Version 1.4 is a major release. It includes support for our new
TeleGPS product, new features and bug fixes in in the flight
software for all our boards and the AltosUI ground station
</p><p>
AltOS New Features
</p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem"><p>
Add support for TeleGPS boards.
</p></li><li class="listitem"><p>
Replace the 'dit dit dit' tones at startup with the current
battery voltage, measured in tenths of a volt. This lets you
check the battery voltage without needing telemetry, which
is especially useful on EasyMini.
</p></li><li class="listitem"><p>
Change state beeping to "Farnsworth spacing", which means
they're quite a bit faster than before, and so they take
less time to send.
</p></li><li class="listitem"><p>
Make the beeper tone configurable, making it possible to
distinguish between two Altus Metrum products in the same ebay.
</p></li><li class="listitem"><p>
Make the firing time for extra pyro channels configurable,
allowing longer (or shorter) than the default 50ms. Only relevant
for TeleMega at this time.
</p></li></ul></div><p>
</p><p>
AltOS Fixes
</p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem"><p>
Fix bug preventing the selection of the 'Flight State After'
mode in pyro configuration.
</p></li><li class="listitem"><p>
Fix bug where erasing flights would reset the flight number
to 2 on TeleMega and TeleMetrum v2.
</p></li><li class="listitem"><p>
Fix u-Blox GPS driver to mark course and speed data as being
present.
</p></li></ul></div><p>
</p><p>
AltosUI New Features
</p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem"><p>
Add zooming and new content types (terrain and road maps) to
map view. Change map storage format from PNG to Jpeg, which
saves a huge amount of disk space. You will need to
re-download all of your pre-loaded map images.
</p></li><li class="listitem"><p>
Add a distance measuring device to the maps view. Select
this by using any button other than the left one, or by
pressing shift or control on the keyboard while using the
left button.
</p></li><li class="listitem"><p>
Add new 'Ignitor' tab to the flight monitor display for
TeleMega's extra ignitors.
</p></li><li class="listitem"><p>
Increase the width of data lines in the graphs to make them
easier to read.
</p></li><li class="listitem"><p>
Add additional ignitor firing marks and voltages to the
graph so you can see when the ignitors fired, along with
the ignitor voltages.
</p></li><li class="listitem"><p>
Add GPS course, ground speed and climb rate as optional
graph elements.
</p></li></ul></div><p>
</p><p>
AltosUI Fixes
</p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem"><p>
When flashing new firmware, re-try opening the device as
sometimes it takes a while for the underlying operating
system to recognize that the device has rebooted in
preparation for the flashing operation.
</p></li><li class="listitem"><p>
Hide Tilt Angle in ascent tab for devices that don't have a gyro.
</p></li><li class="listitem"><p>
Filter out speed and acceleration spikes caused by ejection
charge firing when computing the maximum values. This
provides a more accurate reading of those maximums.
</p></li><li class="listitem"><p>
Fix EasyMini voltage displays. Early EasyMini prototypes
used a 3.0V regulator, and AltosUI still used that value as
the basis of the computation. Production EasyMini boards
have always shipped with a 3.3V regulator. Also, purple
EasyMini boards sensed the battery voltage past the blocking
diode, resulting in a drop of about 150mV from the true
battery voltage. Compensate for that when displaying the
value.
</p></li><li class="listitem"><p>
Display error message when trying to configure maximum
flight log size while the flight computer still has flight
data stored.
</p></li><li class="listitem"><p>
Handle TeleMetrum and TeleMini eeprom files generated with
pre-1.0 firmware. Those ancient versions didn't report the
log format, so just use the product name instead.
</p></li></ul></div><p>
</p><p>
TeleGPS Application
</p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem"><p>
New application designed for use with TeleGPS boards.
</p></li><li class="listitem"><p>
Shares code with AltosUI, mostly just trimmed down to focus
on TeleGPS-related functions.
</p></li></ul></div><p>
</p><p>
Documentation changes
</p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem"><p>
Re-create the drill template images; they should print
correctly from Firefox at least. Ship these as individual
PDF files so they're easy to print.
</p></li><li class="listitem"><p>
Add a description of the 'Apogee Lockout' setting, which
prevents the apogee charge from firing for a configurable
amount of time after boost.
</p></li></ul></div><p>
