Enum SpiClockMode

  • All Implemented Interfaces:
    Serializable, Comparable<SpiClockMode>

    public enum SpiClockMode
    extends Enum<SpiClockMode>
    SPI clock mode determines the clock polarity and phase with respect to data. See SPI clock polarity and phase. ARM-based MCU use the following mode numbers. Examine the device datasheet to understand the clock mode or modes supported.
     SPI  Clock Polarity Clock Phase Clock Edge
     Mode (CPOL/CKP)     (CPHA)      (CKE/NCPHA)
     0    0              0           1
     1    0              1           0

    • Method Detail

      • values

        public static SpiClockMode[] values()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
        for (SpiClockMode c : SpiClockMode.values())
            System.out.println(c);
        
        Returns:
        an array containing the constants of this enum type, in the order they are declared
      • valueOf

        public static SpiClockMode valueOf​(String name)
        Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
        Parameters:
        name - the name of the enum constant to be returned.
        Returns:
        the enum constant with the specified name
        Throws:
        IllegalArgumentException - if this enum type has no constant with the specified name
        NullPointerException - if the argument is null
