specific applications, such as protocol implementation, system orchestration, and soft-realtime systems.

The aim of this article is to reproduce a little architecture that supports this soft processor, controlling a simple peripheral such as a GPIO, using the PYNQ framework for instantiation and controlling.

What is a MicroBlaze

The MicroBlaze IP describes a soft microprocessor, that is a microprocessor core completely

Introduction

PYNQ is a perfect framework for beginners and advanced users of FPGA,  it provides a great base bitstream that manages some peripherals on the board without any effort. However, if you need custom IPs for your application (and also for custom pinout), you need to know how to create a specific bitstream using the Xilinx IP Cores, which are quite documented but not often ready to use. In this article, we can show you how to implement a design that can output multiple PWM signals on the PMOD of a

Introduction

This article shows how to create a PYNQ-DPU application on CorazonAI with the acceleration of the whole AI pipeline flow for video analytics . Specifically this article is a follow-up of the previous article on CorazonAI which can be found here: https://www.makarenalabs.com/pynq-on-corazon-ai-ai-applications-for-all/

AI pipeline and PYNQ

PYNQ is a framework which allows us to use python bindings on the FPGA.

However, having the bindings for python, doesn’t necessarily just mean the possibility of working very easily with our custom IP cores.

In fact, python is a gold standard programming language in computer science and

Introduction

The Corazon-AI board from iWave is very interesting: it has everything you need for an embedded vision application. In the AI world, the time-to-market parameter is very important for a winning application; also currently there is fierce competition, also against the real competitor of the FPGA, the GPU. So we choose to integrate on the Corazon-AI the best ally: the PYNQ framework. PYNQ gives to you the right instruments to create a product-ready application, Python based. You will find a simple tutorial for building the PYNQ framework for the Corazon-AI

Introduction

In recent days the creation of various web-based application with AI implied the choice of using a cloud architecture This structure can be achieved by creating a REST-API like architecture. The generic structure of this process is the following:

There are sensors (i.e. a camera) which create information;
Secondly cloud receives the information from the collector;
Then cloud performs the AI tasks and return results;
Finally sender uses the results of the inference for its purposes.

However, previous proposed web-based application system has three drawbacks:

First, it needs an high speed internet connection (with its highly

Introduction

Content sharing in the web world is primarily provided by WordPress, an open-source Content Management System (CMS from now on) written in PHP language. For this reason, it is very important to master the software installation. So, the aid of IT automation and its tools (like Ansible) is really important, because in this way you can easily install and manage the software.

One of these softwares is Ansible, which is an IT automation engine that automates configuration deployments, cloud provisioning, application deployment, and other IT needs. It offers a simple framework

There are two methods for using devices on FPGA for PYNQ: the integrated microprocessor (PS side) and the programmable logic (PL side). In order to maximize the use of the FPGA, this article shows how you can use the programmable logic for common devices such as SPI, I2C and UART.

We have used this flow also for SMART-IO Project. If you have lost the article about SMART-IO, follow this link!

You can find every design in this article as Github project in the MakarenaLabs Github company.

Introduction

In this article about shared memory, we are going to show in broad terms how two different programming languages, such as JavaScript and C++, can interact with each other. Specifically, we are going to introduce the concept of shared memory and illustrate an example in which two processes interact through this data exchange system.
In the first part we will give some useful definitions to better understand what we are going to explain later in the second part, in which we present some examples of commented code.

the Shared memory

The concept of
