Class OneWireContainer0A


  • public class OneWireContainer0A
    extends OneWireContainer

    1-Wire container for 2048 byte memory iButton, DS1995. This container encapsulates the functionality of the iButton family type 0A (hex)

    This iButton is primarily used as a read/write portable memory device.

    Features

    • 16384 bits (2048 bytes) of read/write nonvolatile memory
    • 256-bit (32-byte) scratchpad ensures integrity of data transfer
    • Memory partitioned into 256-bit (32-byte) pages for packetizing data
    • Overdrive mode boosts communication to 142 kbits per second
    • Data integrity assured with strict read/write protocols
    • Operating temperature range from -40@htmlonly °C @endhtmlonly to +70@htmlonly °C @endhtmlonly
    • Over 10 years of data retention

    Memory

    The memory can be accessed through the objects that are returned from the getMemoryBanks method.

    The following is a list of the MemoryBank instances that are returned:
    • Scratchpad
      • Implements MemoryBank, PagedMemoryBank
      • Size 32 starting at physical address 0
      • Features Read/Write not-general-purpose volatile
      • Pages 1 pages of length 32 bytes
      • Extra information for each page Target address, offset, length 3
    • Main Memory
      • Implements MemoryBank, PagedMemoryBank
      • Size 2048 starting at physical address 0
      • Features Read/Write general-purpose non-volatile
      • Pages 64 pages of length 32 bytes giving 29 bytes Packet data payload

    Usage

    See the usage example in OneWireContainer to enumerate the MemoryBanks.
    See the usage examples in MemoryBank and PagedMemoryBank for bank specific operations.

    • Constructor Detail

      • OneWireContainer0A

        public OneWireContainer0A()
        Create an empty container that is not complete until after a call to setupContainer.

        This is one of the methods to construct a container. The others are through creating a OneWireContainer with parameters.

        super.setupContainer()
      • OneWireContainer0A

        public OneWireContainer0A​(DSPortAdapter sourceAdapter,
                                  byte[] newAddress)
        Create a container with the provided adapter instance and the address of the iButton or 1-Wire device.

        This is one of the methods to construct a container. The other is through creating a OneWireContainer with NO parameters.

        Parameters:
        sourceAdapter - adapter instance used to communicate with this iButton
        newAddress - Address of this 1-Wire device

        Create a container with the provided adapter instance and the address of the iButton or 1-Wire device.

        This is one of the methods to construct a container. The other is through creating a OneWireContainer with NO parameters.

        Parameters:
        sourceAdapter - adapter instance used to communicate with this 1-Wire device
        newAddress - Address of this 1-Wire device
