Example Program
To make sure this API is workable with the device server on an Android platform, see the example program
below:
Thread thread = new Thread()
{
@Override
public void run() {
/* Enumerate and initialize NPorts on system */
List<MxNPort> NPortList = MxNPortService.getNPortInfoList();
if(NPortList!=null){
MxNPort.IoctlMode mode = new MxNPort.IoctlMode();
mode.baudRate = 38400;
mode.dataBits = MxNPort.DATA_BITS_8;
mode.parity = MxNPort.PARITY_NONE;
mode.stopBits = MxNPort.STOP_BITS_1;
MxNPort mxNPort = NPortList.get(0);
/* Get first NPort device */
try {
byte[] buf = {'H','e','l','l','o',' ','W','o','r','l','d'};
mxNPort.open();
/*open port*/
mxNPort.setIoctlMode(mode);
/*serial parameters setting*/
mxNPort.write(buf, buf.length);
/*write data*/
mxNPort.close(); /*close port*/
} catch (MxException e){
/*Error handling*/
}
}
}
};
thread.start();
