Hello! I started a new application (solar home energy monitoring) which uses
the mighty DS2423 (as purchased from Digi-Key & Hobby Boards) on a Raspberry Pi
with the Sheepwalk RPI2 bus master and I2C-1 driver.
The DS2423 is reading the output of a YF-S201 flow meter so I can see how much
hot water the house is using.
Here is a screendump of the owhttpd output:

(although I'm reading it with owread.)
Yesterday, for fun, I replaced the "memory" field with
0000DEAD0BEEF0CAFE00000
... and all the rest zeros - I just pasted in zeros until it was full. After
that, the counter started... well, not counting. Or counting 1 for every few
thousand pulses or something. I used the "upload" function to refill it with
some random data (a small jpg of a kitten) and it seems to be back to normal.
I have two questions:
1) could the contents of "memory" or the act of pasting data in there have
affected how the DS2423 counts? and
2) what should be in the "mincount" field? It was oddly at "1723" when I
looked at it (after the trouble began) and I reset it to zero but... what
should it be?
Many thanks.
