SD card interfacing

10 Oct 2014

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

Just mentioning that the newest SDK (12.2.0) has support for SD cards. I advise you to take a look at the SD card example here. If you have questions to the SD card library/example in the SDK, you can post a question on the forum and we will help you. The SD card library in the SDK is also based on FATFS.
