Version 1.2 is a minor release. It provides a few new features in AltosUI
and the AltOS firmware and fixes bugs.
AltOS Firmware Changes
In TeleMini recovery mode (when booted with the outer two
debug pins connected together), the radio parameters are also
set back to defaults (434.550MHz, N0CALL, factory radio cal).
Add support for reflashing the SkyTraq GPS chips. This
requires special host-side code which currently only exists
for Linux.
Add MicroPeak support. This includes support for the ATtiny85
processor and adaptations to the core code to allow for
devices too small to run the multi-tasking scheduler.
Correct Kalman filter model error covariance matrix. The
values used previously assumed continuous measurements instead
of discrete measurements.
AltosUI Changes
Handle missing GPS lock in 'Descent' tab. Previously, if the
GPS position of the pad was unknown, an exception would be
raised, breaking the Descent tab contents.
Add preliminary MegaMetrum support, including configuration,
data download and analysis.
Improve the graph, adding tool-tips to show values near the
cursor and making the displayed set of values configurable,
adding all of the flight data as options while leaving the
default settings alone so that the graph starts by showing
height, speed and acceleration.
Make the initial position of the AltosUI top level window
configurable. Along with this change, the other windows will
pop up at 'sensible' places now, instead of on top of one
another.
Add callsign to Monitor idle window and connecting
dialogs. This makes it clear which callsign is being used so
that the operator will be aware that it must match the flight
computer value or no communication will work.
When downloading flight data, display the block number so that
the user has some sense of progress. Unfortunately, we don't
know how many blocks will need to be downloaded, but at least
it isn't just sitting there doing nothing for a long time.
Add GPS data and a map to the graph window. This lets you see
a complete summary of the flight without needing to 'replay'
the whole thing.
Distribution Changes
Distribute Mac OS X packages in disk image ('.dmg') format to
greatly simplify installation.
Provide version numbers for the shared Java libraries to
ensure that upgrades work properly, and to allow for multiple
Altus Metrum software packages to be installed in the same
directory at the same time.
