+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
