Kyle Yancey / Mbed 2 deprecated SNES_Controller

This program uses a NUCLEO-F401RE to control an SNES console by sending the button states. (1 = Unpressed, 0 = Pressed) Data, Clock and Latch from the SNES must be connected to the appropriate pins. The NUCLEO is powered by the SNES through E5V. The power jumper should be moved to E5V configuration when powered by SNES.
