Greetings,

I am attempting to communicate with a Maxim/Dallas Semiconductor IC DS2438 (Smart Battery Monitor).  So far, when I attempt the reset, the return code indicates no devices on the 1 wire bus.  Here is the SX/B:

[code]
OneWireInitialize:
	OWRESET OneWireDQ,OneWireLow0
RETURN
[/code]

After this executes, the memory at OneWireLow0 contains 3 (no devices on the bus).  I have included a schematic.

I have been checking the obvious things like wiring and Maxim/Dallas application notes but so far nothing leaps out.  Anything else I might check?  Anyone using 1 wire devices?  Anyone using Maxim/Dallas 1 wire devices?
