|
|
* This demo application demonstartes Microchip TFTP client module usage |
|
|
* See TFTPDemo(), TFTPWrite() and TFTPRead() for actual implementation. |
|
|
* |
|
|
* This application monitors RB5 switch. On first push it |
|
|
* writes 'tftpwr.bin' file to server. tftpwr.bin file is made up of |
|
|
* first 16KB of program memory. |
|
|
* On second push, it reads 'tftprd.txt' file from server. |
|
|
* |
|
|
* Server IP address is set in "Board Setup" mode using Hyperterminal. |
|
|
* |
|
|
* It displays rotating '-' to indicate command in progress. |
|
|
* 'Y' to indicate success |
|
|
* 'N' for failure |
|
|
* 'T' for timeout |
|
|
* 'E' for error. |
|
|
* |
|
|
* |
|
|
* If running this applicaton on PICDEM.net use |
|
|
* HS Oscillator |
|
|
* Debug disabled |
|
|
* Low Voltage Disabled |
|
|
* Watchdog timer disabled |
