LPc18xx EMAC with LPCOpen

Posted by koenvda on February 16, 2017


I'm implementing FreeRTOS plus UDP on a LPC1830. As the network interface i want to use the LPCOpen Library which are include in the FreeRTOS-Plus-UDP lib. But i am struggling to use the lpc18xx43xxEMAC_LPCOpen files error free in the project. Is there a guide or maybe a new demo because the include demo is using the CMSISv2.10 DriverLib.

Hi Koen, FreeRTOS-Plus-UDP receives less of our attention because it has been replaced/upgraded by the more complete FreeRTOS+TCP. It comes with a LPC18xx driver (NetworkInterface.c) that should work well. You can download the demo FreeRTOS_Plus_TCP_and_CLI_LPC1830_CrossWorks_LPCXpresso and see how the project is setup.

If you find problem with that solution, please let it know.

Hi Hein,

Thanks for the reaction but where can i find the demo project?

You can download the FreeRTOS+TCP sources from http://www.freertos.org/FreeRTOS-Plus/FreeRTOSPlusTCP/index.html

You will find the demo in FreeRTOS-Plus/Demo/FreeRTOS_Plus_TCP_and_CLI_LPC1830_CrossWorks_LPCXpresso

The latest kernel is included in the ZIP file. Or you can use any of the newer kernels, 8.2 or higher.

If i donwload the sources there is no LPC1830 demo inside it. There are only TCP and FAT demos but not for the LPC1830. I don't see the TCP and CLI files.

Oops, you're right! It has not been added to the ZIP. I'm not sure for what reason. Would you mind to send me an email ( h point tibosch (at) freertos point org ), then I'll send you the demo project and help you get through it. I do have an LPCXpresso board, but it's been a while that I tested mentioned demo. Regards.
