altos: Restructure altos build to prepare for multi-arch support

2011-08-26T03:49:11+00:00

Split out sources into separate directories: core: architecture and product independent bits cc1111: cc1111-specific code drivers: architecture independent drivers product: product-specific sources and Makefile fragments util: scripts for building stuff This should have no effect on the built products, but testing is encouraged Signed-off-by: Keith Packard

altos: Switch ao_log.c and ao_log_big.c xdata to pdata

altos: Split up flight code into separate flight/sample/kalman bits

2011-03-29T00:54:44+00:00

The flight code mashed together data processing, filtering and actual flight managament into one giant pile. Split things up so that we have: ao_sample.c: Sensor data processing. Reads the ring, handles calibration ao_kalman.c: Filter the data to track the accel/speed/height values ao_flight.c: Flight state management, specific to rocketry. The plan is to re-use ao_sample.c and ao_kalman.c for hardware not specifically designed for rocketry, like TeleNano. Signed-off-by: Keith Packard

altos: full logging must flush pending data before checking state

2011-03-27T06:38:54+00:00

Flight state must be checked only after any pending data have been written to the log as the 'current' flight state is only valid when the pending data values have been processed. This ensures that the 'boost' state is not marked until the full ring of data is written. This ensures that the data processing code can find the barometer values from before boost to get an idea of the ground pressure value. Signed-off-by: Keith Packard

altos: Variable log rate in full logging code too

2011-03-27T06:15:36+00:00

With the fixed ADC rate used to get better data during flight, the logging code now needs to vary the data storage rate so that descent data is recorded at 10 samples/second while ascent data is recorded at 1 sample per second. Having the logging code do this itself eliminates any interaction with the flight code. Signed-off-by: Keith Packard

altos: Add tiny logging for TeleMini/TeleNano

2011-03-17T23:00:10+00:00

This splits the logging code into management of the log space within storage and separate code to actually write suitable log entries. A new log writing module, ao_log_tiny, is added which writes only altimeter data at a fairly low data rate for devices using on-chip storage. Signed-off-by: Keith Packard
