Subject: Use recorded accelerometer baseline data in ao_flight_test
X-Git-Tag: 0.2~11
X-Git-Url: https://git.gag.com/?p=fw%2Faltos;a=commitdiff_plain;h=497c89a7d08920630894b2605c3b6a0bdc4c229b

Use recorded accelerometer baseline data in ao_flight_test

With the flight computer recording a long-term average value for the
accelerometer in the flight record, use that to prime the flight test code
when running a log file through the simulator.
