Enum Constant	Description
IGNORE_NAK	Ignores not acknowledge.
NO_READ_ACK	Ignores read acknowledge.
NO_START	Does not issue any more START/address after the initial START/address in a combined message.
READ	Is a read operation, not a write.
REVISE_RW_BIT	Sends a read flag for writes and a write flag for reads.
TEN_BIT_ADDRESSING	Uses 10-bit addressing scheme instead of 7-bit.

Enum Constant Detail

TEN_BIT_ADDRESSING

public static final I2CFlag TEN_BIT_ADDRESSING

Uses 10-bit addressing scheme instead of 7-bit.

READ

public static final I2CFlag READ

Is a read operation, not a write.

NO_START

public static final I2CFlag NO_START

Does not issue any more START/address after the initial START/address in a combined message.

This is a workaround for broken I2C slave devices.

REVISE_RW_BIT

public static final I2CFlag REVISE_RW_BIT

Sends a read flag for writes and a write flag for reads.

This is a workaround for broken I2C slave devices.

Check for the protocol mangling functionality.

IGNORE_NAK

public static final I2CFlag IGNORE_NAK

Ignores not acknowledge.

Check for the protocol mangling functionality.

NO_READ_ACK

public static final I2CFlag NO_READ_ACK

Ignores read acknowledge.

Check for the protocol mangling functionality.

Method Detail

values

public static I2CFlag[] 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 (I2CFlag c : I2CFlag.values())
    System.out.println(c);

Returns:

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

valueOf

public static I2CFlag 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
