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

1. AltOS

AltOS new features:

-Add support for TeleGPS boards. -
-Make the beeper tone configurable, making it -possible to distinguish between two Altus Metrum -products in the same ebay. -
-Make the firing time for extra pyro channels -configurable, allowing longer (or shorter) than the -default 50ms. Only relevant for TeleMega at this -time. -

AltOS fixes:

-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. -
-Change state beeping to "Farnsworth spacing", which -means they’re quite a bit faster than before, and so -they take less time to send. -
-Fix bug preventing the selection of the Flight -State After mode in pyro configuration. -
-Fix bug where erasing flights would reset the flight -number to 2 on TeleMega and TeleMetrum v2. -
-Fix u-Blox GPS driver to mark course and speed data -as being present. -

2. AltosUI Application

AltosUI new features:

-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. -
-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. -
-Add new Ignitor tab to the flight monitor display -for TeleMega’s extra ignitors. -
-Add additional ignitor firing marks and voltages to -the graph so you can see when the ignitors fired, -along with the ignitor voltages. -
-Add GPS course, ground speed and climb rate as -optional graph elements. -

AltosUI fixes:

-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. -
-Hide Tilt Angle in ascent tab for devices that don’t -have a gyro. -
-Increase the width of data lines in the graphs to -make them easier to read. -
-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. -
-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. -
-Display error message when trying to configure -maximum flight log size while the flight computer -still has flight data stored. -
-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. -

3. TeleGPS Application

-New application designed for use with TeleGPS boards. -
-Shares code with AltosUI, mostly just trimmed down -to focus on TeleGPS-related functions. -

4. Documentation

Documentation changes:

-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. -
-Add a description of the Apogee Lockout setting, -which prevents the apogee charge from firing for a -configurable amount of time after boost. -
