Hi,
It is necessary to import the LPCOpen Chip Library for the device used and optionally the LPCOpen Board Library Project. For do that it is necessary to follow these steps:
1. Click on Import project(s).

2. Select the examples archive file to import. In this case, the projects imported are contained within archives .zip.

3. For this example the LPC11U14 LPCXpresso board is selected. Click Open. Then click Next

4. Select only the LPCOpen Chip Library and LPCOpen Board Library Project. Click Finish.

The same steps are required for any LPC device and board you are used.
Have a great day,
Sol
