Test of Embedded Artists LPCXpresso baseboard ethernet, SD card, audio and OLED display facilities. The program displays the day, date and time on the baseboard OLED and sounds the Big Ben chimes on the hour and quarter hour. On initial startup the program checks that the mbed clock is set and that the chime wav files can be accessed on the SD card. If not it asks to be connected to the internet to obtain the current time and to download the wav files to the SD card.
