TinyML in Action: Building a bird detector that fits in the palm of your hand

In recent years, artificial intelligence in microcontrollers (TinyML) has gone from being a laboratory curiosity to becoming a real tool for environmental monitoring, health, and industrial automation. This article shows how we transformed gigabytes of raw audio—the songs of six Patagonian species—into a fully INT8-quantized model that takes up just 60 kB of Flash and takes less than a second to classify a clip on an ESP32.

Zephyr OS, A brief introduction

The Zephyr Project emerged on the embedded systems scene in 2016 as a new real-time operating system (RTOS) for embedded and IoT devices. It's a collaborative effort led by the Linux Foundation, along with Wind River, Synopsys, and NXP. Their goal was to create a multi-platform RTOS that leverages proven concepts from the Linux operating system, such as kconfig, device trees, and the driver model.‍

Qt Development: Challenges and Strategies for Efficient Code Inheritance

Developing software based on preexisting code is an art in itself. When this challenge is combined with the use of the Qt framework and an inefficient legacy architecture, the complexity and opportunities multiply. In this blog, we will explore not only the benefits and challenges of inheriting code in the world of Qt but also how to address an inefficient legacy architecture and face the eternal dilemma of investing time in redesign versus saving time by maintaining the existing architecture.

Integrate an OPC UA Server into an embedded or PC application using the QT platform

In today's post we will introduce you to automating industrial or Internet of Things equipment through an API developed with the OPC UA standard using QT as a development platform. QT allows you to create cross-platform applications, so you could create an application that runs both on a PC and on an embedded system like a raspberry pi.
