Hallo liebe Leute!! Ich möchte nun ein kleines Programm in Visual Basic 2005 express schreiben, welches die COM3-Schnittstelle liest (von meinem µC gesendet, Baudrate 9600, 8 Datenbits, keine Parität, 1 Stoppbit), und diese Daten in ein Label/TextBox schreiben soll. Könntet ihr mir helfen? Habe kaum Ahnung von Visual Basic 2005. Vielen Dank!
Wie waere es die Suche zu bedienen?
