altos: Force telemetry rate to 38400 when ao_force_freq is set

2018-10-05T06:10:59+00:00

ao_force_freq is used by TeleMini to set the radio to known values. As TeleMini v3.0 also has configurable telemetry rates, this value also needs to be set back to a known value. Signed-off-by: Keith Packard

altos: Switch global 'log' to 'ao_log_data'

2018-08-15T22:43:28+00:00

Avoid conflicts with 'log' math function. Signed-off-by: Keith Packard

altos: Remove spurious 'const' from ao_state_names

2018-08-15T22:40:15+00:00

Current gcc complains about this. Signed-off-by: Keith Packard

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
