SD card interfacing

Hi,

I have written SD & SDHC card routine for reading, writing and erasing data from SD card. It used the hardware SPI of nRF51822.

NOTE:

1)Define the PINs of SD card first before initialing.

2)Define MOSI, MISO and SCK pins only, define the CS pin to some other pin that is not being used( these pin are define in spi_master_config.h )

3)CS pin should be separately define in SD_Routines.c by the name #define MMCSD_PIN_SELECT 29

4)If you are facing problem in using my library then first test you SPI separately.

SD_Routines.c SD_Routines.h
