| iva2k | 0:5e068c08724a | 3 | // Example of HTTPServer with additional features: |
| iva2k | 0:5e068c08724a | 4 | // * Link status indication (LED4) |
| iva2k | 0:5e068c08724a | 5 | // * Local file system (create index.htm page on MBED!) |
| iva2k | 0:5e068c08724a | 6 | // * RPC-able class (myrpc, allows remote function call that blinks LED1 N times) |

| iva2k | 0:5e068c08724a | 8 | // Instructions: |
| iva2k | 0:5e068c08724a | 9 | // 1 Plug MBED into BoB2 (or other ETH connector breakout) |
| iva2k | 0:5e068c08724a | 10 | // 2 Plug ETH connector into your network (needs DHCP to get IP address) |
| iva2k | 0:5e068c08724a | 11 | // 3 Power up MBED using USB cable |
| iva2k | 0:5e068c08724a | 12 | // 4 Install MBED serial driver (http://mbed.org/handbook/SerialPC) |
| iva2k | 0:5e068c08724a | 13 | // 5 Copy compiled .bin to your MBED (make sure target device selected in the compiler is correct) |
| iva2k | 0:5e068c08724a | 14 | // 6 Open terminal on the mbed serial port |
| iva2k | 0:5e068c08724a | 15 | // 7 Push MBED reset button |
| iva2k | 0:5e068c08724a | 16 | // 8 Terminal will display info message with mac address, followed by IP address (if connection succeeds) |
| iva2k | 0:5e068c08724a | 17 | // 9 Open browser and enter the following URL, inserting your MBED's IP address: |
| iva2k | 0:5e068c08724a | 18 | // http://10.0.0.321/rpc/myrpc1/blink,10 (instead of 10.0.0.321 use MBED IP address from terminal) |
| iva2k | 0:5e068c08724a | 19 | // 10 MBED will blink the LED 10 times |
| iva2k | 0:5e068c08724a | 20 | // |
| iva2k | 0:5e068c08724a | 21 | // Notes: there are still some bugs in HTTPServer code. |
| iva2k | 0:5e068c08724a | 22 | // To help fight some of them, copy a valid favicon.ico (a 16x16 icon) file to MBED. |
