## ✨ Features

- **Packet Framing** — Header + Command ID + Payload + XOR Checksum
- **GimbalController** — Normalized PID output → servo angle conversion
- **Exponential Smoothing** — Prevents jittery servo movement
- **Rate Limiting** — 50Hz max update rate to prevent serial flooding
- **Heartbeat** — Keep-alive packets for connection monitoring

---

## 📦 Installation

```bash
pip install dronelink
```

---

## 🚀 Quick Start

```python
from dronelink import DroneLink, GimbalController

# Connect to flight controller
drone = DroneLink("COM3", baudrate=115200)

# Create gimbal controller
gimbal = GimbalController(drone, pan_range=(-90, 90), tilt_range=(-45, 45))

# In your tracking loop:
# pid_x, pid_y are from servopilot (-1.0 to +1.0)
gimbal.set_angles(pan=pid_x, tilt=pid_y)

# Send heartbeat periodically
drone.send_heartbeat()

# Check status
print(gimbal.get_status())

# Cleanup
drone.close()
```

### Integration with ServoPilot

```python
from servopilot import DualAxisPID
from dronelink import DroneLink, GimbalController

pid = DualAxisPID(kp=0.4, ki=0.008, kd=0.25)
drone = DroneLink("COM3")
gimbal = GimbalController(drone)

# Tracking loop
signal_x, signal_y = pid.update(error_x, error_y, dt=1/30)
gimbal.set_angles(pan=signal_x, tilt=signal_y)
```
