altos: Add separate 'ao_launch_tick'. Use in pyro and lockout.

2018-08-05T03:13:42+00:00

Prior to this, there was only ao_boost_tick, which got reset at each motor burn start. That meant there wasn't any way to measure total flight time for pyro channels and 'apogee lockout' was based on time since most recent motor start instead of total flight time. Now pyro channels and apogee lockout both use total flight time, while motor burn length still uses time since most recent motor burn start (as it should). Docs and UI updated to use 'launch' instead of 'boost' to try and make the change clear. Signed-off-by: Keith Packard

altos: Change 'after motor' pyro check to be >= instead of ==

2018-08-05T01:04:19+00:00

This makes after motor stay valid even if further motors burn. Signed-off-by: Keith Packard

altos/test: Compute and show height error tracker in ao_flight_test

2018-07-02T21:25:10+00:00

Enable the computation of ao_error_h_sq_avg in ao_flight_test even when an accelerometer is present to allow review of that data. Signed-off-by: Keith Packard

altos: Eliminate height requirement for coast detect

2018-05-07T16:21:56+00:00

We had required a minimum altitude of 100m to transition from boost to coast. With small motors in a heavy multi-staged rocket, this can fail to detect coast in time to light the second motor. Also, this would fail to deploy recovery systems if the flight failed before reaching 100m. Signed-off-by: Keith Packard

altos/chaoskey-v1.0: Add endpoint for reading flash contents

2018-05-07T16:21:56+00:00

This creates another IN endpoint which provides the contents of flash for validation of the firmware load on the host. Signed-off-by: Keith Packard

altos/kernel: Add USB descriptors for IN3

2018-05-07T16:22:01+00:00

This adds the necessary descriptor information to support another IN endpoint for applications. Signed-off-by: Keith Packard

altos/kernel: Define usb IN2/IN3 functions

2018-05-07T16:21:56+00:00

These are putchar and flush functions that are used when sending data to the additional IN2 and IN3 endpoints. Signed-off-by: Keith Packard

altos: Use max of 64 previous orient values when checking pyro limits

2018-04-27T02:24:21+00:00

Instead of checking just a single measurement to see if the orientation is outside of the desired limits, use the maximum of 64 previous values to that rapidly changing orientation won't accidentally enable a pyro channel if sampled at the 'wrong time'. Signed-off-by: Keith Packard

altos: Make panic beeps use fixed frequencies

2018-03-16T21:53:14+00:00

This ensures that the beeps will work even before the configuration has been loaded. Signed-off-by: Keith Packard

altos/kernel: Use ao_put_string for syntax error message

2018-01-07T19:47:57+00:00

Avoid using puts, which can be a large library function. Signed-off-by: Keith Packard
