| tuxic | 0:5c9e0971532d | 2 | * example program for TFTPServer class |
| tuxic | 0:5c9e0971532d | 3 | * |
| tuxic | 0:5c9e0971532d | 4 | * How to use: |
| tuxic | 0:5c9e0971532d | 5 | * -> change the IP to something that works for you |
| tuxic | 0:5c9e0971532d | 6 | * -> connect to the mbed with a TFTP client in binary(octet) mode |
| tuxic | 0:5c9e0971532d | 7 | * -> use (s)uspend and (r)esume keys to turn TFTP server on/off |
| tuxic | 0:5c9e0971532d | 8 | * -> upload any file, but .bin files are always put on the internal |
| tuxic | 0:5c9e0971532d | 9 | * memory, as are config.txt files |
| tuxic | 0:5c9e0971532d | 10 | * |
