Adds a new angle limiting mode for pilots who are learning to fly in acro mode. Primarily targeted at new LOS acro pilots, but can be used with FPV as well.
The feature is activated with a new mode named "ACRO TRAINER". When the feature is active, the craft will fly in normal acro mode but will limit roll/pitch axes so that they don't exceed the configured angle limit. New pilots can start with a small angle limit and progressively increase as their skills improve.
The accelerometer must be enabled for the feature to be configured and function.
Also the feature will only be active while in acro flight and will disable if ANGLE or HORIZON modes are selected.
For most users all they need to do is simply configure the new mode to be active as desired on the "Modes" tab in the configurator and configure the desired angle limit in the cli.
Configuration parameters:
acro_trainer_angle_limit: (range 10-80) Angle limit in degrees.
acro_trainer_lookahead_ms: (range 10-200) Time in milliseconds that the logic will "look ahead" to help minimize overshoot and bounce-back if the limit is approached at high gyro rates. The default value of 50 should be good for most users. For low powered or unresponsive craft (micros or brushed) it may be helpful to increase this setting if you're seeing substantial overshoot.
acro_trainer_debug_axis: (ROLL, PITCH) The axis that will log information if debugging is active.
To enable debugging:
set debug_mode = ACRO_TRAINER
debug(0) - Current angle
debug(1) - The internal logic state
debug(2) - Modified setpoint
debug(3) - Projected angle based gyro rate and lookahead period
* CF/BF - Set STM32F7 SPI FAST clock to 13.5Mhz - Gyros not stable at
27mhz.
* CF/BF - Initial SPRacingF7DUAL commit.
Support two simultaneous gyro support (code by Dominic Clifton and Martin Budden)
There are new debug modes so you can see the difference between each gyro.
Notes:
* spi bus instance caching broke spi mpu detection because the detection
tries I2C first which overwrites the selected bus instance when using
dual gyro.
* ALL other dual-gyro boards have one sensor per bus. SPRacingF7DUAL is has two per bus and thus commit has a lot of changes to fix SPI/BUS/GYRO initialisation issues.
* CF/BF - Add SPRacingF4EVODG target.
This target adds a second gyro to the board using the SPI pads on the back of the board.
* CF/BF - Temporarily disable Gyro EXTI pin to allow NEO target to build.
Detects runaway pidSum values on takeoff and auto-disarms to prevent the "Tasmanian Devil" caused by incorrect props, wrong motor order/direction, incorrect flight controller orientation, etc. After a successful takeoff and normal flight is detected the feature is disabled for the remainder of the battery.
