Hallo Ihr Lieben,
ich habe das Problem mit meinem Programm, das nach ein paar Stunden Laufzeit immer komische Symbolketten auf dem Display angezeigt werden. Nach einem Neustart läuft alles wieder ganz normal.
Hiermal der Code.
#include "EspMQTTClient.h"

#include <Wire.h>
#include <LiquidCrystal_I2C.h>

Kann jemand einen Fehler entdecken?
