altos: Switch telemetrum over to kalman filter

2011-03-21T20:42:51+00:00

This changes the full telemetry stream to include kalman data instead of the old ad-hoc flight data. It's compatible in that the packet sizes are the same so teledongle can receive either and figure out which it has received. A few plotting and testing tools are added to make validating the new code easier. Signed-off-by: Keith Packard

altos: New telemetry report format (version 4). Supports tiny telemetry.

2011-03-20T06:55:11+00:00

This completely replaces the version 3 format with a much simpler and easier to parse scheme. It's described in detail in ao_telem.h, but the basic idea is that the whole line is split into name/value pairs, separated by whitespace. Every name is unique, and the values are either strings or integers. No extraneous formatting or units are provided. Signed-off-by: Keith Packard

src/ao_cmd: Shave off bytes from doc strings

2011-03-07T08:01:46+00:00

Switch to using { func, "X args\0Desc" } to specify command, saving a char field by looking at help[0] instead, and reduce help length by doing alignment with printf instead of hardcoded spaces.

altos: TELEMETRY PROTOCOL CHANGE. Switch to 16-bit serial numbers.

2011-01-16T22:32:47+00:00

What a terrible mistake! The flight computer serial numbers were recorded in only 8 bits, so serial numbers > 255 would get truncated. There's really no fix other than bumping the field to 16 bits and reflashing every TM and TD on the planet. Very unfortunate. Signed-off-by: Keith Packard

altos: clean up radio abort paths. Share radio code.

2010-12-23T04:39:40+00:00

Instead of aborting the DMA and radio operation and expecting that to be handled reasonably by the radio receiving task, rewrite things so that the abort function just wakes the receiving task while that terminates the DMA and cleans up the radio. This eliminates all kinds of nasty bugs dealing with radio abort smashing the radio registers at the wrong time, or interrupting a radio transmission. Signed-off-by: Keith Packard

Telemetry code was mis-computing RSSI

2010-07-15T02:10:04+00:00

The RSSI data from the hardware reports in 1/2 dBm increments, and so must be divided to report plain RSSI numbers. Signed-off-by: Keith Packard

Don't abort the radio when enabling telemetry monitoring

2010-04-05T02:54:46+00:00

If telemetry monitoring is already on, then there isn't any point, and if it's not on, then presumably there isn't any radio work to abort. Signed-off-by: Keith Packard

Add flight number to telemetry stream.

2009-11-15T23:59:01+00:00

This makes it easier to tie the telemetry and eeprom files together as they're now both labeled with serial and flight numbers, which should be unique. Signed-off-by: Keith Packard

Pass accel calibration over telemetry stream. Telemetry data format change.

2009-11-03T08:40:38+00:00

This allows the ground station to convert the accelerometer sensor values into acceleration and speed data. This requires a new telemetry data structure, and so TeleMetrum and TeleDongle units must be updated synchronously. ao-view will parse either telemetry stream, and the serial format from TeleDongle now has a version number to allow for future changes.

Remove reason from ao_dma_abort
