Hello community,

I've had trouble to get Arduino IDE up and running on my system. However, I think I solved it and I wanna share my solution with you.

Go to https://launchpad.net/ubuntu/natty/+source/arduino
At the right side there are links to binary files listed. That is "arduino-core" and "arduino". Follow the links or if you want to get the 64bit version, go directly to:

• https://launchpad.net/ubuntu/natty/amd64/arduino-core/0022+dfsg-1
• https://launchpad.net/ubuntu/natty/amd64/arduino/0022+dfsg-1

Install "arduino-core" then "arduino". This is because "arduino" requires "arduino-core" to be installed before.

That installation was quick, wasn't it? Now you can start up the IDE from Ubuntu's menu Applications > Programming > Arduino IDE.

After that installation I found out that Tools > Serial Port was grayed out.


I found out that /dev/ttyACM0 is the device (Arduino Uno) I wanna talk to. I was able to execute ...

Code:

echo "ciao" > /dev/ttyACM0

... and see the RX led blinking. Thus at least there was a reaction, basically a connection was possible.

To cut a long story short ... I tried several ways to get /dev/ttyACM0 visible in that menu. In the end all I needed to change was adding a symbolic link. I created that with ...

Code:

sudo ln -s /dev/ttyACM0 /dev/ttyS10

I choosed ttyS10 because ttyS0 was already occupied.

After restarting the Arduino IDE, the menu item Tools > Serial Port became enabled and I had /dev/ttyS10 as an entry in there. Then I uploaded "Examples > Basics > Blink" and Arduino started blinking.

Please respond if this short description helped you too.

Regards

Noisybit, are you using the amd64 flavor of Ubuntu?

[Reply #2 on:]

Hello noisybit,  can you tell me what kernel version you are running?  Thanks

[Reply #3 on:]

Noisybit,

Your instructions worked!  The only issue I have is I have to run

Code:

sudo ln -s /dev/ttyACM0 /dev/ttyS10

every time I start the Arduino software.  I'm new to Linux and not sure what the work around would be for this.

FYI: I'm running KUBUNTU amd64 10. something.

I had the Arduino running earlier with the help of a couple of posts in the old forum.  http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1293243021/0  I had run it from the directory that I installed it using "dolphin".

There's an updated version of the RXTX package for Debian / Ubuntu (rxtx (2.2pre2-3)) that adds support for the /dev/ttyACM* devices. 

https://launchpad.net/ubuntu/natty/+source/rxtx

I'm not sure if it's been backported to any of the shipping distributions yet or what you'd need to do to install it.

Hi all,

Machine hardware name:

Code:

noisybit@noisybit-desktop:~$ uname -m
x86_64

Kernel release:

Code:

noisybit@noisybit-desktop:~$ uname -r
2.6.32-28-generic

Kernel version:

Code:

noisybit@noisybit-desktop:~$ uname -v
#55-Ubuntu SMP Mon Jan 10 23:42:43 UTC 2011

purza, you're right. After rebooting the link was gone. Creating the link / alias automatically right after plugging in Arduino Uno may be solved with some udev rules - but frankly I've no idea how it works. But wait until you read next paragraph ...

Now I downloaded and installed the package that mellis pointed to. And ... it worked! I now can see the /dev/ttyACM0 as menu item. So there is no need anymore to have the workaround with the symbolic link.

[Reply #6 on:]

I had the same problems when I started with Ardunio this weekend (using openSuse 11.3/64).
Creating a symbolic link using option -S will forget it on reboot. But making a permanent in in this system controlled directory is not advisable.

I found here http://andypiper.co.uk/2010/12/21/prototyping-arduino-and-ubuntu/ the instruction for a proper solution: define a rule in the USB configuration. I copied the relevant text below.
Success.

Creating static symbolic links in /dev is a bit hokey these days, of course, so I moved across to udev and created a new rule for the UNO in a file called /etc/udev/rules.d/80-arduino-uno.rule

KERNEL=="ttyACM*", ATTRS{product}=="Arduino*", SYMLINK+="ttyUSB%n"

dead simple: if a new device pops up in the kernel named ttyACMsomething, and it has a USB product ID string starting Arduino (which mine does, I checked using the command usb-devices), add another symlink to it at ttyUSBsomething, thanks. Result:

Dec 21 19:18:50 agrippa kernel: [21501.209012] usb 1-1.1: new full

Noisybit and Mellis,

Excuse my ignorance, but how do I install the file(s) https://launchpad.net/ubuntu/natty/+source/rxtx

It would seem I just need to download the latest version "rxtx_2.2pre2-3.debian.tar.gz" and then install it.   But from where... and how...  I've done this before, but having trouble remembering exact procedure. 

Thanks.

Working on this stuff as a hobby in my spare time... when I'm not doing my real jobs, servicing electron microscopes and keeping up the household.

With 64-bit Ubuntu 10.10, it works, but that may be because of the library with the Arduino version 21 and 22:

Code:

WARNING:  RXTX Version mismatch
Jar version = RXTX-2.1-7
native lib Version = RXTX-2.2pre2

I did have problems with Arduino 21 and Unos on 32-bit Ubuntu, but my solution was just to use Duemilanoves

For Arduino 22 on 64-bit Ubuntu, it is currently necessary to copy the arduino-0021/lib/librxtxSerial.so from the 64-bit version of Arduino 21 to arduino-0022/lib/, overwriting the (32-bit) .so currently there.

[Reply #9 on:]

If I understand you correctly. I need to copy this jar file "RXTXcomm.jar" from the 0021/lib folder to the arduino-0022/lib/ folder?

Excuse my ignorance, but how do I install the file(s) https://launchpad.net/ubuntu/natty/+source/rxtx

First sorry for my late response.

Installation ...

• Go here https://launchpad.net/ubuntu/natty/amd64/librxtx-java/2.2pre2-3.
• Below "Downloadable files", click on the link to librxtx-java_2.2pre2-3_amd64.deb.
• Then, Firefox asks me whether to open the link with GDebi Package Installer (see attached image).
• Click on "OK".

The installation alone worked for me. No additional links in /dev folder, nor copying files around by myself.

Awesome!!! Thank you!  It worked!
