/** * \brief CS294-84 demo * \author Ben Zhang, Antonio Iannopollo * * This sampel code illustrates how to connect the mbed KL25Z platform to internet * thorugh the CC3000 wifi breakout board (http://www.adafruit.com/product/1469). * Connections between the KL25Z and the CC3000 are made according to the * guide at https://learn.adafruit.com/adafruit-cc3000-wifi -- KL25Z and arduino * UNO are pin to pin compatible -- * * This application uses the following libraries: * - cc3000_hostdriver_mbedsocket * (http://developer.mbed.org/users/Kojto/code/cc3000_hostdriver_mbedsocket/) * - HTTPClient (http://developer.mbed.org/users/donatien/code/HTTPClient/) */ #include "mbed.h" #include "cc3000.h" #include "HTTPClient.h" // KL25Z wifi connection // we need to define connection pins for: // - IRQ => (pin D3) // - Enable => (pin D5) // - SPI CS => (pin D10) // - SPI MOSI => (pin D11) // - SPI MISO => (pin D12) // - SPI CLK => (pin D13) // plus wifi network SSID, password, security level and smart-configuration flag. mbed_cc3000::cc3000 wifi(D3, D5, D10, SPI(D11, D12, D13), "SSID", "PASSWORD", WPA2, false); // create an http instance HTTPClient http; // str is used to hold the response data char str[512]; // setup the serial connection, and LEDs Serial pc(USBTX, USBRX); DigitalOut led_red(LED_RED); DigitalOut led_green(LED_GREEN); int main() { // by default, it's red led_red = 0; led_green = 1; // print message to indicate the program has started pc.printf("CC3000 Sample Program\r\n"); wifi.init(); while(1) { // continuosly check connection status if(wifi.is_connected() == false) { // try to connect if (wifi.connect() == -1) { printf("Failed to connect.
