Utilisation du GPS Garmin eTrex

author : echatellier <eric.chatellier@codelutin.com>

Detection par le systeme

  • Connecter le GPS au port Serie

  • Allumer le GPS

  • Attendre que le GPS affiche "Pret à naviguer"

À ce moment sous windows, il est possible que la souris se mettent à bouger toute seule. Il faut dans ce cas: * configurer le GPS sur l'interface Garmin * désinstaller le peripherique Souris détecté par Windows

Télécharger le logiciel "eTrex Legend C Software": * le lance * Auto detecter le GPS, cela doit afficher "Connected to serial port COM1".

Utilisation via Javagps

  • Ajouter le jar comm.jar

  • Le fichier java.com.properties

  • le fichier natif win32com.dll

Pas continuer.

Utilisation via GPSylon

Passer le GPS en mode "NMEA"

Rxtx

Rxtx est la lib de communication utilisée par GPSylon: http://www.cloudhopper.com/opensource/rxtx/

Apparement, sans le fichier "javax.comm.properties", cela ne fonctionne pas: les librairies natives ne sont pas trouvées.

RXTX est remplacé par nrjavaserial : http://code.google.com/p/nrjavaserial/ Il n'est plus nécessaire d'embarquer les librairies natives, elles sont incluses dans le jar de nrjavaserial.

Java web start

Pour java web start, il faut que les librairies natives sont packagées dans un jar et ajoutées au manifest jnlp: <nativelib href="lib/rxtx-win-xxx.jar" />

please see: How can I use Lock Files with rxtx? in INSTALL
