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

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

21 Creating a Google Earth file (KML) from on-board flight data
22 (EEPROM) would generate an empty file. The code responsible
23 for reading the EEPROM file wasn't ever setting the GPS valid
24 bits, and so the KML export code thought there was no GPS data

27 The “Landed” tab was displaying all values in metric units,
28 even when AltosUI was configured to display imperial
29 units. Somehow I just missed this tab when doing the units stuff.

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

40 Sensor data wasn't being displayed for TeleMini flight
41 computers in Monitor Idle mode, including things like battery
42 voltage. The code that picked which kinds of data to fetch
43 from the flight computer was missing a check for TeleMini when
44 deciding whether to fetch the analog sensor data.
