Test of Embedded Artists LPCXpresso baseboard SD card and ethernet facilities. This program downloads files from a website to the SD card. This program now uses the HTTPClient from: http://mbed.org/users/donatien/programs/HTTPClient/latest which downloads the files without errors. The previous version of this program was used to demonstrate that an earlier HTTPClient downloaded files with errors.

Dependencies:   EthernetNetIf mbed

+/*
+ Demo of Embedded Artists LPCXpresso baseboard SD card and ethernet facilities.
+
+ This program downloads three files from a website to the SD card.
+ 
+ SD Card setup:
+ 
+ 1. Insert all five jumpers in J39 as described in section 4.3.3
+ of base board users guide.
+ 
+ 2. Remove jumper marked "A" in J55 In order to connect PIO1_11 
+ to CS signal of J40 (the SPI-SSEL signal)  as described in section 4.3.3
+ of base board users guide.
+ 
+ Please note that there seems to be some problem with the libraries used.  This program
+ downloads the files to the SD card but often looses some of the file data.
