OVERVIEW

This nn article to hold notes on NXP/LPCXpresso programming tools and methods. Expet tools to include LPCXpresso Integrated Development Environment and command line based gcc, g++, as, ld, objcopy and related tools. Programming methods expected to include FTDI cable based programming employed with FlashMagic and lpc21isp. More to come going forward . . .
