FC Configuration - ADOS Documentation

The Configure section provides more than 60 panels for setting up your flight controller. Each panel reads parameters from the FC, lets you edit them, and writes changes back. The panels adapt automatically based on the detected firmware (ArduPilot, PX4, Betaflight, or iNav).

How Configuration Works

Every panel follows the same workflow:

Read from FC: Click “Read” to fetch parameters from the flight controller.
Edit values: Change parameters in the UI. Modified values are highlighted.
Save to RAM: Click “Save” to write changes to the FC’s working memory.
Write to Flash: Click “Write to Flash” to persist changes across reboots. (ArduPilot auto-saves to EEPROM on each parameter write, so this is a belt-and-suspenders step.)

Parameters cannot be written while the vehicle is armed. The armed-lock overlay blocks all writes as a safety measure. Disarm first, then configure.

Panel Categories

Flight

Panel	Description
Flight Modes	Map RC switch positions to flight modes. ArduPilot supports 6 mode slots. PX4 supports 6 main modes plus sub-modes.
Frame	Select the airframe type (quad, hexa, octa, Y6, etc.) and motor layout.
Airframe (PX4)	PX4-specific airframe selection with model presets.
Actuator (PX4)	PX4 actuator configuration and testing.
Outputs	Map motors and servos to physical outputs. Timer group diagram shows which outputs share PWM timers.
Receiver	RC receiver protocol, channel mapping, and failsafe values.

Safety

Panel	Description
Failsafe	Configure battery, GCS, RC, and geofence failsafe actions and thresholds.
Geofence	FC-level geofence parameters (max altitude, max distance, breach action). See also the Geofence Editor.
Pre-Arm Checks	View and configure which pre-arm checks the FC enforces before allowing arming.

Sensors

Panel	Description
Sensors	Configure rangefinder, optical flow, airspeed sensor, and barometer settings. Each sensor type is in a collapsible section.
GPS	GPS module configuration, constellation selection, and GNSS settings.
Sensor Graph	Live plots of sensor data for debugging (accel, gyro, mag, baro).

Tuning

Panel	Description
PID Tuning	Adjust roll, pitch, and yaw PID gains. Autotune trigger. Preset profiles. Filter settings. Live PID response graph for tuning analysis.
Rate Profile (Betaflight)	Betaflight rate curve configuration with visual curve preview.
Adjustments (Betaflight)	In-flight adjustment mappings (RC channel to PID adjustments).

Display

Panel	Description
OSD Editor	Drag-and-drop OSD element placement across 4 independent screens. 25+ configurable elements. Preset layouts.
OSD Editor (Betaflight)	Betaflight-specific OSD configuration with BF element set.
LED	Configure LED strip patterns. 11 LED types, brightness, color picker, and pattern preview animation.

Communications

Panel	Description
Serial Ports	Configure serial port protocols, baud rates, and options. 8 ports, 25+ protocols, 14 baud rates.
Telemetry Radio	SiK radio configuration (air speed, ECC, MAVLink version, TX power).
MAVLink Inspector	Live view of incoming and outgoing MAVLink messages with decode.
MAVLink Shell (PX4)	PX4 NuttShell console over MAVLink. Type commands directly to the FC.
CLI (Betaflight)	Betaflight command-line interface over MSP.
Blackbox (Betaflight)	Betaflight blackbox data log configuration and download.
CAN Monitor	DroneCAN/UAVCAN bus monitoring. View CAN node info and messages.

Power

Panel	Description
Power	Battery monitor configuration for BATT1 and BATT2. Voltage divider, amps per volt, cell count, and capacity. Live cell voltage display.

Peripherals

Panel	Description
Gimbal	Mount type, axis limits, manual control sliders, ROI targeting. Supports Gimbal Manager v2 protocol.
Camera	Camera trigger configuration (servo, relay, distance-based). Survey helper calculator for trigger intervals.
VTX (Betaflight)	Video transmitter settings (band, channel, power, pit mode).
Betaflight Config (Betaflight)	Betaflight system configuration (features, board alignment, name).
Aux Modes (Betaflight)	Map RC aux channels to Betaflight modes (arm, angle, horizon, beeper, etc.).
Motors (Betaflight)	Motor testing and direction configuration for Betaflight.

Debug

Panel	Description
Debug	Real-time data graphing with table view, CSV export. 4-chart limit. 300-sample ring buffer per chart. Useful for debugging sensor issues or tuning.

Firmware

Panel	Description
Firmware	Flash firmware, view board info, backup and restore parameters. See Firmware Flashing.

Parameters

Panel	Description
Parameters	Full parameter tree browser with search, edit, modified filter, and import/export. See Parameters.

Calibration

Panel	Description
Calibration	9 sensor calibration wizards. See Calibration.

Firmware-Specific Panels

Some panels only appear for certain firmware:

Panel	ArduPilot	PX4	Betaflight
Airframe	No	Yes	No
Actuator	No	Yes	No
MAVLink Shell	No	Yes	No
Aux Modes	No	No	Yes
Rate Profile	No	No	Yes
BF Config	No	No	Yes
BF Motors	No	No	Yes
BF OSD	No	No	Yes
CLI	No	No	Yes
VTX	No	No	Yes
Blackbox	No	No	Yes
Adjustments	No	No	Yes

The FC configuration navigation filters panels by the requiredCapability field. Only panels compatible with the connected firmware appear.

Safety Features

Armed lock: All parameter writes are blocked while the vehicle is armed
Unsaved changes guard: Navigating away from a panel with dirty (unsaved) parameters triggers a warning
Parameter validation: Values are checked against min/max ranges before writing
Reboot banner: Panels that require a reboot after changes show a persistent banner
