FYI, a new, universal driver platform is currently under development which will eventually obsolete the PDLs and other code bundles. It is called LPCOpen Platform and the first (alpha) version can be found here: http://www.lpcware.com/content/project/lpcopen-platform-nxp-lpc-microcontrollers. It will include newly written and optimized drivers for all parts we produce. Look for the next release in a month or so.
