The Mobile Control II SDK provides access to the throttle, keys and LEDs.
Current Version: 1.1.1
- Open the
build.gradlefile of your application. - Add the SDK to the
dependenciessection:
dependencies {
...
compile 'eu.esu.mobilecontrol2:mobilecontrol2-sdk:1.1.1'
}You can check if your app is running on the Mobile Control II by calling
boolean runsOnMc2 = MobileControl2.isMobileControl2();The ThrottleFragment, StopButtonFragment as well as the MobileControl2.setLedState() methods are designed to do nothing when not running on the Mobile Control II, so you will not need to check this very often.
To access the throttle just add the ThrottleFragment to your activity:
@Override
protected void onCreate(Bundle savedInstanceState) {
...
mThrottleFragment = ThrottleFragment.newInstance(1);
mThrottleFragment.setOnThrottleListener(mOnThrottleListener);
getSupportFragmentManager().beginTransaction()
.add(mThrottleFragment, "mc2:throttle")
.commit();
...
}Make sure you ignore the ThrottleFragment.KEYCODE_THROTTLE_WAKEUP KeyCode to prevent user input:
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == ThrottleFragment.KEYCODE_THROTTLE_WAKEUP) {
return true;
}
...
}To change the throttle position call moveThrottle() with a value between 0 (start) and 255 (end):
// Move the throttle to the middle
int position = 127;
mThrottleFragment.moveThrottle(position);Use the ThrottleFragment.OnThrottleListener to receive callbacks:
private ThrottleFragment.OnThrottleListener mOnThrottleListener = new OnThrottleListener() {
@Override
public void onButtonDown() {
// The throttle button is in pressed state.
}
@Override
public void onButtonUp() {
// The throttle button is in released state.
}
@Override
public void onPositionChanged(int position) {
// The new throttle position from 0 to 255.
}
}; The ThrottleScale class provides a convenient way to convert the throttle position to speed steps and vice versa. The example code shows how to use ThrotleScale for values from 0 - 28.
ThrottleScale mThrottleScale = new ThrottleScale(10, 29);
// Convert throttle position to speed step
int step = mThrottleScale.positionToStep(position);
// ... or step to position
int position = mThrottleScale.stepToPosition(step);The constructor takes two parameters:
The first parameter defines the zero Range: If the throttle position is between 0 - 10 positionToStep() will return 0. The second parameter defines the actual number of steps including zero. 0 - 28 <=> 29 steps.
You will also need to add the StopButtonFragment to your activity if you want to listen to Stop button events.
@override
protected void onCreate(Bundle savedInstanceState) {
...
StopButtonFragment stopButtonFragment = StopButtonFragment.newInstance();
stopButtonFragment.setOnStopButtonListener(mStopButtonListener);
getSupportFragmentManager().beginTransaction()
.add(stopButtonFragment, "mc2:stopButton")
.commit();
}Use the StopButtonFragment.OnStopButtonListener to receive events.
private StopButtonFragment.OnStopButtonListener mOnStopButtonListener = new StopButtonFragment.OnStopButtonListener() {
@Override
public void onStopButtonDown() {
// The stop button is pressed.
}
@Override
public void onStopButtonUp() {
// The stop button is released.
}
};Turn a LED on:
MobileControl2.setLedState(MobileControl2.LED_RED, true);Turn a LED off:
MobileControl2.setLedState(MobileControl2.LED_GREEN, false);LED flashing is also supported:
MobileControl2.setLedState(MobileControl2.LED_RED, 250, 250);Available LEDs are MobileControl2.LED_GREEN and MobileControl2.LED_RED.
The side buttons of the Mobile Control II are using existing Android key codes. The MobileControl2 class provides constants:
MobileControl2.KEYCODE_TOP_RIGHT: Top right.
MobileControl2.KEYCODE_BOTTOM_RIGHT: Bottom right.
MobileControl2.KEYCODE_TOP_LEFT: Top left.
MobileControl2.KEYCODE_BOTTOM_LEFT: Bottom left.
Make sure you check you are running on a Mobile Control II before using the key codes:
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (MobileControl2.isMobileControl2()) {
// Handle Mobile Control II keys
}
else {
// Handle default keys.
}
} Checkout the Mobile Control II SDK sample app.
