Configuração e integração do módulo ESP-8285 com microcontrolador STM32 para comunicação wi-fi de display LCD via interface web local

Abstract

This work aims to develop and validate a communication system between an STM32F103 microcontroller and an ESP8285 Wi-Fi module, using AT commands for device configuration and control. The proposal aims to understand and apply the fundamental concepts of UART serial communication, widely used in embedded systems and Internet of Things (IoT) applications. The project aims to demonstrate that, despite the relevance of Wi-Fi modules in the current connectivity context, the AT command approach is still underexplored in academia. Contemporary projects tend to favor direct internal programming of modules, using prototyping platforms such as Arduino and ESP32 with native SDKs. Therefore, an accessible, documented, and replicable solution is proposed, demonstrating that it is possible to provide Wi-Fi connectivity without the need to reprogram the module’s firmware, using only the UART interface and standardized AT commands.
