Hi Vasi,

Can you confirm that thermometer.jal is intended for a single device
on the 1wire bus and thermometer2.jal potentially supports more
devices?
If so, it is probably best to start a test file with thermometer that
shows the use of all the relevant functions of the lib. There are
quite a few procedures and there function is 'quite briefly'
documented and not shown in the samples. And the ones that are used,
have no explanation (in contrast to the lcd use ;). So some work to
do.

An other thing is the parameter max_crc_errors. I think this is the
maximum number of retries. Correct?
Such a parameter suggests crc errors are quite common. How often do
you get CRC errors? Also, does it make sense to pass this as a
parameter? If it is a fixed value, we could add a constant. But when
there is a limited number of retries, there remains a chance that get
invalid reading back. And how would you act upon this? Maybe it makes
more sense to have a constant that either says unlimited retries or no
(automatic) retries at all, but return a succes indicator. If your
program has to handle the error, it will probably has some retry
mechanism anyway. Or do I miss something?

Once the first test-file is done,  it would be good to create a second
one to show the use of multiple devices on the bus. Are you able to
create a program (like termometer2) which works with two (or more)
devices on the same bus? Does the library support discovery of devices
on such a bus or should one first determine the ID of each device when
they are alone?
