NUTDEVICE devSpiMmcGpio

Multimedia card device information structure.

A pointer to this structure must be passed to NutRegisterDevice() to bind this driver to the Nut/OS kernel. An application may then call /verbatim _open("MMC0:", _O_RDWR | _O_BINARY); /endverbatim to mount the first active primary partition with any previously registered file system driver (typically devPhat0).

NUTSPINODE nodeSpiMmcGpio

Initial value:

 {
    NULL,           
    NULL,           
    SPI_MMC_CLK,    
    SPI_MODE_0,     
    8,              
    SPI_MMC_CS      
}

NPL SPI node implementation structure for MMC.
