Framework PON Micropython 1.0: paradigma orientado a notificações para microcontroladores

Abstract

The Notification-Oriented Paradigm (NOP) emerges as an innovative solution to overcome recurring limitations in traditional programming paradigms, such as code redundancy and high coupling. The realization of NOP concepts has been achieved through state-of-the-art frameworks and the state-of-the-art LingPON Technology. This work presents the development of the PON MicroPython 1.0 Framework, specifically designed for microcontrollers compatible with the MicroPython interpreter. During the development process, priority was given to integrating NOP elements with the most common peripherals in microcontrollers, such as General-Purpose Input-Output (GPIO), Analog-to-Digital Converter (ADC) and Pulse Width Modulation (PWM), in addition to a modular mechanism for notification communication between different devices. This communication is facilitated by communication drivers that maintain a high-level programming interface, ensuring usability and flexibility. The results include the development of two practical applications to validate the framework. The first application aims to evaluate the cost of integrating peripherals with NOP elements, both locally and distributed between two microcontrollers. The second application, named Air Quality Monitor, explores the framework’s potential in simplifying the distribution of notifications in a more complex scenario involving four microcontrollers and two distinct communication drivers. Both applications demonstrated that the framework streamlined development, reducing the size of the final code while maintaining a high-level programming interface. However, the results also highlighted an increase in latency between actions and in RAM consumption, stemming from the structures used by the framework to provide NOP component abstractions. Additionally, this work details the use of the framework elements, encompassing both those integrated with peripherals and the communication drivers developed. The documentation provided establishes a solid foundation for other developers to adopt and expand the use of the framework in various contexts. Finally, future improvements for the PON MicroPython 1.0 Framework are proposed, focusing on enhancing the communication mechanism.
