Step 5: If there is no error (warnings may come), then your setup is right and you can now read the Arduino data in your serial port of Raspberry Pi, with the step 4 Java compiled code. Javac -source 1.6 -target 1.6 -cp /usr/lib/jvm/jdk-8-oracle-arm-vfp-hflt/jre/lib/RXTXcomm.jar SerialTestGET.java public class SerialTestGET implements SerialPortEventListener.sudo apt-get install oracle-java8-installer Step 3: Now you can copy below Java code. If you don’t, then your Java won’t be updated to jdk-8 and you have to update the JDK and JRE. Now, we are assuming here that you have your jdk-8-oracle-arm-vfp-hflt inside your /usr/lib/jvm. Sudo cp librxtxSerial.so /usr/lib/jvm/jdk-8-oracle-arm-vfp-hflt/lib/arm Sudo cp RXTXcomm.jar /usr/lib/jvm/jdk-8-oracle-arm-vfp-hflt/jre/lib Sudo cp libjawt.so /usr/lib/jvm/jdk-8-oracle-arm-vfp-hflt/lib/arm So Download the below files :Īnd go to the download folder of the files and type below commands: Step 2: The communication is in serial mode, between Arduino and Raspberry Pi, so we need a way to make our Java program to understand it. When you update your Raspbian, it will also update the Java library, if required. Usually Raspbian comes with Java installed but you can still check it via the following command: Step 1: Install java in the Raspberry Pi. This part is the most challenging part for someone who is new to Raspberry Pi, so we have decided to create the entire setup in the utmost simplistic way in 5 sub-steps: Now we are going to perform: Step 3 – Using Java in Raspberry Pi in order to read serial data of Arduino
