nebgnahz 15:ac15ec676d87 2 * \brief CS294-84 demo \author Ben Zhang, Antonio Iannopollo
nebgnahz 14:efd42910791b 3 *
nebgnahz 14:efd42910791b 4 * This sampel code illustrates how to connect the mbed KL25Z platform to internet
nebgnahz 14:efd42910791b 5 * thorugh the CC3000 wifi breakout board (http://www.adafruit.com/product/1469).
nebgnahz 14:efd42910791b 6 * Connections between the KL25Z and the CC3000 are made according to the
nebgnahz 14:efd42910791b 7 * guide at https://learn.adafruit.com/adafruit-cc3000-wifi -- KL25Z and arduino
nebgnahz 14:efd42910791b 8 * UNO are pin to pin compatible --
nebgnahz 14:efd42910791b 9 *
nebgnahz 14:efd42910791b 10 * This application uses the following libraries:
nebgnahz 14:efd42910791b 11 * - cc3000_hostdriver_mbedsocket
nebgnahz 14:efd42910791b 12 * (http://developer.mbed.org/users/Kojto/code/cc3000_hostdriver_mbedsocket/)
nebgnahz 14:efd42910791b 13 * - HTTPClient (http://developer.mbed.org/users/donatien/code/HTTPClient/)
