Constructing an STM32 Web Dashboard Utilizing the Mongoose Wizard: A Step-By-Step Guide
Cesanta Software, the creators of the open-source Mongoose Web Server Library and Mongoose OS, have published a guide on building an STM32 web dashboard. This in-depth tutorial provides a step-by-step approach to creating a web-enabled STM32 application featuring real-time dashboard and secure Over-The-Air (OTA) firmware updates.
The development process begins with setting up a development environment. This involves installing Mongoose OS, a framework for IoT firmware development that supports STM32 microcontrollers, and required toolchains like the ARM GCC toolchain and other STM32 development tools. The Mongoose Web Server Library, which provides an efficient HTTP server, is integrated into Mongoose OS.
Once the development environment is prepared, you'll move on to designing the web dashboard using HTML, CSS, and JavaScript, which will run on the STM32 device. The dashboard's web files (HTML, JS, CSS) can be served using Mongoose's embedded web server, which supports REST APIs, WebSocket, and static file serving.
The subsequent step involves integrating these components with Mongoose OS. This includes writing firmware in C or JavaScript for Mongoose OS that controls STM32 peripherals while exposing APIs to the web dashboard. Network connectivity for web dashboard access is also established, and the Mongoose OS API framework is utilized for hardware control and event handling.
One of the most significant features of this web dashboard is the OTA update facility. Mongoose OS supports OTA updates out-of-the-box, enabling authenticated wireless firmware updates via the web dashboard. To implement this, new firmware is built, hosted on a server, and the OTA update process can be triggered from the dashboard.
Before deployment, it's essential to test the dashboard locally, verify OTA updates, and secure the dashboard and updates with HTTPS and authentication. A comprehensive guide by Cesanta Software covers setup, coding examples, and OTA implementation details for building an STM32 web dashboard.
It's worth noting that Cesanta Software previously released a similar guide for their web dashboard for the ESP32, highlighting the STM32 support this time around. Their Mongoose technology line was introduced back in 2017.
Thanks to [Toly] for bringing this guide to our attention. For more details on building STM32 web dashboards using Mongoose OS and its web server library, readers are encouraged to refer to the comprehensive guide provided by Cesanta Software.
In the guide by Cesanta Software, the Mongoose Web Server Library, integrated into Mongoose OS, is employed for building an STM32 web dashboard. This development process also includes setting up a development environment, which requires the installation of Mongoose OS, ARM GCC toolchain, and STM32 development tools, followed by integrating the web dashboard using HTML, CSS, and JavaScript with Mongoose OS.
