Sistema de controle de iluminação cênica utilizando o protocolo sACN E1.31

Abstract

Over the past decades, lighting systems have undergone notable transformations to reach their current stage. From old incandescent bulbs to the most modern LED technologies, the changes have been market not only by the pursuit of energy efficiency but also by the growing appreciation for aesthetics. The transitions to LED technologies further highlight the relevance of Internet of Things systems, which seek to bring convenience and consistency in communication among various electronic devices, including those dedicated to lighting. This work addresses the implementation of communication protocols for lighting, such as Streaming CAN and WS2812, with the aim of creating a system capable of updating a set of RGB LEDs in real-time with consistent data transmission rates, using an ESP32-C3 microcontroller to generate activation signals through the I2S serial protocol. The work includes a prototype that was examined with the assistance of signal measurement instruments for verification and evaluation of the results obtained. The created system demonstrated consistency in data transfer, meeting the temporal protocol requirements necessary to create a dynamic lighting system.
