Daniel Hadad / TFC-TEST

An example program that uses FRDM-TFC library written by Eli Hughes.

Dependencies:   FRDM-TFC

In order to make the FRDM-TFC library more portable by other programs, the main.cpp has been removed from it and placed in this example / demo program that uses it.

main.cpp@0:6432166d0781, 2014-04-15 (annotated)
