<div class="markdown_content"><p>Hallo,</p> <p>ich möchte Timer mit "Neustart" realisieren. Wenn die Taste "START" betätigt worden ist, läuft die Zeit z.B. 30 Sec. Wenn die Taste "START" noch betätigt worden ist, dann sofort einen neuen Start für Timer( egal 30 Sec. ist vorbei oder nicht). </p> <p>Wie kann ich diese Aufgabe in FUP oder ST realisieren? </p> <p>Danke schön im Voraus!</p></div>
