Date: March 20, 2011 This library is created from "LPC17xx CMSIS-Compliant Standard Peripheral Firmware Driver Library (GNU, Keil, IAR) (Jan 28, 2011)", available from NXP's website, under "All microcontrollers support documents" [[http://ics.nxp.com/support/documents/microcontrollers/?type=software]] You will need to follow [[/projects/libraries/svn/mbed/trunk/LPC1768/LPC17xx.h]] while using this library Examples provided here [[/users/frank26080115/programs/LPC1700CMSIS_Examples/]] The beautiful thing is that NXP does not place copyright protection on any of the files in here Only a few modifications are made to make it compile with the mbed online compiler, I fixed some warnings as well. This is untested as of March 20, 2011 Forum post about this library: [[/forum/mbed/topic/2030/]]
