bjo3rn 17:20238cbdcd9d 2 * \brief CS294-84 Chat Demo \author Ben Zhang, Antonio Iannopollo, Bjoern Hartmann
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).
bjo3rn 17:20238cbdcd9d 6 * Tap the slider past the midway point to generate an "ON" message;
bjo3rn 17:20238cbdcd9d 7 * release to generate an "OFF" message.
bjo3rn 17:20238cbdcd9d 8 *
nebgnahz 14:efd42910791b 9 * Connections between the KL25Z and the CC3000 are made according to the
nebgnahz 14:efd42910791b 10 * guide at https://learn.adafruit.com/adafruit-cc3000-wifi -- KL25Z and arduino
nebgnahz 14:efd42910791b 11 * UNO are pin to pin compatible --
nebgnahz 14:efd42910791b 12 *
nebgnahz 14:efd42910791b 13 * This application uses the following libraries:
nebgnahz 14:efd42910791b 14 * - cc3000_hostdriver_mbedsocket
nebgnahz 14:efd42910791b 15 * (http://developer.mbed.org/users/Kojto/code/cc3000_hostdriver_mbedsocket/)
nebgnahz 14:efd42910791b 16 * - HTTPClient (http://developer.mbed.org/users/donatien/code/HTTPClient/)
bjo3rn 17:20238cbdcd9d 17 * - tsi_sensor
