K8055 USB Interface - Teil 1
von Plapperkatze am 10.Juli 2006 um 21:25
zurück zur Kategorie "Tutorials"

Für Besitzer eines K8055 Boards von Vellemann (erhältlich bei Conrad Elektronik) http://www.velleman.be/product/view/?lan~~2?3~~id=351346 hier eine Zusammenfassung meiner Ergebnisse, Teil 1



Ich bin nicht schuld, wenn ihr euer Board kaputtmacht. Ihr handelt auf eigene Verantwortung.

Als großes Manko erscheint mir die Benutzung der K8055D.dll, der mitgelieferten Treiber-Bibliothek. Einstweilen werde ich sie aber verwenden.

Ich habe eine kleine Test-Schaltung mit dem Operationsverstärker LM318 aufgebaut:


Die Ausgabe auf dem primitiven Oszilloskop sieht etwa so aus:
