Shields / Mbed 2 deprecated Seeed_SDCard_Shield

Example program for SD card shield on SPI pins D10-D13

Dependencies:   SDFileSystem mbed

The program uses the standard Arduino shields SPI pins:

SignalPin
SCKD13
MISOD12
MOSID11
CSD10

Note that this shield doesn't use the standard SPI pins, but relies on non-standard 6-pin SPI header located at the shield bottom. To make it work you will have to bridge those pins as shown on the image (the green SPI pins).

SignalPin 1Pin 2
MOSID11SPI4
MISOD12SPI1
SCKD13SPI3
CSD10D4
