| 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) |
