Compiling the demo from the [FreeRTOS.org](http://FreeRTOS.org) website on the LPC1768-SK board using IAR 5.4. It compiles downloads fine, LED 1 blinks every second. The USB works fine, I can send receive characters via RealTerm. But the webserver portion is not working, I set the IP address to match mine, except for the last three digits of course. For the last three digits I ping an address that doesn’t respond (i.e. …254 is what I am using because it seemed to be unused). Then I compile and download (after entering this address in FreeRTOSConfig.h see below). I am using this at work, and I am hoping to avoid contacting IT, they are such a pain in the aassss to work with (they’re always so intimidated by EEs’ whats with that anyway?). ``` /*-------------------------------------------- Microsoft Windows XP [Version 5.1.2600] (C) Copyright 1985-2001 Microsoft Corp.
