This is just a simple test program **to check the hardware**: mbeduino and 4x4x4 LED_cube shield. \\ A class library is available for easy operation. Please find it at...\\ http://mbed.org/users/okano/libraries/LED_Cube444/\\ There are two demo programs for this library available. Please find those at...\\ (1) Very simplified demo sample code : \\ http://mbed.org/users/okano/programs/LED_Cube444_mbeduino-very_simple_demo/\\ (2) More complex (fancy) demo : \\ http://mbed.org/users/okano/programs/LED_Cube444_mbeduino_demo/\\ About the hardware: \\ http://mbed.org/users/okini3939/notebook/mbeduino/ \\ http://www.galileo-7.com/?pid=20015630 \\
