60 RPI with Ardulink

RPI with Ardulink

installation :

sudo apt-get install oracle-java7-jdk why not java8? 4um
sudo apt-get install librxtx-java
cd /usr/lib/jvm/jdk-7-oracle-armhf/jre/lib/arm
sudo ln -s /usr/lib/jni/librxtxSerial.so

cd /home/pi/

( check for new version pls )
wget http://arduinopclink.altervista.org/wp-content/uploads/2013/12/ardulink_v0.2.2.20131212.zip
unzip ardulink_v0.2.2.20131212.zip
cd ardulink
chmod +x ardulink.sh
chmod +x networkserver.sh

now, i work with RPI + arduino and processing and python
but also long time ago with firmata,
so i understand that here something is missing!
SHOULD THERE BE A PROGRAM IN THE ARDUINO?
try a
ls /home/pi/ardulink/sketches/ArdulinkProtocol/
even i not see it mentioned in the installation manual
i think i should load that arduino sketch.
BUT first:
install arduino IDE on the RPI

sudo apt-get install arduino
start arduino IDE from VNC
| File | Preferences | Browse | /home/pi/ardulink/sketches [OK]
| File | Sketchbook | ArdulinkProtocol |
| Tools | Board | yourboard type
| Tools | Serialport | devTTYACM0
-> UPLOAD
( done uploading )
close the arduino IDE window

---

as above we see the board on ACM0

ln -s /dev/ttyACM[x] /dev/ttyS8[x]

sudo ln -s /dev/ttyACM0 /dev/ttyS80

from a VNC Desktop open terminal
cd /home/pi/ardulink/
bash ardulink.sh OR
./ardulink.sh
open that console.

from putty show error.
pi@arduRPI ~/ardulink $ bash ardulink.sh
java.awt.HeadlessException:
No X11 DISPLAY variable was set, but this program performed an operation which r equires it.
there is a youtube video how to do this, but i can see nothing
sorry

in Connection type that
/dev/ttyS80 OR search ( by the magnifier button and select port..)
and press button [Connect]
and get the info down left: connected.

lets also see here that the RPI cpu is ( permanent ) on 100%

TEST OPERATION:
make a jumper between 2 digital ports,
and in TAB Sensor Digital Panel switch sensor ON and see a LOW,
in TAB Switch Panel SET OUTPUT to ON
and check in TAB Sensor Digital Panel and see a HIGH.
nice, but

INSTEAD OF JAVA I WOULD LIKE TO SEE THIS IN PYTHON.
