Dear list,
I am trying to use librxtx to access the GPS device in my FreeRunner through
the /dev/ttySAC1 serial port. I have done this:
opkg install librxtx-java
opkg install librxtx-jni
In the classpath of my little java app I have added RXTXcomm.jar and tried to
execute this code without success. No ports are discovered (with the GPS on and
off), and if I try to access a port called /dev/ttySAC1, it says it does not
exist. What am I doing wrong?
=================================
static void listPorts()
{
java.util.Enumeration portEnum =
CommPortIdentifier.getPortIdentifiers();
while ( portEnum.hasMoreElements() )
{
CommPortIdentifier portIdentifier = (CommPortIdentifier)
portEnum.nextElement();
System.out.println(portIdentifier.getName() + " - " +
getPortTypeName(portIdentifier.getPortType()) );
}
}
static String getPortTypeName ( int portType )
{
switch ( portType )
{
case CommPortIdentifier.PORT_I2C:
return "I2C";
case CommPortIdentifier.PORT_PARALLEL:
return "Parallel";
case CommPortIdentifier.PORT_RAW:
return "Raw";
case CommPortIdentifier.PORT_RS485:
return "RS485";
case CommPortIdentifier.PORT_SERIAL:
return "Serial";
default:
return "unknown type";
}
}
=================================
Regards,
Juan Lucas
