/*
 Demo of Embedded Artists LPCXpresso baseboard ethernet and OLED display facilities.

 Uses HTTP client to obtain the current time and displays the day, date and time on the OLED display.
 
 Based on RTCsetwithHTTPClient by nucho.

 NOTE: The LCPXpresso board does not provide the data/command signal to the mbed.
 To provide this signal please connect a jumper wire from PIO2_7 of baseboard mbed socket
 (empty 2nd hole below mbed pin 21) to  to PIO2_5 (on J6 right side ninth hole from bottom). 
 
 All jumpers on the board can be left in the default locations.
