Bei dem Versuch, die Statemachine zu umgehen, habe ich mir für die OLED-Anzeigen nun nach etwas Tüftelei folgendes ausgedacht (Wasserfluss-Interrupt aus Gründen der Übersichtlichkeit temporär herausgenommen):
// OLED Test-Sketch without delay on ESP32 Devkit v1
#define MIN_LOOP_DELAY 900
#define SCREEN_MILLISECONDS 50
float serialInterval = 30000; // Einmal alle 30 Sekunden = 30000ms
unsigned long oldSerialTime; // Timer for serial-prints
float oledInterval = 2500; // Einmal alle 2,5 Sekunden = 2500ms
unsigned long oldOledTime; // Timer for OLEDs
byte oledChange;
unsigned long resetLoops;

}
Um die schnell zunehmenden Loops auszubremsen, verwende ich MIN_LOOP_DELAY mit z.B. 900ms Zeitverzögerung: Wenn die Loops und aktive Schaltungen gezählt werden und als Rechengrundlage für den Prozentsatz der aktiven Laufzeit herangezogen wird, müssen die Variablen entsprechend in der Lage sein, die hohe Anzahl der Durchläufe auch aufnehmen zu können.
Kann das obige Beispiel mit festen Zeitfenstern für Serial.prints und den OLED-Anzeigen optimiert werden?
