Macro Definition Documentation

SD_SCK_HZ

#define SD_SCK_HZ

(

maxSpeed

)

SPISettings(maxSpeed, MSBFIRST, SPI_MODE0)

SPISettings for SCK frequency in Hz.

SD_SCK_MHZ

#define SD_SCK_MHZ

(

maxMhz

)

SPISettings(1000000UL*maxMhz, MSBFIRST, SPI_MODE0)

SPISettings for SCK frequency in MHz.

SPI_DIV3_SPEED

#define SPI_DIV3_SPEED   SD_SCK_HZ(F_CPU/3)

Set SCK rate to F_CPU/3 for Due
