I created a class similar to the TcpServer class so the loop() method isn't
blocked until bytes have been read. It seems to work fine, but I want to
check with this group in case someone notices any potential issue. Note
that I start the thread in the loop() method instead of in the UARTServer
constructor.
class BalancerLooper extends BaseIOIOLooper implements LineListener {
UARTServer _uart;
boolean oneTime = true;
@Override
public void setup() throws ConnectionLostException {
_uart = new UARTServer(ioio_, this);
}
@Override
public void loop() throws ConnectionLostException {
try {
if (oneTime) {
new Thread(_uart).start();
oneTime = false;
}
} catch (InterruptedException e) {
ioio_.disconnect();
}
}
@Override
public void disconnected() {
_sequencer.close();
_uart.abort();
}
@Override
public void onLine(float throttle) {
Log.e("onLine", "MORE TODO HERE");
}
}
public class UARTServer implements Runnable {
interface LineListener {
public void onLine(float throttle);
}
private LineListener _listener;
private Uart _uart;
private IOIO _ioio;
private InputStream _uartInput;
int _inByte = 0; // in-coming serial byte
public UARTServer(IOIO ioio, LineListener listener) {
_listener = listener;
_ioio = ioio;
// new Thread(this).start();
}
@Override
public void run() {
try {
Thread.currentThread().setPriority(Thread.MAX_PRIORITY);
_uart = _ioio.openUart(5, 4, 9600, Uart.Parity.NONE, Uart.
StopBits.ONE);
_uartInput = _uart.getInputStream();
while (true) {
_inByte = _uartInput.read();
// decode message here…
}
} catch (IOException e) {
Log.e("IOException", e.getMessage());
} catch (ConnectionLostException e) {
Log.e("ConnectionLostException", e.getMessage());
}
}
void abort() {
try {
Log.e("NEW", "HERE");
if (_uartInput != null)
_uartInput.close();
if (_uart != null)
_uart.close();
} catch (IOException e) {
// Nothing to do at this point!
} finally {
_uartInput = null;
_uart = null;
}
}
}
