public class OneWireContainer08

extends OneWireContainer

1-Wire container for 128 byte memory iButton, DS1992. This container encapsulates the functionality of the iButton family type 08 (hex)

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

Features

• 1024 bits (128 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
• Data integrity assured with strict read/write protocols
• Operating temperature range from -40°C to +70°C
• 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 128 starting at physical address 0
  • Features Read/Write general-purpose non-volatile
  • Pages 4 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.
