- 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 -

- AltOS New Features -

- Add support for TeleGPS boards. -
- 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. -
- 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 -

- 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. -

- 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. -
- Increase the width of data lines in the graphs to make them - easier to read. -
- 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. -
- 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. -

- TeleGPS Application -

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

- 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. -
