Demonstration

Connect the device USB port on the side of the LaunchPad to a standard computer USB port. Slide the power select switch to the left to choose power from the USB device port. The LaunchPad with the Sensor

Hub BoosterPack attached enumerates on the USB bus as a composite HID keyboard and mouse. A solid blue on the RGB LED indicates that the USB is properly enumerated. A quickly blinking red on the RGB

LED indicates that the motion system is operating correctly.

Hold the LaunchPad with the buttons away from the user and toward the computer; the USB device cable should exit the right and bottom corner of the board. Roll or tilt the LaunchPad to move the mouse cursor of the computer up, down and left, right. The buttons on the LaunchPad become the left- and right-mouse click buttons. The buttons on the Sensor Hub BoosterPack are not currently used by this example. A quick spin of the LaunchPad generates a PAGE_UP or PAGE_DOWN keyboard press and release, depending on direction of the spin. This action simulates page scrolling. A quick horizontal jerk to the left or right generates a CTRL+ or CTRL– keyboard event. This action creates a zoom effect in many applications, most often in web browsers. A quick vertical lift generates an ALT+TAB keyboard event. This action presents the computer user with an opportunity to select between currently open program windows. A quick twist to the left or right moves the window selector. A quick jerk in a downward direction selects the desired window and closes the window selection dialog.
