mjb/altos, branch 0.9.4.5

simplify version in last changelog entry so git-dch is less confused

2011-08-08T13:33:09+00:00

update version for a Bdale build for use turning on TeleMini v1.0

2011-08-08T13:30:42+00:00

altos/altosui: Add pad orientation configure option

2011-08-03T02:07:56+00:00

Allow TeleMetrum to be operated with the antenna pointing downwards on the pad. This provides some additional flexibility when designing an ebay. The accelerometer calibration levels are flipped around to match, so no re-calibration should be required. Signed-off-by: Keith Packard

altosui: Add idle monitor dialog

2011-08-03T01:03:37+00:00

This monitors a telemetrum device in idle mode, either directly or through a teledongle, allowing the GPS status and batteries to be monitored without resorting to placing the device in pad mode. Signed-off-by: Keith Packard

altosui: Simple timeouts don't work with query data

2011-08-03T01:03:37+00:00

To get the query to come back, it's best to abort and retry the command, other wise the command may have been lost to the previous connection. Signed-off-by: Keith Packard

altosui: Parse accel cal from 'c s' command

2011-08-03T00:41:02+00:00

These fields weren't used before, so the code to parse them hadn't been written. Signed-off-by: Keith Packard

altosui: Standard text field in flight UI needs more width (now 20)

2011-08-03T00:40:02+00:00

Latitude and longitude take more than 16 characters. Signed-off-by: Keith Packard

altos: Require sequencing through 'main' state before landing

2011-08-02T09:09:23+00:00

The old version of the code would permit the flight to go straight from 'drogue' to 'landed' without passing through 'main' at all. This meant that a false landing detection would leave the main charge unfired, potentially causing the airframe to land on drogue alone. Requiring that the flight sequence pass through main ensures that the main charge will get fired at the right time, although if the airframe lands higher than that altitude, it will not go to 'landed' mode ever.

altos: Reduce height averaging filter time constant

2011-08-02T08:53:33+00:00

Using the longer time constant could lead to false landing detection just after apogee, which is definitely not a good idea. Signed-off-by: Keith Packard

altos: Average height values for landing detection

2011-08-02T07:30:08+00:00

Instead of using the direct output of the kalman filter and hoping that is quiet enough to detect landing, filter that with a long exponential decay filter and then check to make sure that doesn't change more than 2m in 5 seconds as a trigger for landing detection. Tested with existing telemetrum flight logs and it correctly detects landing in all cases. Signed-off-by: Keith Packard
