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

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

altos: Add ability to read new TELEM files to ao_flight_test

2011-07-18T01:49:55+00:00

Not that telem files are currently very useful as the kalman filter gets completly confused by the variable steps caused by missing data, but... Signed-off-by: Keith Packard

altos, altosui: Add igniter mode (dual, apogee, main)

2011-07-17T15:14:09+00:00

This provides for redundant charges for either apogee or main. Signed-off-by: Keith Packard

altos: new versions of sdcc require __ prefixes for custom keywords

2011-07-09T20:09:57+00:00

Fortunately, 2.9.1 appears to accept either, so we can switch now and prepare for sdcc 3.0.0. Signed-off-by: Keith Packard

altos: product defines are always in ao_product.h

2011-07-07T00:49:01+00:00

When all products were built in a single directory, each one had a separate version of ao_product.h. Now that they all reside in sub-directories, each directory has its own ao_product.h This change is needed so that other modules in the system can use the product defines; otherwise, ao_product.h was not built at the right time.

altos: Ensure low-rate telem packets interleave with sensor telem packets

2011-07-06T23:43:17+00:00

To avoid over-committing the radio link, we want to send only one low rate packet after each sensor packet. However, the initializations for this were incorrect, causing the configuration and location packets to be sent at the same time. Signed-off-by: Keith Packard

altos: Remove ao_telemetry_orig.c and ao_telemetry_tiny.c

2011-07-06T23:19:46+00:00

All products use the common ao_telemetry.c code now Signed-off-by: Keith Packard
