Class SPISettings

SPISettings Class

A class to set SPI parameters.

class SPISettings

Public Constructors
SPISettings::SPISettings	Create a SPISettings object and set SPI clock speed, bit order and data mode

Construct an object and configure SPI parameters — clock speed, bit order and data mode to the preferred default value.

SPISettings(uint32_t clock, BitOrder bitOrder, uint8_t dataMode)

clock: SPI clock speed in Hz. Default value is 4000000.

bitOrder: The bit order of transmitting command/address/data. Default value is MSBFIRST.

MSBFIRST (MSB: Most Significant Bit)

LSBFIRST (LSB: Least Significant Bit)

dataMode: SPI has four modes that correspond to the four possible clocking configurations. Default value is SPI_MODE0.

SPI_MODE0, SPI_MODE1, SPI_MODE2, SPI_MODE3

Important

This class seldom used alone, it is always used with beginTransaction() as a parameter in SPIClass.

Note

“SPI.h” must be included to use the class function.
