I keep trying to upload a new example in the sketchbook to my decimilla, but it keeps saying at the bottom of the window "serial port… already in use. Try quitting any programs that may be using it.
I quit all the programs I am using and still nothing. The board is linked by a-b usb 2 cable.
I have managed to upload examples before (i.e. blink) and its still blinking but today it decided not to upload.
Anone know why?
