Implemented automatic ranging of Alt Hold gains. Works well in simulator and testing.
- alt hold estimation moved to 50 hz
- simple fixed observer calc for smooth and accurate climb rates useful for derivative calcs
- auto-reset of the I term by moving I value into throttle value. This recalcs the gain every 20seconds for battery drainage compensation in long flights.
- remove filtering for Nav_throttle
- added a way to lower the gain on nav_throttle for descents by / climb_rate error by 2 - seems to work OK and keeps copter from dropping like a rock when the Baro drifts quickly lower.
- removed old throttle hold set point code
- made throttle override for alt hold +- 200 vs 250
* config variable CONFIG_CHANNELS has possible values
CHANNEL_CONFIG_DEFAULT or CHANNEL_CONFIG_CUSTOM
* config_channels.h only provides APM1/APM2 mapping when
CONFIG_CHANNELS == CHANNEL_CONFIG_DEFAULT
Upped Nav_P defaults to 3 based on windy flight testing
Added minimum WP speed define of 1m/s
Upped loiter_I for better wind performance - was not seeing any overshoot in logs
Made Nav_I default of 0, since we are not using it in the code.
Fixes compatibility for APM2. Also a significant update to the battery monitoring code: We previously had monitoring modes for individual cell voltages for 3 and 4 cell lipos. These have been removed as they were never really supported (the cell voltages were computed but were not reported or recorded anywhere). Also, some clean-up/prep work was done for supporting monitoring 2 separate battery packs. The CLI battery and current monitoring tests were consolidated into 1 test.
