Remote control HA

Publicat de Florin pe ianuarie 26, 2026ianuarie 26, 2026

Am folosit un esp32 LVGL cu touch de 2.2

si am incepu sa scriu un cod :

in care avem conectare wifi , conectare mqtt . avem librarille lovyanLVGX , si cele pentru touch ,am studiat disply ul este un ST conectat paralel , si am identificat pinii . mai jos aveti codul unde puteti schimba , credentiale wifi si mqtt dar comenzile mqtt trebuie sa le gasiti nu se vor poreivi cu ce am eu ,
