frankvnk 5:bd9705c7cf51 3 * Dynamic HTML string handlers:
frankvnk 5:bd9705c7cf51 4 * Nine dynamic HTML fields are updated on browser refresh or button press:
frankvnk 5:bd9705c7cf51 5 * Acceleration
frankvnk 5:bd9705c7cf51 6 * Magnetometer
frankvnk 5:bd9705c7cf51 7 * eCompass
frankvnk 5:bd9705c7cf51 8 * Altitude
frankvnk 5:bd9705c7cf51 9 * Battery Voltage
frankvnk 5:bd9705c7cf51 10 * Ambient Light
frankvnk 5:bd9705c7cf51 11 * Temperature
frankvnk 5:bd9705c7cf51 12 * Slider Position
frankvnk 5:bd9705c7cf51 13 * Page Views
frankvnk 5:bd9705c7cf51 14 *
frankvnk 5:bd9705c7cf51 15 * CGI HTML forms:
frankvnk 5:bd9705c7cf51 16 * Three CGI form inputs are used to submit data from browser to the Server:
frankvnk 5:bd9705c7cf51 17 * On screen buttons: -Red-, Green, Blue (for control of RGB LED output color)
frankvnk 5:bd9705c7cf51 18 *
frankvnk 5:bd9705c7cf51 19 * myindex[] contains the HTML string that defines the webpage that is served
frankvnk 5:bd9705c7cf51 20 * Use an online HTML validator to verify HTML code before running it on the MCU
frankvnk 5:bd9705c7cf51 21 * eg.
frankvnk 5:bd9705c7cf51 22 * www.w3schools.com/tags/tryit.asp?filename=tryhtml_div_test
frankvnk 5:bd9705c7cf51 23 * www.onlinewebcheck.com/check.php?adv=1
frankvnk 5:bd9705c7cf51 24 * Note: Before checking the HTML in one of these validators,
frankvnk 5:bd9705c7cf51 25 * strip-out all “\” backslash characters (using search & replace)
frankvnk 5:bd9705c7cf51 26 *
frankvnk 5:bd9705c7cf51 27 * Webserver code is based on TI's CC3000 Simple HTTP Webserver:
frankvnk 5:bd9705c7cf51 28 * http://processors.wiki.ti.com/index.php/CC3000_Wi-Fi_for_MCU
frankvnk 5:bd9705c7cf51 29 *
frankvnk 5:bd9705c7cf51 30 * More detail on implementation of this Webserver App is available here:
frankvnk 5:bd9705c7cf51 31 * http://processors.wiki.ti.com/index.php/CC3000_HTTP_Server_Demo_Session
frankvnk 5:bd9705c7cf51 32 *
frankvnk 5:bd9705c7cf51 33 * A more advanced Webserver and Client App is also available from TI for the CC3000:
frankvnk 5:bd9705c7cf51 34 * http://processors.wiki.ti.com/index.php/CC3000_Web_Server_Client_Application
frankvnk 5:bd9705c7cf51 35 * (at this time not yet ported to Kinetis-L as the host processor)
frankvnk 5:bd9705c7cf51 36 *
