Project ACE — Adaptive Control Engine

ACE is a powerful, ultra-responsive ground control system built specifically for the Raspberry Pi 4.

It delivers extremely fast and precise control for RC planes, drones, helicopters, and cars using ExpressLRS or Crossfire radios.

What Makes ACE Special

• Lightning-Fast Response
  Runs at 1000 times per second (1000 Hz) with almost zero delay — giving you the smoothest and most precise stick feel possible.

• Super Fast Radio Link
  Uses a custom high-speed 420,000 baud connection to your ExpressLRS or Crossfire module for the lowest possible latency.

• Smart Mixing Engine
  Advanced mixing system that handles even complex aircraft and control surfaces with ease.

• Beautiful & Easy-to-Use Interface
  Clean, modern touchscreen-friendly display with multiple color themes (Cyan, Red, Green, Amber) that you can change on the fly.

• Full Support for Multiple Vehicles
  Dedicated screens and tuning pages for:

  • Airplanes
  • (soon)Drones / Multirotors
  • (soon)Helicopters
  • (soon)Cars

  Each vehicle gets its own dashboard, easy 5-page tuning wizards, and custom RC mapping.

• Highly Tunable Controls
  Full adjustment for deadzone, expo, rates, endpoints, and more — all with real-time feedback.

• Rock-Solid Performance
  Designed from the ground up to run smoothly with minimal jitter, even under heavy load.

Hardware You Need

• Raspberry Pi 4 or Compute Module 4
• ExpressLRS or Crossfire radio module connected to GPIO 12 & 13
• Touchscreen or HDMI monitor

How to Install & Run

1. Open a terminal on your Raspberry Pi
2. Run these commands:

mkdir build && cd build
cmake ..
make -j4

export DISPLAY=:0
export QT_QPA_PLATFORM=xcb
