Enum Constant Detail

• REPEAT

  public static final I2cDeviceSynch.ReadMode REPEAT

  Continuously issue I2C reads whenever there's nothing else needing to be done. In this mode, read() will not necessarily execute an I2C transaction for every call but might instead return data previously read from the I2C device. This mode is most useful in a device that spends most of its time doing read operations and only very infrequently writes, if ever.

  See Also:

  I2cDeviceSynchSimple.read(int, int)

• BALANCED

  public static final I2cDeviceSynch.ReadMode BALANCED

  Continuously issue I2C reads as in REPEAT when we can, but do not automatically transition back to read-mode following a write operation in order to do so. This mode is most useful in a device which has a balanced mix of read() and write() operations, such as a motor controller. Like REPEAT, this mode might return data that was previously read a short while ago.

• ONLY_ONCE

  public static final I2cDeviceSynch.ReadMode ONLY_ONCE

  Only issue a single I2C read, then set the read window to null to disable further reads. Executing a read() in this mode will always get fresh data from the I2C device.

Method Detail

• values

  public static I2cDeviceSynch.ReadMode[] 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 (I2cDeviceSynch.ReadMode c : I2cDeviceSynch.ReadMode.values())
      System.out.println(c);
  

  Returns:

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

• valueOf

  public static I2cDeviceSynch.ReadMode 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
