Alexander Lang / Mbed 2 deprecated LEDFlash

A simple program to demonstrate how to use a RockerSW object on the 4D systems touch screen display with the mbed as a host microcontroller

Dependencies:   mbed

This is a demonstration program on how to use a 4D systems touch screen display with the mbed as a host microcontroller. For more information please take a look at the corresponding blog post here:
