nebgnahz 14:efd42910791b 2 * \brief CS294-84 demo
nebgnahz 14:efd42910791b 3 * \author Ben Zhang, Antonio Iannopollo
nebgnahz 14:efd42910791b 4 *
nebgnahz 14:efd42910791b 5 * This sampel code illustrates how to connect the mbed KL25Z platform to internet
nebgnahz 14:efd42910791b 6 * thorugh the CC3000 wifi breakout board (http://www.adafruit.com/product/1469).
nebgnahz 14:efd42910791b 7 * Connections between the KL25Z and the CC3000 are made according to the
nebgnahz 14:efd42910791b 8 * guide at https://learn.adafruit.com/adafruit-cc3000-wifi -- KL25Z and arduino
nebgnahz 14:efd42910791b 9 * UNO are pin to pin compatible --
nebgnahz 14:efd42910791b 10 *
nebgnahz 14:efd42910791b 11 * This application uses the following libraries:
nebgnahz 14:efd42910791b 12 * - cc3000_hostdriver_mbedsocket
nebgnahz 14:efd42910791b 13 * (http://developer.mbed.org/users/Kojto/code/cc3000_hostdriver_mbedsocket/)
