altos: Share common logging code. Deal with corrupt initial flight records

2017-10-28T15:42:18+00:00

Move common logging APIs from per-format files into ao_log.c. Then, change that code to check the first log record in a slot (containing the flight number) to see if it's invalid and deal with it. That involves not re-using that slot, and allowing it to be erased. Corrupted log blocks are reported with a negative flight number. Signed-off-by: Keith Packard

altos: Define AO_LOG_FORMAT in */ao_pins.h. Use in ao_cmd.c

2017-10-22T20:43:07+00:00

Instead of having a global variable define the log format, use a macro instead to save data space. Signed-off-by: Keith Packard

altos: Remove cross-block storage I/O on cc1111

2017-10-22T20:39:25+00:00

We don't ever need to be able to do storage read/write across chunks of flash on the old cc1111 products, so remove the loops that support it to save space. Signed-off-by: Keith Packard

altos: Add MPU9250 support to self test and data

The remaining hooks to make the MPU9250 work in flight. Signed-off-by: Keith Packard

altos: Stop storing pyro fired status in config block

2017-10-09T01:53:52+00:00

We already have the fired status saved in the ao_pyro_fired variable, so just use that to detect whether a channel has already been fired. Fixes possible cases where the pyro config data gets written back to eeprom with the fired bit set, which then inhibits the channel during flight. Signed-off-by: Keith Packard

altos: Allow pyro config name to end with newline, not just space/tab

2017-10-02T23:57:15+00:00

A pyro config like 'Descending' has no value associated. When it is at the end of the line, allow a newline to terminate the name instead of just a space. Signed-off-by: Keith Packard

altos: Fix debug printf in ao_pyro for state >=

altos: Don't compute filtered average of height error when HAS_ACCEL

2017-08-28T07:22:43+00:00

We only use this for baro-only devices to avoid firing drogue charges at mach transitions; we trust the combination of accel+baro to do the right thing when available. Signed-off-by: Keith Packard

altos: Don't eliminate baro above mach speed, just trust it less

2017-08-28T00:40:40+00:00

Instead of completely eliminating the baro sensor above mach speed, just derate it a bit so that the accel will dominate for speed computation and keep the device from false-triggering across mach transitions. When we completely ignored the baro sensor above mach, and the flight spent considerable time in that speed range, then the estimated height could be far from the real value. When the estimated speed dropped back down and the baro values were brought back into the computation, then the resulting rapid shift in estimated speed could trigger accidental apogee detection. By mixing in a bit of baro data even above mach, we keep the estimated height closer to the baro value and prevent this error, at least in flights measured so far. The flight known to have this problem is: 2015-09-26-serial-2093-flight-0012.eeprom Signed-off-by: Keith Packard

altos: Eliminate separate height error filter for accelerometer devices

2017-08-28T00:40:40+00:00

We don't use the error value in flight for those models anyways; it's only useful on baro-only hardware. Signed-off-by: Keith Packard
