Electronic, 3D printing and embedded programming
Wireless sensor nodes are revolutionizing connectivity by collecting and transmitting real-time data. These small, battery-powered devices transform industries like agriculture and healthcare, promising enhanced efficiency, scalability, and a smarter, more connected future.
But which ones to choose
This article shows how to build a simple weather station using an ESP32 and a 4.2″ SSD1683 eInk display, powered by the GxEPD2 library and the OpenWeatherMap API. A low-power project that displays real-time temperature, humidity, wind, and pressure.
Continuing our previous tutorial on configuring the ESP32 SSD1683 display and wiring, this article dives into text and shape rendering, demonstrating font scaling with setTextSize(), custom GFX fonts via setFont(), and drawing lines, rectangles, circles and rounded shapes. We’ll also cover converting images to 1-bit byte arrays with the online generator and displaying them on the E-Ink screen.
ePaper displays offer ultra-low power consumption and paper-like readability, perfect for battery-powered and outdoor devices. The SSD1683 controller handles timing, waveforms, and pixel updates for crisp, ghost-free images. Learn how to connect an SSD1683 panel to an ESP32 with GxEPD, configure SPI, set display parameters, and perform full or partial updates on a CrowPanel 4.2″ HMI also.
This comprehensive guide explains how to use an ILI9341 TFT display with the optimized TFT_eSPI library on ESP32 and similar boards. It covers wiring, library installation, configuration, and provides detailed code examples for drawing shapes, text, images, animations, and troubleshooting. It also outlines next steps, including touchscreen integration and advanced display features. Learn to customize your projects.
In this article, we will dive into some technical details of the Ebyte LoRa E32 module integrated with the STM32 microcontroller. One key feature that we will explore is the WOR (Wake on Radio), which is a significant factor in the world of low-power long-range communication systems.
Microcontrollers, the core of many embedded systems, have evolved from being programmed with low-level languages like Assembly or C to more accessible high-level languages like Python. MicroPython, a streamlined Python 3 implementation, is a prime example. This article explores the integration of MicroPython with the cost-effective, high-potential STM32F4 microcontroller from STMicroelectronics, with a focus on the WeAct STM32F411CE, STM32F401CC, and Nucleo board.
Here an article that provides a step-by-step guide for getting started with MicroPython development on the ESP8266 and ESP32 boards using the Thonny IDE. The article covers how to flash MicroPython firmware onto the board and how to connect to the board using Thonny’s MicroPython plugin. Additionally, the article includes an example project that demonstrates how to control an LED connected to the board using MicroPython code.
This guide focuses on using MicroPython with ESP8266 and ESP32 microcontrollers, two popular choices for IoT and embedded systems. By understanding the standard instruments available with MicroPython, such as Python, esptool, ampy, PuTTY, and screen, you can quickly and easily build projects for these powerful devices. This guide will provide an overview of each tool and how to use them effectively, so you can take full advantage of the capabilities of your ESP8266 or ESP32 microcontroller.
It’s time to explore the new series of microcontrollers based on the rp2040 chip from the Raspberry Pi Foundation. As usual, we are going to use a generic Arduino IDE and C language.
