= Release Notes for Version 1.1
:toc!:
:doctype: article
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.
== 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.
== 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.
