Objective: Investigate the reliability of the UDP CRC field on an ESP32 when transmitting Modbus packets over UDP. Methodology: A sender script on a Linux device (e.g., Raspberry Pi) is used to send ...

This project implements a simple yet efficient UDP-based image streaming system using an ESP32-CAM module and a Python server. The ESP32 captures frames from its onboard camera and streams raw YUV422 ...

We just got our hands on some engineering pre-samples of the ESP32-C3 chip and modules, and there’s a lot to like about this chip. The question is what should you compare this to; is it more an ESP32 ...

Using PlatformIO with Visual Studio Code offers a powerful, flexible, and easy-to-use environment for microcontroller firmware development. This article describes an example of integrating PlatformIO ...

Often, reprogramming a microcontroller involves placing it in reset, flashing the code, and letting it fire back up. It usually involves shutting the chip down entirely. However, [bor0] has built a ...

Waveshare ESP32-P4-NANO is the first third-party ESP32-P4 RISC-V board we’ve seen and it follows the launch of the Espressif Systems’ ESP32-P4-Function-EV-Board devkit introduced this summer. While ...

This ESP32 project is an exciting and interactive way to control LEDs using hand gestures. We will use an ESP32 board, Python, MediaPipe, and OpenCV to create a system that can detect specific hand ...

Want instant SMS alerts from your ESP32 without relying on a bulky GSM module? Whether it's motion detection, a sudden temperature spike, or an unauthorized locker door opening, your ESP32 can now ...

ESP32 microcontrollers, known for their versatility in IoT and smart home projects, also support digital audio via their I2S interface. In the first part of this series, we explore an audio-focused ...
