ESP32 - Creating a WiFi Driver with ESP-IDF - Shawn Hymel
One of the biggest selling points of the ESP32 is its integrated Wi-Fi hardware and software stack. In this tutorial, you'll learn how to create a robust| Shawn Hymel
Edge AI refers to artificial intelligence that runs directly on devices at the “edge” of the network: things like smartphones, smart cameras, industrial sensors, autonomous vehicles, and IoT devices. Instead of sending data to remote servers for processing, edge AI performs inference and decision-making locally on the device itself. This architecture delivers crucial advantages: reduced […]| Shawn Hymel

A few years ago, James Provost built a handheld texting device, based on Arduino, to send short messages over a connected ham radio set. One of my many backburner projects has been to build something similar, either based on amateur radio (like James’s project) or based on LoRa. Little did I know that Kevin Hester, […]| Shawn Hymel

The global robotics market is projected to reach USD 178.7 Billion by 2033. The complexity of creating intelligent machines is growing exponentially, including the new emerging field of embodied AI. Developers face the daunting task of integrating sensors, actuators, navigation, manipulation, and machine intelligence into a cohesive system. Building these intricate software stacks from the […]| Shawn Hymel
When you’re building projects with ESP-IDF, you’ll quickly notice just how many libraries, drivers, and middleware options are available. From Wi-Fi and Bluetooth stacks to peripheral drivers and logging systems, the sheer number of options can feel overwhelming. Manually editing header files or juggling different CMakeLists.txt entries just to try out a new feature gets […]| Shawn Hymel
The world of embedded systems seems to be composed of two types of developers: those who love real-time operating systems (RTOSs) and those that despise them,| Shawn Hymel
In the previous tutorial, we looked at getting started with ESP-IDF and created our first blinking LED project for the ESP32. The next step to effectively using ESP-IDF is to understand a little about CMake, which is the build system generator commonly used for low-level languages, like C/C++, for operating system and embedded system development. […]| Shawn Hymel
If you're a student exploring embedded systems or a professional developer looking to transition into the embedded side of IoT, building a personal project is| Shawn Hymel
This tutorial will walk you through the process of setting up ESP-IDF using a Docker container and build a basic blinking LED example from this repository: https://github.com/ShawnHymel/course-iot-with-esp-idf/. Here is a video version of the guide: Why ESP-IDF? The Espressif IoT Development Framework (ESP-IDF) is the official software development kit for the ESP32 family of microcontrollers.
