... Anyway the DS2760 starts out in a sleep mode and here is what you need
to do to get it out of sleep mode.
Connect up the Moisture Meter to the 1-Wire network and start the
OneWireViewer. Go to the memory tab and click on the "EEPROM memory for
DS2760" entry in the Banks pane. Then in the Contents pane you will see 2
pages (page 0 and page 1). The first line on page 1 will show 03 00 00 00 00
00 00 00. You need to change the first set of zeros after the 03 to 20. The
line should now read 03 20 00 00 00 00 00 00. Once you have changed that
click the Commit Changes button, the status bar should read "Done committing
changes..." when it is complete. Once that is done then remove the Moisture
Meter from the 1-Wire network and external power for at least 2 seconds and
then connect it again. After you reconnect it all the readings should be
working. Let me know if this doesn't fix the problem.
-----------
In this case you would need to set the bit in byte 1 or page.1
Probably the easiest way to do it is with owhttpd, which handles binary data
more gracefully than the shell.
I'd like to create a single command to do this, "sleepmode"? It would
read/write bit 5 of 0x31. Does this make sense?
