Release Notes

E.3. Release Notes for Version 1.6

Version 1.6 includes support for our updated TeleDongle v3.0 product and bug fixes in in the flight

software for all our boards and ground station interfaces.

E.3.1. AltOS

AltOS New Features

• Add support for TeleDongle v3.0 boards.

AltOS Fixes

• Don’t beep out the continuity twice by accident in idle mode. If the battery voltage report takes longer

than the initialiation sequence, the igniter continuity would get reported twice.

• Record all 32 bits of gyro calibration data in TeleMega and EasyMega log files. This fixes computation

of the gyro rates in AltosUI.

• Change TeleDongle LED usage. Green LED flashes when valid packet is received. Red LED flashes

when invalid packet is received.

• Replace LPC11U14 SPI driver with non-interrupt version. The interrupt code would occasionally

wedge on long transfers if interrupts were blocked for too long. This affects all released TeleGPS

products; if you have a TeleGPS device, you’ll want to reflash the firmware.

E.3.2. AltosUI and TeleGPS Applications

AltosUI and TeleGPS New Features

• Compute tilt angle from TeleMega and EasyMega log files. This duplicates the quaternion-based angle

tracking code from the flight firmware inside the ground station software so that post-flight analysis

can include evaluation of the tilt angle.

• Shows the tool button window when starting with a data file specified. This means that opening

a data file from the file manager will now bring up the main window to let you operate the whole

application.

AltosUI Fixes

• Show the

Connecting

dialog when using Monitor Idle. Lets you cancel the Monitor Idle startup when

connecting over the radio link.

• Make

Monitor Idle

work for TeleGPS devices when connected over USB. It’s nice for testing without

needing to broadcast over the radio.

• Use different Windows API to discover USB devices. This works better on my Windows 7 box, and will

be used if the older API fails to provide the necessary information.

• Look in more places in the registry to try and identify the installed Java version on Windows. If you

install the default 32-bit version of Windows on a 64-bit OS, the Java registry information is hiding

\SOFTWARE\Wow6432Node for some reason.
