I realize that in Ubuntu 14.04 and when I want to compile in the arduino sketch I get this little error
avrdude: ser_open(): can't open device "/dev/ttyACM0":
Permission denied ioctl("TIOCMGET"):
Inappropriate ioctl for deviceTo fix this we do the following:
sudo usermod -a -G dialout $USER (1)
sudo chmod a+rw /dev/ttyACM0 (2)| 1 | Add our user to the dialout group |
| 2 | Permissions to all users thanks to parameter a, plus read(r) and write(w) for port ttyACM0 |
then reboot and it should work.
