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 .wav 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.

 Now uses the HTTPClient from http://mbed.org/users/donatien/programs/HTTPClient/latest
 which downloads the files without errors.
