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 FatFileSystem HTTPClient mbed
