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.

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.

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).
