One can also use the DS2480 to offload a bunch of the protocol, but again that's a lot of hassle unless you're using a lot of 1-wire. The 3-wire interface might be easier in many cases, although it dedicates the pins. Nevertheless, the DS1306 mentioned in another post seems like it may be even easier to use. --Bob -- ============================================================ Bob Drzyzgula It's not a problem bob@drzyzgula.org until something bad happens ============================================================
