gelöst: JAVA- ChibiExtension Probleme

Einstein · April 11, 2012 at 18:08

Hallo Leute,

ich hab folgendes Problem mit der ChibiExtension.

Über brickv stell ich Kanal 5 ein und mach einen Reset. Danach ist der Kanal der angezeigt wird 5-1 = 4. Das ist das erste Problem.

Wenn ich jetzt per java versuche die Frequenz auszulesen und den Kanal gibt es die Funktionen nicht in der Tinkerforge.jar (ich hab schon reingeschut in der Klasse BrickMaster fehlen die Funktionen einfach komplett.

hier der Fehler:

javac -cp Tinkerforge.jar:. ExampleStackStatus.java 
ExampleStackStatus.java:28: error: cannot find symbol
	short frequenz = master.getChibiFrequency();
	                       ^
  symbol:   method getChibiFrequency()
  location: variable master of type BrickMaster
ExampleStackStatus.java:30: error: cannot find symbol
	short kanal = master.getChibiChannel();
	                    ^
  symbol:   method getChibiChannel()
  location: variable master of type BrickMaster
2 errors

Ich hoffe es kann mir wer helfen.

Gruß

Welche Version der Bindings nutzt du denn? In 1.0.3 sind bei mir die ganzen Funktionen da in der BrickMaster.java: http://download.tinkerforge.com/bindings/java/

Ich nutze eigentlich die latest von heute.

hier der Auszug aus der BrickMaster.java

und hier meinen Quelltext den ich versucht habe

    private static final String host = new String("localhost");
    private static final int port = 4223;
    private static final String UID = new String("*****"); // Change to your UID
    
    // Note: To make the example code cleaner we do not handle exceptions. Exceptions you
    //       might normally want to catch are described in the commnents below
    public static void main(String args[]) throws Exception {
        // Create connection to brickd
        IPConnection ipcon = new IPConnection(host, port); // Can throw IOException

        BrickMaster master = new BrickMaster(UID); // Create device object

        // Add device to ip connection
        ipcon.addDevice(master); // Can throw IPConnection.TimeoutException
        // Don't use device before it is added to a connection
        
        // Get voltage and current from stack (in mV/mA)
        int voltage = master.getStackVoltage();
        int current = master.getStackCurrent();

if (master.isChibiPresent() == true)
{
	System.out.println("Chibi da");
	short frequenz = master.getChibiFrequency();
	System.out.println(frequenz);
	short kanal = master.getChibiChannel();
	System.out.println(kanal);
}
        System.out.println("Stack Voltage: " + voltage/1000.0 + " V");
        System.out.println("Stack Current: " + current/1000.0 + " A");
        
        System.out.println("Press ctrl+c to exit");
        ipcon.joinThread();
    }
}

Ich versteh es nicht ganz...vielleicht siehst du gleich das Problem

da fehlen ja wirklich die zwei Funktionen! Bei mir lokal waren sie drin und es hatte lokal die gleiche Version wie die letzte online.

Bin gerade durchgegangen, es fehlten überall die Funktionen außer bei den Python Bindings. D.h. ich muss überall alles geupdatet haben und dann aus irgendwelchen Gründen habe ich nur die Python Bindings hochgeladen. Oh man .

Probier es nochmal mit der neuesten Version: http://download.tinkerforge.com/bindings/java/

soo nun funktionierts wunderbar. ist nur noch die Frage bei 915MHz Kann ich zwar Kanal 5 auswählen, aber speichert bzw ich habs grad mit Java ausgelesen immer Kanal 4.

Er speichert immer Kanal der eingestellt ist -1.

Ich hoffe du kannst mit meiner Schilderung was anfangen.

Gruß

borg · April 11, 2012 at 22:01

Jop, Danke für den Tipp. Der 915Mhz Bereich fängt bei Channel 1 an (statt 0 wie bei den anderen Frequenzen). Da fehlt einfach ein +1 im Brick Viewer Code. Habs gefixt, werde in nächster Zeit sowieso eine neue brickv Version hochladen (mit RS485 support), da ists dann gefixt.

Gleich zwei Bugs auf einmal gefunden, nicht schlecht .

Immer gerne, klappte auch ganz gut mit dem fixen.

Thema kann geschlossen werden denke ich.
