Hi all,

Some time ago there where a thread about the topic. Someone posted a network interface source file for the lpc17xx.  
Did anyone get it up running? In case so what is the status? (No need to try the same if already done)

Link to thread:

Hi Thomas,

In [mentioned thread](http://www.freertos.org/FreeRTOS_Support_Forum_Archive/March_2016/freertos_FreeRTOS_TCP_with_LPC17XX_9ed36a53j.html) I posted [NetworkInterface.c](https://sourceforge.net/p/freertos/discussion/382005/thread/9ed36a53/07c4/attachment/NetworkInterface.c) (10346 bytes).

Nobody seems to use it, or at least nobody responded. That version was developed for `FreeRTOS-Plus-UDP`, the UDP-only predecessor of `FreeRTOS-Plus-TCP`.

Feel free to try it out and post any questions you have. Unfortunately I only have LPC18xx hardware so I can not test it my self.

I don’t know what the status of that file is - but I have used the  
LPC17xx MAC in other projects and it was relatively simple, so if  
nothing else it will give you a starting point that can then just be  
refined.
