Uniot Core is the heartbeat of the Uniot platform, designed to seamlessly power IoT devices. As a highly optimized open source operating system, it serves as a crucial component, enabling efficient task scheduling, networking, storage management, and more. With its own script sandbox, Uniot Core allows secure and fast direct execution of scripts directly on the device.
Currently, Uniot Core is optimized for ESP8266 microcontrollers, with plans to extend support to ESP32 controllers. The decision to base Uniot Core on the Arduino framework and implement it in C++ is rooted in a commitment to accessibility, performance, and community collaboration. Arduino's user-friendly nature, coupled with the efficiency of C++, enables developers to create and scale applications with ease. The platform also benefits from a vast ecosystem of existing libraries and a thriving developer community.
Uniot Core, the backbone of your IoT solutions, uses PlatformIO to organize the project. This structure consists of C++ classes grouped into logical modules, providing a foundation that makes it scalable, easy to understand, and efficient to manage.
Uniot Core employs PlatformIO, an open source ecosystem for IoT development, to manage the project's environment. This includes dependency management, streamlined build processes, and integration with various IDEs, ensuring a smooth development experience.
