## 🌐 Web Control Interface
|
||||||
|
|
||||||
|
The DShotRMT library now includes a modern web interface for wireless motor control:
|
||||||
|
|
||||||
|
### Features
|
||||||
|
- **Responsive Design:** Works on mobile phones, tablets, and desktop computers
|
||||||
|
- **WiFi Access Point:** Creates hotspot "DShotRMT Control" (Password: 12345678)
|
||||||
|
- **Safety System:** Arming/disarming switch prevents accidental motor activation
|
||||||
|
- **Real-time Control:** Instant throttle response via WebSocket communication
|
||||||
|
- **Live Telemetry:** Real-time RPM display (bidirectional mode only)
|
||||||
|
- **Auto-reconnect:** Automatically reconnects on connection loss
|
||||||
|
|
||||||
|
### Web Interface Access
|
||||||
|
1. Connect to WiFi network: **"DShotRMT Control"**
|
||||||
|
2. Password: **12345678**
|
||||||
|
3. Open browser and navigate to: **http://10.10.10.1**
|
||||||
|
|
||||||
|
### Safety Features
|
||||||
|
- Motor control is **disabled by default** (disarmed state)
|
||||||
|
- Toggle the **ARMING SWITCH** to enable motor control
|
||||||
|
- Throttle slider is **locked** when disarmed
|
||||||
|
- **Emergency stop** resets all values to safe state
|
||||||
|
|
||||||
|
### Technical Implementation
|
||||||
|
- **AsyncWebServer** for HTTP requests
|
||||||
|
- **WebSocket** communication for real-time data
|
||||||
|
- **JSON** message format for data exchange
|
||||||
|
- **WiFi SoftAP** mode for standalone operation
|
||||||
|
- **Automatic client cleanup** prevents memory leaks
|
||||||
|
|
||||||
|
### ⚠️ Known Issus
|
||||||
|
Make sure you are using these libraries for [ESPAsyncWebServer](https://github.com/ESP32Async/ESPAsyncWebServer) and [AsyncTCP](https://github.com/ESP32Async/AsyncTCP) to use "web_control.ino" example sketch.
