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

| tom_coxon | 0:1b55f626a40f | 6 | SD Card setup: |
| tom_coxon | 1:0734a7b0fd5e | 7 | |
| tom_coxon | 0:1b55f626a40f | 8 | 1. Insert all five jumpers in J39 as described in section 4.3.3 |
| tom_coxon | 0:1b55f626a40f | 9 | of base board users guide. |
| tom_coxon | 1:0734a7b0fd5e | 10 | |
| tom_coxon | 1:0734a7b0fd5e | 11 | 2. Remove jumper marked "A" in J55 In order to connect PIO1_11 |
| tom_coxon | 0:1b55f626a40f | 12 | to CS signal of J40 (the SPI-SSEL signal) as described in section 4.3.3 |
| tom_coxon | 0:1b55f626a40f | 13 | of base board users guide. |
| tom_coxon | 1:0734a7b0fd5e | 14 | |
| tom_coxon | 1:0734a7b0fd5e | 15 | Now uses the HTTPClient from http://mbed.org/users/donatien/programs/HTTPClient/latest |
| tom_coxon | 1:0734a7b0fd5e | 16 | which downloads the files without errors. |
