Hallo zusammen,
ich war am WE fleissig und habe mich speziell mit der Datenübertragung vom Nextion beschäftigt. Mein spezielles Problem konnte ich lösen. Die Schalter und Slider bekomme ich nun korrekt geliefert und ich kann den eigentlichen Code weitertreiben.
@Thommy: die Arbeitsweise vom Nextion war mir schon klar, einzig der Simulator hat mich ins Schleudern gebracht, weil er zwei einzelne Zeilen, 1x die 0x65 und 1x die 0x71 lieferte. Da hatte ich keine Idee dazu, wie man es verknüpft.
Dass es ein einziger Stream ist und bleibt, habe ich erst später erkannt.
Danke an alle Helfer, das hätte ich alleine nie geschafft.
Nachfolgend der ungepflegte Code, wie ich es auf die Schnelle gelöst habe. Vielleicht hilft es jemandem weiter.
Gruß und Dank, Franz

// - Slider:
// im ReleaseEvent die SendID aktivieren, und im MoveEvent noch die
// Weiterreichung auf das Nummernfeld einstellen.
// so wird beim Loslassen des Schiebers der letzte Wert mit
// 'get Slider1.val' über die Schnittstelle gesendet,
// Antwort: 71 64 00 00 00 FF FF FF (dez.Wert=100)
// 65 01 01 00 FF FF FF -> wegen TouchEvent
