3. In the Flash File Controls pane, click the Erase button to erase any possible preexist-
ing code in memory.
4. Click the Program and Verify button. The programming and verifying process will
take a few seconds to complete. When this process is complete, click the Close but-
ton.
5. Switch off the power to the Platform, and disconnect the USB Smart Cable.
6. Reapply power to the Platform, and press the Platform’s RESET button to ensure that
the LightMeUp project will run from the beginning of the program.
PC Independent/Mobile Mode
Operation in PC Independent/Mobile Mode requires the user to write an application. For
the Platform to perform independently from a PC, it must first be flashed (i.e., prepro-
grammed) with a self-contained program that utilizes the keypad as its main source of
input and control. This control can also be performed wirelessly by another Bluetooth-
enabled device; e.g., an iPhone application that will issue commands to or request infor-
mation from the Educational Platform.
PC Independent/Mobile Mode is dependent on a specific application designed for mobile
use. For example, field measurements of differing environmental conditions could be
gathered by Bluetooth-enabled sensors on a battery-powered Platform populated with a
ZPAN (Bluetooth) shield.
Hardware
The shield interface provides two 30-pin indexed sockets that allow access to 48 general-
purpose I/O lines. Each shield is stackable, and is identified by a symbol such as a triangle,
square, or circle. Although not necessary for basic Platform operation, shields displaying
the same symbol can be stacked onto each other to multiply the functionality of the Plat-
form without sacrificing project real estate.
