The OMAP is a ARM type processor from Texas Instruments that has 1-wire support built in.

The original support from Matthew Percival includes an excellent writeup. The actual module and approach is no longer current. The description of the 1-wire support errata and related hdq protocol.


Current OMAP 1-wire support is part of the wire1 (w1) subsystem. There currently are problems with the module and 1-wire support which is being investigated.
