The MMC/SD memory cards have several communication protocols (some of which are optional), particularly the SD (Secure Digital) memories always support the SPI protocol.

In this example, we want to use the new Microchip TCP/IP functionalities to permit to FTPMicro an e-mail to verify itself by a given event.

To store files in the SD card, a FAT Filesystem is used, so they can be written directly from a PC.
