Igor Skochinsky / Mbed 2 deprecated DriverLibrary

NXP's driver library for LPC17xx, ported to mbed's online compiler. Not tested! I had to fix a lot of warings and found a couple of pretty obvious bugs, so the chances are there are more. Original: http://ics.nxp.com/support/documents/microcontrollers/zip/lpc17xx.cmsis.driver.library.zip

Dependencies:   mbed

Embed: (wiki syntax)
