Bluetooth Display - Teil 5

Willkommen zu dem fünften und vorletzten Teil der Bluetooth Display Reihe. In dem heutigen Teil habe ich mir etwas besonderes einfallen lassen. Die Idee kam mir bei einem Flohmarkt, bei den ich ein paar alte Sachen verkaufen wollte. Ich überlegte mir, dass es doch eine gute Idee wäre das Display nicht zuhause verwenden zu können, sondern dass das Display auch als „Eye Catcher“ bei einem Flohmarkt zu verwenden. Schließlich hat nicht jeder so etwas, und im regulären Handel habe ich ein ähnliches Display auch nicht gefunden. Doch was soll ich auf dem Display bei einem Flohmarkt anzeigen? Am besten einen Verkaufsticker! Wie wäre es mit Botschaften wie: Jede CD nur xx Euro, gefolgt von einer weiteren Nachricht wie: Jede DVD xx Euro. Das Ganze sieht natürlich am besten als Ticker Laufschrift aus, daher bauen sich langsam die einzelnen Buchstaben von linke nach rechts auf, bis die ganze Nachricht lesbar ist. Für jeden Flohmarkt ein totaler Hingucker! Um diese Funktion zu realisieren erweitern wir nun unseren Code um die „Advertising“ Funktion. Wir laden daher zuerst den um die Funktion „Advertising“ erweiterten Code auf unsere Hardwareplattform hoch: #include #include #include #include #include #include #define MaxInputBufferSize 20 // maximal 255 Zeichen anpassen an vlcdr #define EEpromSize 990 #define rLcdChr 20 #define LcdRows 4 #define interval 1000 #define BackgroundLight 5 // Port 5 Hintergrundbeleuchtung LED #define SwitchPin 2 // Port 12 Taster Nachrichtsauswahl // EEprom SpeicherzellenAdressen für Konfiguration #define EEFadeSeconds 993 #define EEAdvertsecdelay 994 #define EEAdvertMsg 995 #define EEPINA 996 #define EEPINC 997 #define EEPINDD 998 SoftwareSerial mySerial(7, 6);

Diese zeigt unser Menü unter „Other“ an: Als Handyapp empfehle ich zur Bedienung die App „BlueTerm“ die es kostenlos aus dem Google Store zu laden gibt. Um nun die Nachrichten nacheinander automatisch anzeigen zu lassen, ist wie folgt vorzugehen: Als erstes setzen wir mit dem Befehl ADMSG die Anzahl an Nachrichten von 0 zählend, die nacheinander angezeigt werden sollen. Beispiel: Wir haben in den Bänken 0-2 insges. 3 Nachrichten gespeichert, die angezeigt werden sollen. Dann geben wir nach dem Befehl ADMSG die Zahl 4 ein. Als Quittierung bekommen wir die Ausgabe: „Value 2 set“. Danach geben wir den Befehl „ADSEC“ ein gefolgt von einer Zahl zwischen 1 und 255. Dabei steht die eingegebene Zahl für die Anzahl an Sekunden, bis die angezeigte aktuelle Nachricht durch die nächste konfigurierte Nachricht ersetzt wird. Als Beispiel geben wir hier „5“ ein. Als Quittierung bekommen wir auch hier wieder die Ausgabe: „Value 5 set“. Als letzten Schritt geben wir nun den Befehl „ADVERT“ ein. Nach der Quittierung des Befehls durch „Advertising On“ wird nun immer im Wechsel automatisch die Nachrichten aus den Bänken 0-2 hintereinander anzeigt. Ausschalten lässt sich die Automatik durch erneute Eingabe des Befehls ADVERT oder durch einen druck auf den Nachrichtenwahltaster. Ich wünsche viel Spaß beim Nachbauen und wie immer bis zum nächsten Mal.
