I released the first pre version of myTemp 4.0 on Sunday. It still
lacks some of the features, 3.10 has, but I would like to give an
overview of what will be new, changed, improved.

I started working on myTemp again, since I changed my Linux Kernel
from 2.4.23 to 2.6.0 and obviously something changed in the serial
port drivers, which prevented version 3.10 of myTemp to work in the
emulator.

current state of the prerelease
-------------------------------
- graphical display of the temperature log
This works in the prerelease. Scaling of the axes and a grid are
still missing.

- background logging
Instead of having the Palm running throughout the logging, an alarm
is set for every sample, then the Palm wakes up, does the measurement
and goes to sleep again. (One cannot determine, if the Palm was
running or sleeping, when the alarm occured, since PalmOS does not
provide a way to do so. (Or I've been to stupid to find it.) This
means you have to set the sleep-time in the PalmOS Preferences to get
the handheld to sleep again.) The battery runtime of the palm should
be greatly improved by this and is now mainly dependent of the
measurement frequency.

- improved timing and locking
The low- and application level drivers for the 1-Wire bus have been
cleaned up. One result of it is, that you can use your palm, while it
is logging, since the temperature conversation doesn't lock up the
device for such a long time, like version 3.10. (probably you will
notice a short interruption every time the palm reads the
temperature)

- if the snd checkbox is marked, the palm will beep whenever a
temperature conversation occurs

- I wrote a small perl script (using the Palm:PDB perl-module), that
can extract temperatures directly from the .pdb-file. No need to
transfer it to the Memo application any more.

this will be in the final release=20
---------------------------------
(this means it is missing in the prerelease)

- support for mutliple sensors

- names for sensors
this allows you to name the different sensors to distinguish between
them

- live graphic update
Redraw the temperature graph in the application after a measurement
took place.

- display of the actual temperature

- support for big databases
Version 4.0 will allow up to 7 million temperature values in one
database, presumed one has 4GB of RAM inside the handheld. :-)

- some statistic is made, like the number of failed measurements

future releases
---------------
the following features are planed to be implemented in the future,
after version 4.0 has been released

- user defined scaling of the graph
- table view (to let you change between the view like in version 3.10
and the graphical view of version 4.0)
- support to store databases

NOTICE: Before installing the prerelease, you'll have to delete the
old version of myTemp, since the database formats are not compatible
and there's no conversion inside the application.

Sourceforge provides the possibility to make donations to projects
they host. So if you use and like myTemp, no one can stop you from
making a donation on the myTemp project page. ;-) It supports me
improving the myTemp project.

Merry Christmas to all of you,
