how to resolve jdk.dio-CloseDeviceException [message #1714353]

this is how my code looks like:
package org.eclipse.kura.examples.gpioCheck;

import java.io.IOException;

import jdk.dio.ClosedDeviceException;
import jdk.dio.Device;
import jdk.dio.DeviceManager;
import jdk.dio.UnavailableDeviceException;
import jdk.dio.gpio.GPIOPin;

public class GpioTry {

Device<?> pin1,pin2,pin3,pin4,pin5,pin6,pin7,pin8,pin9;
GPIOPin led1,led2,led3,led4,led5,led6,led7,led8,led9;
protected void activate(){
try {
pin1 = DeviceManager.open(17);
pin2 = DeviceManager.open(14);
pin3 = DeviceManager.open(15);
pin4 = DeviceManager.open(16);
pin5 = DeviceManager.open(7);
pin6 = DeviceManager.open(0);
pin7 = DeviceManager.open(1);
pin8 = DeviceManager.open(4);
pin9 = DeviceManager.open(21);
} catch (Exception e){
e.printStackTrace();
}
led1 = (GPIOPin)pin1;
led2 = (GPIOPin)pin2;
led3 = (GPIOPin)pin3;
led4 = (GPIOPin)pin4;
led5 = (GPIOPin)pin5;
led6 = (GPIOPin)pin6;
led7 = (GPIOPin)pin7;
led8 = (GPIOPin)pin8;
led9 = (GPIOPin)pin9;
blink();
}

protected void ledOn(){
try {
led1.setValue(true);
led2.setValue(true);
led3.setValue(true);
led4.setValue(true);
led5.setValue(true);
led6.setValue(true);
led7.setValue(true);
led8.setValue(true);
led9.setValue(true);
} catch (UnavailableDeviceException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ClosedDeviceException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

protected void ledOff(){

try {
led1.setValue(false);
led2.setValue(false);
led3.setValue(false);
led4.setValue(false);
led5.setValue(false);
led6.setValue(false);
led7.setValue(false);
led8.setValue(false);
led9.setValue(false);
} catch (UnavailableDeviceException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ClosedDeviceException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

protected void blink(){

for(int i = 0; i < 10; i++){
try {
ledOn();
Thread.sleep(1000);
ledOff();
Thread.sleep(1000);
} catch (Exception e){
e.printStackTrace();
}
}
}

protected void ledClose(){
try {
led1.close();
led2.close();
led3.close();
led4.close();
led5.close();
led6.close();
led7.close();
led8.close();
led9.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

protected void deactivate(){
ledClose();
}

}

and then the error:

Hello,

Did you setup these pins in the jdk.dio.properties file? If so, can you please post the contents of that file? More documentation can be found here: http://eclipse.github.io/kura/doc/kura-dio-apis.html .

Thanks,
--Dave

The best first step would be to manually get one of your pins working before modifying the jdk.dio.properties file. The documentation describes how to do this, but the relevant code should look something like:

GPIOPinConfig pinConfig = new GPIOPinConfig(
    DeviceConfig.DEFAULT,                       //GPIO Controller number or name
    17,                                                 //GPIO Pin number
    GPIOPinConfig.DIR_INPUT_ONLY,               //Pin direction
    GPIOPinConfig.MODE_INPUT_PULL_DOWN,     //Pin resistor
    GPIOPinConfig.TRIGGER_BOTH_EDGES,       //Triggers
    false                                           //initial value (for outputs)
);

Thanks,
--Dave

Hello Akash,
How did you manage to add the jdk.dio library to your work space ?
I couldn't find it in my dependencies

Thanks
