Hi,
I cannot upload anything to my arduino because I get an error that the serial port cannot be opened and at first I have a serial port checked in the tool menu but after hitting the uplaod button tools-serialport is just grey.
I am using Fedora 20 and I have just installed it yesterday on my computer and my netbook. On my cmputer everything works fine but not on my netbook.
And I just get this error when I am running with my account which is an administrator but when I am running with sudo it works.
The warning that is displayed in all cases when I start the arduino program with the terminal is:
WARNING: RXTX Version mismatch
Jar version = RXTX-2.2
native lib Version = RXTX-2.2pre2
I already looked up in the web but have not found any useful and the explanation.
And a possible solution I have found here I do not understand:
On Linux, the Uno and Mega 2560 show up as devices of the form /dev/ttyACM0. These are not supported by the standard version of the RXTX library that the Arduino software uses for serial communication. The Arduino software download for Linux includes a version of the RXTX library patched to also search for these /dev/ttyACM* devices. There's also an Ubuntu package (for 11.04) which includes support for these devices. If, however, you're using the RXTX package from your distribution, you may need to symlink from /dev/ttyACM0 to /dev/ttyUSB0 (for example) so that the serial port appears in the Arduino software.
I am looking forward to hear from you.
King regards,
Greenality
