Java Serial Libraries

JAVA Serial libraries for UDOO NEO

This file describes how to compile and run the Java examples contained in this folder.

1 - Flash the Arduino™ Sketch using the Arduino IDE

1 - Install the OpenJDK Development Kit (JDK) (the headless version is good enough for this examples) and the javarxtx serial library.

sudo apt install openjdk-8-jdk-headless librxtx-java

2 - Open a terminal and navigate to this folder:

cd serial_libraries_examples/java/

3 - Check if the Arduino Leonardo is assigned to the default port /dev/ttyACM0, otherwise modify this string in the .java sources with correct tty and save:

UDOOserial.connect("/dev/ttyACM0");

4 - Compile the Java file:

for Java_serial_example.java:

javac -cp /usr/share/java/RXTXcomm.jar:. Java_serial_example.java

for Java_serial_example_bidirectional.java:

javac -cp /usr/share/java/RXTXcomm.jar:. Java_serial_example_bidirectional.java

5 - Run the Java program:

for Java_serial_example.java:

java -Djava.library.path=/usr/lib/jni -cp /usr/share/java/RXTXcomm.jar:. Java_serial_example

for Java_serial_example_bidirectional.java:

java -Djava.library.path=/usr/lib/jni -cp /usr/share/java/RXTXcomm.jar:. Java_serial_example_bidirectional
