Ich lese Daten von der seriellen Schnittstelle für durchschnittliche Intervall sagen 1 Sekunde, und zur gleichen Zeit schreiben Daten in TextArea und Textdatei, Problem ist, ich bekomme nicht die richtigen Daten zu einer bestimmten Zeit, kann sein, weil ich alle drei Prozesse in einem einzigen Programm mache, wie schreibe ich Textbereiche und Textdateien durch separate thred?Threads zum Lesen und Schreiben von Java
dies ist mein Code:
