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

- AltOS Firmware Changes -

- Add apogee-lockout value. Overrides the apogee detection logic to - prevent incorrect apogee charge firing. -
- Fix a bug where the data reported in telemetry packets was - from 320ms ago. -
- 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. -
- 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 Changes -

- 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. -
- 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. -
- 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. -
- Add Imperial units mode to present data in feet instead of - meters. -

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:

+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. +
