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
17 TeleMetrum v1.0 boards use the AT45DB081D flash memory part to
18 store flight data, which is different from later TeleMetrum
19 boards. The AltOS v1.1 driver for this chip couldn't erase
20 memory, leaving it impossible to delete flight data or update
21 configuration values. This bug doesn't affect newer TeleMetrum
22 boards, and it doesn't affect the safety of rockets flying
31 Creating a Google Earth file (KML) from on-board flight data
32 (EEPROM) would generate an empty file. The code responsible
33 for reading the EEPROM file wasn't ever setting the GPS valid
34 bits, and so the KML export code thought there was no GPS data
38 The “Landed” tab was displaying all values in metric units,
39 even when AltosUI was configured to display imperial
40 units. Somehow I just missed this tab when doing the units stuff.
43 The “Descent” tab displays the range to the rocket, which is a
44 combination of the over-the-ground distance to the rockets
45 current latitude/longitude and the height of the rocket. As
46 such, it's useful for knowing how far away the rocket is, but
47 difficult to use when estimating where the rocket might
48 eventually land. A new “Ground Distance” field has been added
49 which displays the distance to a spot right underneath the
53 Sensor data wasn't being displayed for TeleMini flight
54 computers in Monitor Idle mode, including things like battery
55 voltage. The code that picked which kinds of data to fetch
56 from the flight computer was missing a check for TeleMini when
57 deciding whether to fetch the analog sensor data.
