7 Version 1.1.1 is a bug-fix release. It fixes a couple of bugs in
8 AltosUI and one firmware bug that affects TeleMetrum version 1.0
9 boards. Thanks to Bob Brown for help diagnosing the Google Earth
10 file export issue, and for suggesting the addition of the Ground
11 Distance value in the Descent tab.
14 AltOS Firmware Changes
18 TeleMetrum v1.0 boards use the AT45DB081D flash memory part to
19 store flight data, which is different from later TeleMetrum
20 boards. The AltOS v1.1 driver for this chip couldn't erase
21 memory, leaving it impossible to delete flight data or update
22 configuration values. This bug doesn't affect newer TeleMetrum
23 boards, and it doesn't affect the safety of rockets flying
34 Creating a Google Earth file (KML) from on-board flight data
35 (EEPROM) would generate an empty file. The code responsible
36 for reading the EEPROM file wasn't ever setting the GPS valid
37 bits, and so the KML export code thought there was no GPS data
43 The “Landed” tab was displaying all values in metric units,
44 even when AltosUI was configured to display imperial
45 units. Somehow I just missed this tab when doing the units stuff.
50 The “Descent” tab displays the range to the rocket, which is a
51 combination of the over-the-ground distance to the rockets
52 current latitude/longitude and the height of the rocket. As
53 such, it's useful for knowing how far away the rocket is, but
54 difficult to use when estimating where the rocket might
55 eventually land. A new “Ground Distance” field has been added
56 which displays the distance to a spot right underneath the
62 Sensor data wasn't being displayed for TeleMini flight
63 computers in Monitor Idle mode, including things like battery
64 voltage. The code that picked which kinds of data to fetch
65 from the flight computer was missing a check for TeleMini when
66 deciding whether to fetch the analog sensor data.
