"Serial port in use" is on the PC side, not the Leonardo's side.If you load Blink on the Leonardo and keep trying to reload it, do you still get the serial port in use?Quote from: hilukasz on Dec 12, 2013, 04:41 pm2. this suggestion http://www.baldengineer.com/blog/2012/10/08/arduino-fixing-serial-port-in-use/Yeah, I wrote that with the Uno and Mega in mind. The Leonardo is different. Although, it would be good to use lsof to find out what is holding the port open (something has to be).
nope, like i mentioned earlier, it only happens when I have serial communication it seems, simple sketches like blink don't seem to have an affect.
