Welcome to the RC Info Center (RCIC) Wiki

RC Info Center (RCIC) v4.0 is a highly optimized, full-featured telemetry suite designed specifically for EdgeTX 2.9+ transmitters. It transforms your radio's screen into a powerful, modular, and interactive flight dashboard.

With version 4.0, RCIC evolves from a simple script into a dual-module architecture: a lightweight background telemetry dashboard and a dedicated, full-screen configuration tool.

Design Philosophy

RCIC is built from the ground up to respect the constrained hardware (STM32 processors and limited RAM) found in modern radios. To ensure zero lag and maintain a high refresh rate, the script utilizes:

• Zero-RAM Overhead QR Generation: The local QR Code generator relies entirely on pure math and native Lua 5.3 static bitmasks. It draws pixels directly to the screen buffer without invoking heavy table allocations.
• Aggressive Garbage Collection Avoidance: Variables, pre-formatted strings, and absolute screen coordinates are cached in memory during initialization to eliminate dynamic memory fragmentation during flight.
• Instant-Save Configuration: Settings are handled by an independent script and saved to a lightweight CSV file, allowing real-time tweaks without restarting the telemetry engine.

Core Capabilities

• 7-Tab Modular Interface: Switch smoothly between Battery (BAT), Navigation (GPS), Tactical Radar (RAD), Link Quality (LNK), Power & Efficiency (PWR), Locator (LOC), and Statistics (TOT).
• Customizable Layout: Disable any tab you don't need. The interface dynamically resizes and centers the remaining tabs to maximize screen real estate.
• Blackbox GPX Logging: Automatically records your flight path (coordinates, altitude, and time) into standard .gpx files on your SD card whenever the drone is armed and has a valid 3D fix.
• Intelligent Battery Management: Features real-time cell detection, Anti-Sag filtering to suppress false alarms during throttle punch-outs, and dynamic flight time estimation.
• Multi-Protocol Link Quality: Adaptive UI that displays advanced RF metrics (RQly, TQly, SNR, RFMD, dual antenna RSSI) for ELRS/Crossfire, or standard metrics for traditional protocols.
• Offline Recovery Tools: Built-in Open Location Code (Plus Codes) and geo: URI QR Code generation to find your model using your smartphone, with absolutely no internet connection required on the controller.
• Drone Locator: An acoustic and visual RSSI tracker (Geiger-counter style) that guides you to a downed quadcopter in thick brush.
• Touch-Screen Support: Native touch navigation for radios equipped with touch panels (e.g., Radiomaster TX16S).
