altos: Program default flight log max value for new boards

2011-01-19T19:21:52+00:00

New boards have no config space values at all, and so they need each value to be set. Yes, this should be fixed so that there aren't two copies of these assignments. Signed-off-by: Keith Packard

altos: Use 5V reference data to correct accelerometer measurements.

2011-01-17T05:52:50+00:00

When the 3.3V and 5V values shift relative to each other (usually due to changes in power consumption), the measured acceleration will appear to shift. This patch converts the 3.3V referenced acceleration value into a 5V referenced acceleration, eliminating this error. Signed-off-by: Keith Packard

altos: Optimize fetching of ADC data in flight code

2011-01-17T04:24:36+00:00

This stores the address of the desired sample in a local variable and then fetches through that. Saves quite a few instructions. Signed-off-by: Keith Packard

altos: Sample the accelerometer reference voltage on v1.1 boards

2011-01-17T04:24:36+00:00

This places the 5v reference samples in an array parallel to the basic ADC values. It doesn't do anything with the values, just stores them. Signed-off-by: Keith Packard

altos: Ensure flight code gets first crack at new ADC data

2011-01-17T04:24:34+00:00

Instead of having everyone wait on the raw ADC ring, have the flight code wait on that and have everyone else wait for the flight code to finish looking at the data and move its pointer forwards. Signed-off-by: Keith Packard

altos: Auto-calibrate linux-based flight testing code

2011-01-17T04:24:13+00:00

Use the provided ground acceleration average to set the two accelerometer calibration values so that the flight code will detect pad/idle mode correctly. Signed-off-by: Keith Packard

Rework invalid accel cal detection code

2011-01-17T02:03:40+00:00

Slightly reduces code space. Uncalibrated accelerometer now enters invalid state as well. Signed-off-by: Mike Beattie

altos: Add DATA_TO_XDATA to linux test harness

2011-01-16T22:35:29+00:00

The flight test harness needs to expose every function used by the flight code in some form, and this macro is about to become used. Signed-off-by: Keith Packard

altos: Added check for out of bounds accel

2011-01-16T22:35:29+00:00

Chose invalid flight mode instead of idle to give user feedback. Signed-off-by: Mike Beattie

altos: Added check for an accel value above 1.5g

2011-01-16T22:35:29+00:00

When detecting flight or idle mode, this should indicate that accel cal values are out of whack. Signed-off-by: Mike Beattie
