SPI Interface – Memory Card 5.2.
The DIABLO16 supports SD, micro-SD and MMC
memory cards via its dedicated hardware SPI
interface. The DIABLO16 has 4 SPI channels, and
the first is dedicated for this. The memory card is
used for all multimedia file retrieval such as
images, animations and movie clips and the SPI
interface is dedicated for this purpose only. The
memory card can also be used as general purpose
storage for data logging applications (RAW and
FAT16 format support). Support is available for
micro-SD with up to 2GB capacity and for high
capacity HC memory cards starting from 4GB and
above.
SDI pin (SPI Serial Data In):
The SPI Serial Data Input (SDI). SD memory card
use only. Connect this pin to the SPI Serial Data
Out (SDO) signal of the memory card.
SDO pin (SPI Serial Data Out):
The SPI Serial Data Output (SDI). SD memory card
use only. Connect this pin to the SPI Serial Data In
(SDI) signal of the memory card.
SCK pin (SPI Serial Clock):
The SPI Serial Clock output (SCK). SD memory card
use only. Connect this pin to the SPI Serial Clock
(SCK) signal of the memory card.
SDCS pin (SD Memory Card Chip Select):
SD Memory-Card Chip Select (SDCS). SD memory
card use only. Connect this pin to the Chip Enable
(CS) signal of the memory card.
