Version 1.1.1 is a bug-fix release. It fixes a couple of bugs -in AltosUI and one firmware bug that affects TeleMetrum -version 1.0 boards. Thanks to Bob Brown for help diagnosing -the Google Earth file export issue, and for suggesting the -addition of the Ground Distance value in the Descent tab.

1. AltOS

AltOS fixes:

-TeleMetrum v1.0 boards use the AT45DB081D flash -memory part to store flight data, which is different -from later TeleMetrum boards. The AltOS v1.1 driver -for this chip couldn’t erase memory, leaving it -impossible to delete flight data or update -configuration values. This bug doesn’t affect newer -TeleMetrum boards, and it doesn’t affect the safety -of rockets flying version 1.1 firmware. -

2. AltosUI

AltosUI new features:

-The “Descent” tab displays the range to the rocket, -which is a combination of the over-the-ground -distance to the rockets current latitude/longitude -and the height of the rocket. As such, it’s useful -for knowing how far away the rocket is, but -difficult to use when estimating where the rocket -might eventually land. A new “Ground Distance” field -has been added which displays the distance to a spot -right underneath the rocket. -

AltosUI fixes:

-Creating a Google Earth file (KML) from on-board -flight data (EEPROM) would generate an empty -file. The code responsible for reading the EEPROM -file wasn’t ever setting the GPS valid bits, and so -the KML export code thought there was no GPS data in -the file. -
-The “Landed” tab was displaying all values in metric -units, even when AltosUI was configured to display -imperial units. Somehow I just missed this tab when -doing the units stuff. -
-Sensor data wasn’t being displayed for TeleMini -flight computers in Monitor Idle mode, including -things like battery voltage. The code that picked -which kinds of data to fetch from the flight -computer was missing a check for TeleMini when -deciding whether to fetch the analog sensor data. -
