arduino permission denied
When using windows programs on linux there are always permission problems... and most often they are really simple to fix :)
When getting a:
Method name - openPort(); Exception type - Permission denied.
error while trying to upload programs the simple fix is to add the user to the dialout group like that:
sudo adduser username dialout
important:
After doing this you have to logout and login again to take effect of the changes!!!
hint:
I read about people still having problems with some ports. An ugly fix for that would be the editing of file-permission rights.
sudo chmod a+rw theport #sth. like /dev/ttyACM0
