Enum Constants

Enum Constant	Description
MODE_0	Clock phase is configured such that data is sampled on the rising edge of the clock pulse and shifted out on the falling edge of the clock pulse.
MODE_1	Clock phase is configured such that data is sampled on the falling edge of the clock pulse and shifted out on the rising edge of the clock pulse.
MODE_2	Clock phase is configured such that data is sampled on the falling edge of the clock pulse and shifted out on the rising edge of the clock pulse.
MODE_3	Clock phase is configured such that data is sampled on the rising edge of the clock pulse and shifted out on the falling edge of the clock pulse.

Enum Constant Detail

MODE_0

public static final SpiMode MODE_0

Clock phase is configured such that data is sampled on the rising edge of the clock pulse and shifted out on the falling edge of the clock pulse. Note that data must be available before the first rising edge of the clock.

MODE_1

public static final SpiMode MODE_1

Clock phase is configured such that data is sampled on the falling edge of the clock pulse and shifted out on the rising edge of the clock pulse.

MODE_2

public static final SpiMode MODE_2

Clock phase is configured such that data is sampled on the falling edge of the clock pulse and shifted out on the rising edge of the clock pulse. Note that data must be available before the first falling edge of the clock.

MODE_3

public static final SpiMode MODE_3

Clock phase is configured such that data is sampled on the rising edge of the clock pulse and shifted out on the falling edge of the clock pulse.

Method Detail

values

public static SpiMode[] 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 (SpiMode c : SpiMode.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static SpiMode valueOf(java.lang.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:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

toValue

public java.lang.Integer toValue()

Specified by:

toValue in interface GlcdOptionValue<java.lang.Integer>

getType

public java.lang.Class<java.lang.Integer> getType()

Specified by:

getType in interface GlcdOptionValue<java.lang.Integer>
