-1-Wire protocol decoder.
-
-The 1-Wire protocol enables bidirectional communication over a single wire (and
-ground) between a single master and one or multiple slaves. The protocol is
-layered.
-- Link layer (reset, presence detection, reading/writing bits)
-- Network layer (skip/search/match device ROM addresses)
-- Transport layer (transport data between 1-Wire master and device)
-
-Transport layer
-
-The transport layer is the largest and most complex part of the protocol, since
-it is very device specific. The decoder is parsing only a small part of the
-protocol.
-
-Annotations:
-The next link layer annotations are shown:
-- RESET/PRESENCE True/False
- The event is marked from the signal negative edge to the end of the reset
- high period. It is also reported if there are any devices attached to the
- bus.
-The next network layer annotations are shown:
-- ROM val
- The 64bit value of the addressed device is displayed:
- family code (1B) + serial number (6B) + CRC (1B)
-- FUNCTION COMMAND val name
- The requested FUNCTION command is displayed as an 8bit HEX value and by name.
-- DATA val
- Data intended for the transport layer is displayed as an 8bit HEX value.
-
-TODO:
-- add CRC checks for transport layer
