Do you know the project MyOpenLab?MyOpenLab uses dll to k8055 of Velleman.The author has also integrated Arduino (and Arduclema) libraries using serial communication.It may be interesting to create a dll to be used by MyOpenLab. You can also comment on the forums of the project MyOpenLab.We also want to program graphically Arduino (and Arduclemas;)) from MyOpenLab through Java.Greetings.cOLe.
