Firmware is a specific class of computer software that provides the low-level control for a device’s specific hardware. Firmware, such as the BIOS of a personal computer, may contain basic functions of a device, and may provide hardware abstraction services to higher-level software such as operating systems. For less complex devices, firmware may act as the device’s complete operating system, performing all control, monitoring and data manipulation functions. Typical examples of devices containing firmware are embedded systems, home and personal-use appliances, computers, and computer peripherals.
Unlock the potential of wireless Arduino UNO programming with DT-06 and ESP-Link Firmware. Our guide explores the seamless integration of WiFi and serial communication, transcending the DT-06’s original firmware limitations, and upgrading remote device management in the IoT domain
The SunFounder Zeus Car Smart Car Kit for Arduino UNO is an educational kit designed for beginners and children to gain hands-on experience in electronics, robotics, and programming.
It’s very fun to upgrade and programming with It.
In this article we are going to apply two upgrade: light and WiFi boost.
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.
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.
Welcome to the final article in our ESP32 firmware and OTA update management series. Today, we’ll explore using an FTP client to update the firmware and filesystem on an ESP32 device. Join us as we delve into this last technique, equipping you with valuable insights for managing updates on your ESP32 projects.
In this article, we explore a non-standard but effective method for updating ESP32 firmware and filesystem using an SD card. We’ll discuss the advantages, disadvantages, and provide a step-by-step guide for implementing this technique, building on knowledge from previous articles in our firmware management series.
We are going to continue exploring OTA updates. In this article, we delve into secure self OTA updates for ESP32 devices using HTTPS (SSL/TLS) with trusted self-signed certificates. Learn how to generate certificates, set up the ESP32, and configure the update server for enhanced security and efficiency in your IoT projects.
In this article, we’ll explore an efficient method for implementing self Over-the-Air (OTA) firmware updates for the ESP32 microcontroller, complete with version checking. This approach enables IoT devices to automatically download and install the latest updates from a server, ensuring a resilient and adaptable IoT ecosystem without requiring manual intervention.
This article discusses how the ESP32 can perform self-OTA updates of its firmware from a server, allowing you to remotely update the firmware of an ESP32-based device without having to physically access the device. To do this, you need to set up a server that hosts the new firmware image and add OTA support to your ESP32 firmware. By implementing self-OTA updates, you can ensure your devices are running the latest firmware without having to physically access them.
This tutorial explores how to implement OTA updates on an ESP32 using a web browser as a custom interface. We will create a custom web interface using HTML and JavaScript to upload firmware files to the ESP32, and then use the ESP32’s OTA update feature to install the new firmware. By the end of this tutorial, you should have a solid understanding of how to use OTA updates to keep your ESP32 devices up-to-date with the latest firmware.
