Paul
I've just installed via cvs and it is now working....alittle hard to increment
my counters at the moment as they are connected to water flow meters...however
the values look OK. I'll get some water flow happening tomorrow night and test
to see the counters increment, however I assume if I see the correct counter
values I presume its OK ?
thanks alot for your assistance
cheers

Just reloaded 2.5p10 and these are the counter values displayed via owhttpd
Counter A = 8999689
That's 00 89 53 09 in hex.
Counter B = 2718957568
That's A2 10 00 00 in hex.

Hmm... Should be 4 bytes of counter and 4 bytes of zero.
Any idea what your counters should read?
Well, the 00 00 10 A2 comes out correct, but that 04 following is supposed to
be 00 according to the datasheet:
http://datasheets.maxim-ic.com/en/ds/DS2423.pdf page 8.
I suppose we could just ignore the test for the zero in the datasheet. Note
that the whole field was confirmed by a CRC16 generated by the DS2423.
So try the newest CVS version, that ignores zero checks and see if counting
seems sequential. That's my concern, that we have
the byte order wrong.
