Gyro LPF:
Digital low pass filter applied to the raw gyro data. Can help to avoid vibrations and/or reach higher PID values.

Imu2 FeedForward LPF:
Digital low pass filter applied to the attitude data before it enters the feedforward channel in the PID controller. Effective only when Imu2 Configuration is not “off”.

Low Voltage Limit:
Voltage level at which the lipo-saver function is triggered, see Advanced Functions: Lipo Saver.

Voltage Correction:
Attempts to compensate the effects of a (slowly) varying battery voltage on the PID controller tuning, see Advanced Functions: Voltage Correction.

[Use simplified PID tuning]:
Toggles between the standard PID tuning, in which the P, I D values are adjusted, and a simplified mechanism, in which tuning is achieved by only two parameters, called Damping and Stability.

[Auto write PID changes]:
When checked, any change to the PID values (and only to the PID values) is written to the STorM32 board after ca. 1 sec.

Scripts Tab

The parameters in the [GUI:Scripts] tab are comprehensively described in the article STorM32 Scripts.

Setup Tab

Imu2 Configuration:
Selects how a 2nd IMU is used. See also Using a 2nd IMU.

Virtual Channel Configuration:
Selects the physical source for the “Virtual-1”, ..., “Virtual-16” input values. See Inputs and Functions for understanding the STorM32's concept of inputs, and Configure the RC Input: Wiring for SUM-PPM Signals and Configure the RC Input: Wiring for Digital Signals for typical use cases.

Pwm Out Configuration:
Enables the pwm out function, see Advanced Functions: Pwm Out.

Pitch Motor Usage, Roll Motor Usage, Yaw Motor Usage:
Selects the operation mode of the pitch, roll, or yaw motor, respectively. When “disabled” is selected, the motor does not receive any power.

Startup Mode:
Selects the startup algorithm, can be set to “fast” for invoking fast leveling.

Imu AHRS:
Adjusts how strongly the accelerometer data is included in the data fusing for the attitude estimation. The shorter the time the stronger the accelerometer data is weighted (0 = accelerometer only, 20 = gyro only).

NT Logging:
Adjusts which parameters are logged, see NT Data Logging: GUI Settings.

Rc Pitch Offset, Rc Roll Offset, Rc Yaw Offset:
Adds a permanent offset to the camera orientation.

Beep with Motors:
Enables the emission of beeps by the motors, see Advanced Functions: Beeps.

AHRS

The following parameters affect the AHRS, and should be set with understanding.

Acc Compensation Method:
Sets the algorithm which is used for fusing the accelerometer and gyro data. Can be “standard” or “advanced”.

Imu Acc Threshold:
Maximal residual acceleration up to which the accelerometer data are taken into account in the attitude estimation. This parameter is effective only when Acc Compensation Method is set to “standard”.

The next five parameters are effective only when Acc Compensation Method is set to “advanced”. See also [1].
