Try this:

Create a fake workspace and go in it

File -> Import -> General -> Existing project into workspace -> Select Archive File

My example path is:

/usr/local/lpcxpresso_8.2.2_650/lpcxpresso/Examples/LPCOpen

but your can be different

You can use example of board with MCU 1795, and file name is:

lpcopen_2_10_lpcxpresso_nxp_lpcxpresso_1769.zip

There is an DHPC webserver Example (if not It should be enable with define LWIP_DHCP)

Just take source code you need and fix it with you MCU.

Hi Walter Buttazzo,

Thanks for your support.

I am working on LPC43xx MCU, not LPC17xx MCU. It will be great if you support with LPC43xx MCU.

Thanks & Regards,

The same examples provided in the LPC4337 LPCOpen examples. Look in lpcopen_2_16_lpcxpresso_nxp_lpcxpresso_4337.zip

in the Examples/LPCOpen directory.
