SpotPilot - Reading NMEA sentences from the GPS
Posted by: Paul René Jørgensen in Airplane, Java, tags: autopilot, gps, Java, nmea, spot, sun, sun spotTonight I upgraded one of my Sun Spots to the new beta release of the blue firmware. One of the changes were an important bugfix in the UART code of the daughter board handling the UART buffers.
Anyway, after upgrading I wrote some test code to display the NMEA data from the GPS and guess what.. It worked!
EDemoBoard edb = EDemoBoard.getInstance();
edb.initUART(edb.SERIAL_SPEED_4800, edb.SERIAL_DATABITS_8, edb.SERIAL_PARITY_NONE, edb.SERIAL_STOPBITS_1);
while(true) {
try {
System.out.print((char) edb.readUART(1000));
} catch (IOException e) {
e.printStackTrace();
}
}
And the output (No fix. I was in my livingroom)..
