Hallo,
möchte mir ein kleines Interface für den PC sowie für das Smartphone entwickeln. Der Arduino wird über den HC-05 angesteuert.
Ich möchte nicht ständig alle Daten zum Arduino schicken, habe mich somit für eine einfache Kodierung basierend auf Hexzahlen entschieden.
Jeder Regler schickt nun seinen Wert (0-255) an den Arduino wie folgt. 0x(ID(0-F)(Wert(0-FF).
Für einen Wert von 127 für den ersten Regler würde das wie folgt dann im Arduino gehandhabt:
0x07F
Für einen Wert von 255 für den zweiten Regler würde das wie folgt aussehen:
0x1FF
....
Habe nun das Problem, dass die Eingabe über Putty nicht der entsprechenden Auswertung entspricht.
