2.3.3
MediaPad
This section describes instructions to run the MediaPad application on the LaunchPad Capacitive Touch
BoosterPack and the PC. It assumes that the hardware is connected to the PC via USB cable (see step 1
of
Section 2.3.1
) and that the software has been installed (see
Section 2.2
).
1. Start the MediaPad.exe application located at [INSTALL_PATH]\Software\MediaPad\
2. At startup, the application searches for a LaunchPad or an eZ430 emulator compatible USB serial
COM port.
If no compatible COM port is found, the application displays an error message and then exits.
If a LaunchPad COM port is found, the application displays a greeting message. When the user closes
the message, the application minimizes itself to the taskbar.
3. When the LaunchPad Capacitive Touch BoosterPack is in sleep mode, no data is transferred and no
activity occurs in the program. Use hand/finger wave motion to trigger the proximity sensor and wake
up the device.
4. The following touches or gestures can be used for media control in a Windows system (see
Figure 5
).
(a) Center button press: Start media player (Windows Media Player by default)
(b) Bottom arrow button press: Play/Pause
(c) Left arrow button press: Previous Track
(d) Right arrow button press: Next Track
(e) Scroll wheel clockwise: Volume Up
(f) Scroll wheel counter-clockwise: Volume Down

Using the wheel, a hidden mode can be unlocked. Input the correct sequence (similar to a rotational combination lock) to reveal a secret.
