5. Running the Demo

Follow the steps in the previous sections so that the iCE40 UltraPlus MDP and the Android phone are ready with the

necessary bitmap and application.

To run the demo:

26. Connect the Android phone application to the BLE device. Tap on the device that you want to connect with the

application as shown in Figure 5.1.

Figure 5.1. BLE Device Scan

27. Press the Start Demo button as shown in Figure 5.2.

28. Press the Airplane button. The FETCHING SENSOR DATA PLEASE WAIT message is displayed as shown in Figure

5.3.

Figure 5.3. Airplane Button

29. Move the MDP board for ten seconds until the LED stops blinking. The sensor data produced by the movement of

the MDP board is recorded.

Note: The application waits for the interruption. Once interruption occurs, the application reads the sensor data

from the buffer. Otherwise, the interface is reset and you need to press the Airplane button again.

30. If the data is collected successfully, the application uses these data to manipulate the 3D airplane image shown in

Figure 5.4. The movement of the airplane mimics the recorded movement of the MDP board in the previous step.

This playback also lasts for ten seconds.
