Hi there,

anyone can help me to solve the problem regarding the uploading program into arduino board? I'm using arduno duemilanove. At first I upload a program into the arduino board, and its work. Then I want to upload a new program, but it will appear "serial port already in use, try to quiting any program that may be using it". Therefore, what should I do to quit the program inorder to upload a new program?

We have yet to see this in our RnD lab. What is the OS you are using? It might have something to do with the OS.

You can try looking through the thread under Arduino forum here. Hope it helps.

thanks for the reply, i'm using windows 7.
