91. GPIO PWM I2C I2S SPI Peripheral I/O UART
92. // Open a peripheral connection PeripheralManagerService service = new PeripheralManagerService(); Gpio button = service.openGpio(GPIO_PIN_NAME); // Configure the peripheral button.setDirection(Gpio.DIRECTION_IN); button.setEdgeTriggerType(Gpio.EDGE_FALLING); // Attach callback for input events button.registerGpioCallback(new GpioCallback() { @Override public boolean onGpioEdge(Gpio gpio) { Log.i(TAG, "GPIO changed"); // Return true to continue listening to events return true; } }); Simple Peripheral I/O
93. GPIO PWM I2C I2S SPI Audio Input Sensors Peripheral I/O User Drivers GPS UART
94. private GpioCallback callback = new GpioCallback() { @Override public boolean onGpioEdge(Gpio gpio) { int keyAction = gpio.getValue() ? KeyEvent.ACTION_DOWN : KeyEvent.ACTION_UP; inputDriver.emit(new KeyEvent[]{ new KeyEvent(keyAction, KeyEvent.KEYCODE_SPACE)}); return true; } }; Button User Driver InputDriver driver = new InputDriver.Builder(InputDevice.SOURCE_CLASS_BUTTON) .setName(DRIVER_NAME) .setVersion(DRIVER_VERSION) .setKeys(new int[]{KeyEvent.KEYCODE_SPACE}) .build(); UserDriverManager.getManager().registerInputDriver(driver);
95. GPIO PWM I2C I2S SPI Audio Input Sensors Peripheral Driver Library Peripheral I/O User Drivers GPS UART
96. dependencies { compile 'com.google.android.things.contrib:driver-button:...' } ButtonInputDriver inputDriver = new ButtonInputDriver( GPIO_PIN_NAME, Button.LogicState.PRESSED_WHEN_LOW , KeyEvent.KEYCODE_SPACE ); inputDriver.register(); Button Library Driver
