JuergenSchuele 8:0cfa131f854c 5 *
JuergenSchuele 8:0cfa131f854c 6 * Basic fuctionality:
JuergenSchuele 8:0cfa131f854c 7 * - Controls LED
JuergenSchuele 8:0cfa131f854c 8 * - Reads userbutton
JuergenSchuele 8:0cfa131f854c 9 * - Prints on serial terminal
JuergenSchuele 8:0cfa131f854c 10 * - Reads character from serial terminal
JuergenSchuele 11:9080f0d4fd85 11 *
JuergenSchuele 11:9080f0d4fd85 12 * To run the code on the mbed-simulator, change:
JuergenSchuele 11:9080f0d4fd85 13 - Change #define PRESSED 0 to 1
JuergenSchuele 11:9080f0d4fd85 14 - Delete the Serial pc object
JuergenSchuele 11:9080f0d4fd85 15 - substitute pc.printf() by printf()
