Eine elegante automatische Treppenbeleuchtung (Teil5)

Hallo und Willkommen zu dem letzten der Teil der Reihe „elegante automatische Treppenbeleuchtung“.

Heute runden wir unsere Steuerung um eine komfortable Konfigurationsmöglichkeit aller Betriebsparameter ab. Alle Betriebsparameter können nun über die serielle Schnittstelle im Ruhezustand (alle Treppenlichter inaktiv) bequem eingestellt werden und werden im internen EEPROM des uC’s abgespeichert. Somit bleiben alle Einstellungen auch bei einem Neustart oder bei Spannungsausfall erhalten. Alle einstellbaren Parameter werden am Ende des Dokumentes einzeln erklärt. Da die Funktion komplett in Software realisiert ist ändert sich der technische Aufbau um Vergleich zu Teil 4 der Reihe nicht. Trotzdem soll dieser aus Gründen der Vollständigkeit nochmals dargestellt werden:

Auch die Liste der Komponenten für das Projekte und alle Hinweise aus den vorherigen Teilen ändern sich nicht:

Es kann OHNE vorherige Anpassung folgender Code auf den Arduino hochgeladen werden:

#include <Wire.h>
#include <EEPROM.h>

#define PWM_Module_Base_Addr 0x40 // 10000000b  Das letzte Bit des Adressbytes definiert die auszuführende Operation. Bei Einstellung auf logisch 1  0x41 Modul 2 etc.. Adressbereich0x40 - 0x47 
// wird ein Lesevorgang auswählt, während eine logische 0 eine Schreiboperation auswählt.
#define OE_Pin  8                 // Pin für Output Enable 
#define CPU_LED_Pin 13            // Interne Board LED an Pin 13 (zu Debuggingzwecken)

Nachdem der Code hochgeladen wurde, können wir uns mit 9600 Baud auf die serielle Schnittstelle verbinden. Nach einem Enter (und inaktivem! Treppenlicht) erscheint folgendes Konfigurationsmenü:

Ich wünsche viel Spaß beim Nachbau. Wie immer findet Ihr auch alle vorherigen Projekte unter der GitHub Seite https://github.com/kuchto
