15.3. Control of the module part
Each module can be controlled in a similar manner, you can find below a simple sample program
displaying the main parameters of the module and enabling you to activate the localization beacon.
import com.yoctopuce.YoctoAPI.* ;
import java.util.logging.Level ;
import java.util.logging.Logger ;
public class Demo {
public static void main ( String [] args )
{
try {
// setup the API to use local VirtualHub
YAPI. RegisterHub ( "127.0.0.1" ) ;
} catch ( YAPI_Exception ex ) {
System . out . println ( "Cannot contact VirtualHub on 127.0.0.1 (" +
ex. getLocalizedMessage () + ")" ) ;
System . out . println ( "Ensure that the VirtualHub application is running" ) ;
System . exit ( 1 ) ;
}
System . out . println ( "usage: demo [serial or logical name] [ON/OFF]" ) ;
YModule module;
if ( args. length == 0 ) {
module = YModule. FirstModule () ;
if ( module == null ) {
System . out . println ( "No module connected (check USB cable)" ) ;
System . exit ( 1 ) ;
}
} else {
module = YModule. FindModule ( args [ 0 ]) ; // use serial or logical name
}
try {
if ( args. length > 1 ) {
if ( args [ 1 ] . equalsIgnoreCase ( "ON" )) {
module. setBeacon ( YModule. BEACON_ON ) ;
} else {
module. setBeacon ( YModule. BEACON_OFF ) ;
}
}
