Hallo werte MattzoController Freunde
Ich habe folgendes Problem:
Wenn ich einen Geschwindigkeitswert über RocRail an den MattzoController sende, wird dieser auch über dem MQTT Broker übertragen. Hier ein kleiner Auszug aus dem SerialMonitor:
Setting train speed 30 (power: 634) for motor shield index 0
setMotorShieldPower() called with msi=0, mpi=0, desiredPower=-634
Setting train speed 35 (power: 673) for motor shield index 0
setMotorShieldPower() called with msi=0, mpi=0, desiredPower=-673
Setting train speed 40 (power: 712) for motor shield index 0
setMotorShieldPower() called with msi=0, mpi=0, desiredPower=-712An den PIN D3 und D4 wird aber immer ein Spannung von 3.28V ausgegeben. Jeder Geschwindigkeitsveränderung in RocRail wird an den PIN D3 und D4 nicht ausgegeben.
Somit resultiert bei jedem Geschwindigkeitsbefehl eine Spannung von 8.8V auf dem Motorshield.Hier die Config im Controller:

P.S.:
Motorshield habe ich bereits gewechselt. Habe aber den Controller noch nicht durch einen anderen ersetzt. -
Wenn ich Dich richtig verstehe, klappt anhalten und fahren grundsätzlich, aber beim fahren fährt die Lok immer mit voller Leistung, korrekt? Wenn dem so ist, würde ich Dir empfehlen, mal mit folgenden beiden Parametern zu spielen:
.minArduinoPower = MIN_ARDUINO_POWER,
.maxArduinoPower = MAX_ARDUINO_POWER,Probier doch mal
.minArduinoPower = 200,
.maxArduinoPower = 500,oder so etwas, und teste ein bisschen was für die Lok gut funktioniert.

Hallo Matthias
Danke dir für den Tipp, genau dies musste ich im Code anpassen. Die zugewiesenen Werte zu .minAurduinoPower und .maxArduinoPower sind zu hoch.
Ich musste die werte wie folgt anpassen damit ein brauchbares PWM Signal generiert wird:
.minArduinoPower = 1,
.maxArduinoPower = 300,Ein Wert von 400 wird im main.cpp der Funktion .minArduinoPower zugewiesen.
Dieser Wert führt dazu, dass das PWM Signal an den Ausgänge D3/D4 eine gemittelte Spannung von ca. 3.3V erzeugen.Warum dies nun bei diesem Microcontroller von AZ-Delivery so ist, kann ich nicht sagen.
Gemäss Lieferant ist der gelieferte Microcontroller der gleiche, wie der in der Materialliste auf Mattzobricks.com.Sei es so wie es ist aber nun funktioniert alles so wie es soll.
Danke dir und bis bald
