Has there been made any port yet to the LPC17XX platform? I intend to use FreeRTOS+TCP with an LPC1769 on an own hardware platform. The LPCopen code does not seem to be maintained much so it would be nice if it was possible to use FreeRTOS+TCP instead.

You will find an old LPC17xx lwIP demo on the following link, but as you say, the driver standard is out of date too: http://www.freertos.org/FreeRTOS-Plus/FreeRTOSPlusIO/DemoApplications/LPCXpressoLPC1769/NXPLPC1769Demo_Description.shtml

There is a driver for the LPC18xx for FreeRTOS+TCP, but it has not been used in a while, and may therefore need a little tinkering to get it to build with the latest +TCP code.

Where can that driver for the LPC18xx be found?

I have attached what we have - note while this was working just fine some time ago, as you can see it was never completed, and may need work to use with the latest +TCP code. I hope it will be useful, but that's all....

A small correction on what Richard wrote. He attached this file:


which is from a very recent date, recently tested on a LPC1830, and compatible with the latest release of FreeRTOS+TCP. One of the users on this forum is adapting this LPC18xx/NetworkInterface.c to use it on a LPC43xx.

However, if I'm not mistaken, the EMAC of LPC18xx is not compatible with the EMAC of a LPC17xx.

I will attach the LPC17xx version. This version has not been tested for a long time. We only kept the naming of the functions up-to-date, so it should compile. But I guess that you will have some work on it before it runs. You can always write if you have more questions.

Hi Mike,

I pretend to use the same FreeRTOS+TCP with the LPC1769 CMSIS DAP REV. D. Did you success with making it work with the driver attached by Hein?
