📌 Descripción del Pull Request
Este PR agrega mi investigación individual sobre el protocolo Modbus RTU sobre RS-485 en sistemas embebidos. Explica la capa física RS-485, la estructura de las tramas Modbus RTU (CRC-16, tiempos t1.5 y t3.5, funciones y excepciones), aspectos de implementación en microcontroladores (control DE/RE) y un análisis crítico frente a otras alternativas.
