FRDM-K64F Code Share / Mbed 2 deprecated frdm_K64F_Controller

Lets you control the FRDM-K64F board over the PC using the GUI software (https://github.com/navin-bhaskar/Controller) written in Python. To use the software, connect the FRDM-K64Fto your PC (via USB cable connected to USB port labelled as "open SDA") and start the software to control the FRDM-K64F. For more info on usage, please go to: http://navinbhaskar.blogspot.in/2013/02/arduino-controller-3.html

Dependencies:   mbed
