M BERNSTEIN / Mbed 2 deprecated Original_Blinky_LED

This program is a replacement candidate for the original "Blinky LED" demo program which is stored on the STM32F401 Nucleo board, as shipped. Note that the original demo program is, as are all subsequent programs which are flashed to the board, replaced by a later program deposited on the Nucleo which is then loaded by the Nucleo for execution.

STM32F401 Nucleo :: A replacement "Blinky LED" program, similar to the original demo program flashed on the board as shipped. Note that the original demo is erased after a later program is stored and so is not retrievable.
