Hi all,
I tried modifying the HelloIOIO program to test Input and output on custom
pins.
The program starts and shows the Toast for a successful connection.
But then it disconnects.
Kindly advice what could wrong.
public class MainActivity extends IOIOActivity {
private ToggleButton button_;
private ToggleButton button_input;
/**
* Called when the activity is first created. Here we normally initialize
* our GUI.
*/
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
button_ = (ToggleButton) findViewById(R.id.button);
button_input = (ToggleButton) findViewById(R.id.button_input);
}
/**
* This is the thread on which all the IOIO activity happens. It will be run
* every time the application is resumed and aborted when it is paused. The
* method setup() will be called right after a connection with the IOIO has
* been established (which might happen several times!). Then, loop() will
* be called repetitively until the IOIO gets disconnected.
*/
class Looper extends BaseIOIOLooper {
/** The on-board LED. */
private DigitalOutput led_;
private DigitalOutput mOutput;
private DigitalInput mInput_;
/**
* Called every time a connection with IOIO has been established.
* Typically used to open pins.
*
* @throws ConnectionLostException
* When IOIO connection is lost.
*
* @see ioio.lib.util.IOIOLooper#setup()
*/
@Override
protected void setup() throws ConnectionLostException {
showVersions(ioio_, "IOIO connected!");
led_ = ioio_.openDigitalOutput(0, true);
/** Output is being tested on PIN 41 and input on
pin 42 . With PULL_DOWN option on pin42, my assumption is that the pin 42
should be
setup at 0V **/
mOutput = ioio_.openDigitalOutput(41, true);
mInput_ = ioio_.openDigitalInput(42, DigitalInput.Spec.Mode.PULL_DOWN);
enableUi(true);
}
/**
* Called repetitively while the IOIO is connected.
*
* @throws ConnectionLostException
* When IOIO connection is lost.
* @throws InterruptedException
* When the IOIO thread has been interrupted.
*
* @see ioio.lib.util.IOIOLooper#loop()
*/
@Override
public void loop() throws ConnectionLostException, InterruptedException {
toast("working 1");
led_.write(!button_.isChecked());
toast("working 2");
Thread.sleep(100);
toast("working 3");
if(button_input!= null) {
button_input.setChecked(mInput_.read());
}else{
toast("Bhai null pointer");
}
}

toast("IOIO disconnected");
}
/**
* Called when the IOIO is connected, but has an incompatible firmware
version.

showVersions(ioio_, "Incompatible firmware version!");
}
}
/**

@Override

return new Looper();
