6.3 Audio with controls Demo

This demo shows how to create a simple audio device with HID controls for next, previous, play/pause, and volume control.

This demo requires no app associated with it. A user can use any audio source on the target tablet/phone to generate the

audio.

6.3.1 Running the demo

1. Attach the Accessory Development Starter Board to the Android device using the connector provided by the Android

device’s manufacturer. Please make sure that the accessory is attached to the Android device before launching the

application.

2. Once attached, the core audio should now be pumped to the accessory. Please note that the audio data is received by the

application code, but is not used as there is not currently a board supported that has the capability to generate audio.

3. The pushbuttons on the board control the next, previous, and play/pause feature. Please press and hold each button for a

second to enable the feature. The potentiometer on the board will control the audio.
