DJI RC Emulator

v1.1 — by deviver
Turns your DJI RC controller into a virtual Xbox 360 gamepad for FPV simulators

---

Use your DJI RC (RM330, RC-N1, RC-N2, RC231, etc.) as a virtual Xbox 360 controller in Liftoff, VelociDrone, DCL, or any PC game.

The RC connects via USB-C and the app reads sticks/buttons over the DJI DUML protocol, then emulates a gamepad via ViGEm.

---

Features

• Live stick visualization — see both sticks move in real-time
• 6-channel support — 4 sticks + camera wheel + scroll wheel
• Button mapping — C1, C2, Photo, Video, Fn, Scroll mapped to Xbox buttons
• Expo / Rates curves — adjustable per-axis
• Axis remapping — swap sticks, invert axes, Mode 1/2/3/4 presets
• Deadzones — configurable per-axis
• Auto-reconnect — handles USB disconnect/reconnect gracefully
• Low latency — direct gamepad push from RC callback, no threading overhead
• Setup wizard — first-run tutorial with dependency checks
• Persistent config — all settings saved to config.json

---

Requirements

1. Windows 10/11 (ViGEm is Windows-only)
2. Python 3.10+ — python.org/downloads
3. ViGEm Bus Driver — REQUIRED for virtual gamepad
   • Download from: github.com/nefarius/ViGEmBus/releases
   • Install ViGEmBus_Setup_x64.msi
   • Reboot after install
4. DJI RC controller connected via USB-C (bottom port)

---

Installation

# 1. Install ViGEm Bus Driver first (see link above)

# 2. Install Python dependencies
pip install -r requirements.txt

# 3. Connect your DJI RC via USB-C

# 4. Run the app
python main.py
# Or double-click start.bat

Or use setup_and_run.bat for automatic dependency installation on first run.

---

Usage

1. Connect your DJI RC to your PC via the USB-C port on the bottom of the controller
2. Launch the app — run start.bat or python main.py
3. Click "Connect" — the app will auto-detect the RC. If not found, select it from the dropdown
4. Move the sticks — you should see them move in the visualizer
5. Open your simulator (Liftoff, etc.) — configure it to use the Xbox 360 controller
6. Adjust settings — click Settings to tune expo, rates, deadzones, and button mapping

Troubleshooting

"ViGEm not available" error

• Install ViGEm Bus Driver from github.com/nefarius/ViGEmBus/releases
• Reboot after installing

RC not detected

• USB-C must be in the bottom port (not top/side)
• Check Device Manager for "DJI USB VCOM" ports
• For RM330/RC2: install WinUSB driver via Zadig when prompted

Sticks not responding

• Click "Connect" and check for green status
• Disconnect and reconnect if sticks respond slowly
