The header file, lpc21xx.h, is the correct device specific header file when compiling a project for the LPC21XX series devices using uVision version 4.

I not yet installed version 5, so the advice I can offer is limited.

When you began the project, did you use the New uVision Project wizard?

Is the correct device chosen under project settings?

Zip up the entire project directory and upload it to the thread, maybe someone else is using version 5.

maybe is it for this reason?
MDK Version 5 uses Software Packs to support a microcontroller device and to use middleware. To maintain backward compatibility with MDK Version 4 you may install Legacy Support. This might be necessary for two reasons:
To maintain projects created with MDK Version 4 without migrating to Software Packs.
To use devices that are not yet supported by a Device Family Pack.
