Version 1.1 is a minor release. It provides a few new features -in AltosUI and the AltOS firmware and fixes bugs.

1. AltOS

AltOS Firmware New Features:

-Add apogee-lockout value. Overrides the apogee -detection logic to prevent incorrect apogee charge -firing. -
-Force the radio frequency to 434.550MHz when the -debug clock pin is connected to ground at boot -time. This provides a way to talk to a TeleMini -which is configured to some unknown frequency. -
-Provide RSSI values for Monitor Idle mode. This -makes it easy to check radio range without needing -to go to flight mode. -

AltOS Fixes:

-Fix a bug where the data reported in telemetry -packets was from 320ms ago. -
-Fix a bug which caused the old received telemetry -packets to be retransmitted over the USB link when -the radio was turned off and back on. -

AltosUI New Features:

-Make the look-n-feel configurable, providing a choice from -the available options. -
-Add an Age element to mark how long since a -telemetry packet has been received. Useful to -quickly gauge whether communications with the rocket -are still active. -
-Add Configure Ground Station dialog to set the -radio frequency used by a particular TeleDongle -without having to go through the flight monitor UI. -
-Add configuration for the new apogee-lockout -value. A menu provides a list of reasonable values, -or the value can be set by hand. -
-Add Imperial units mode to present data in feet -instead of meters. -

AltosUI Fixes:

-Fix a bug that caused GPS ready to happen too -quickly. The software was using every telemetry -packet to signal new GPS data, which caused GPS -ready to be signalled after 10 packets instead of 10 -GPS updates. -
-Fix Google Earth data export to work with recent -versions. The google earth file loading code got a -lot pickier, requiring some minor white space -changes in the export code. -
-Changed how flight data are downloaded. Now there’s -an initial dialog asking which flights to download, -and after that finishes, a second dialog comes up -asking which flights to delete. -
-Re-compute time spent in each state for the flight -graph; this figures out the actual boost and landing -times instead of using the conservative values -provide by the flight electronics. This improves the -accuracy of the boost acceleration and main descent -rate computations. -
-Make AltosUI run on Mac OS Lion. The default Java -heap space was dramatically reduced for this release -causing much of the UI to fail randomly. This most -often affected the satellite mapping download and -displays. -
-Change how data are displayed in the table tab of -the flight monitoring window. This eliminates -entries duplicated from the header and adds both -current altitude and pad altitude, which are useful -in Monitor Idle mode. -
