**Simple • Secure • Universal Hardware Communication**

EDPMT is a revolutionary hardware communication library that provides a transparent, zero-configuration solution for controlling GPIO, I2C, SPI, UART, and other hardware interfaces. Built from the ground up with security, simplicity, and transparency in mind.

## 🌟 Key Features

### **🚀 Radical Simplicity**
- **Single Universal Method**: One `execute(action, target, params)` method for everything
- **Zero Configuration**: Automatic detection of transport, TLS, and hardware
- **Minimal Dependencies**: Only 2-3 required packages vs 15+ in traditional solutions
- **One File Deployment**: Complete functionality in a single transparent module

### **🔐 Security First**
- **Automatic TLS Encryption**: Self-signed certificates generated automatically  
- **HTTPS/WSS by Default**: Secure communication out of the box
- **Optional Let's Encrypt**: Easy integration with production certificates
- **No Hardcoded Secrets**: No API keys, UUIDs, or hash authentication needed

### **🎯 Complete Transparency**
- **Full Operation Logging**: Every action logged with clear timestamps
- **Linear Data Flow**: Simple `Client → TLS → Server → Hardware → Response`
- **Debug-Friendly**: Easy troubleshooting with comprehensive logs
- **Layer Separation**: Clean architecture with distinct responsibilities

### **🌐 Universal Access**
- **Cross-Platform**: Linux, Windows, macOS support
- **Multi-Language API**: Same interface for Python, JavaScript, curl, etc.
- **Transport Auto-Selection**: IPC (local), TLS (network), WSS (browser)
- **Hardware Abstraction**: Works with real hardware or simulators

- **Automatic TLS**: Secure communication with self-signed certificates.
- **Multi-Transport Support**: Supports Local IPC, Network TLS, and Browser WSS.
- **Hardware Abstraction**: Automatically falls back to simulators if real hardware is unavailable.
- **Zero Configuration**: Auto-detection of hardware and environment settings.
- **Comprehensive Web Interface**: Real-time control and monitoring.
- **Docker Support**: Easy deployment with hardware access.
- **Full Logging and Transparency**: Detailed logs for debugging and monitoring.

## Installation

To install EDPMT, follow these steps:

```bash
# Clone the repository
git clone https://github.com/stream-ware/edpmt.git
cd edpmt

# Set up for development
make dev-setup
```

For detailed installation instructions and troubleshooting, refer to the [Installation Guide](#installation-guide) section below.

## Usage

### Starting the Server

```bash
# Start the server in development mode with simulators
make server-dev-sim

# Or use the CLI directly
./bin/edpmt server --dev --hardware-simulators
```

### Accessing the Server

Once the server is running, you can access:
- **Web Interface**: `https://<host>:<port>` (default: `https://0.0.0.0:8888`)
- **REST API**: `https://<host>:<port>/api/execute`
- **WebSocket**: `wss://<host>:<port>/ws`
- **Health Check**: `https://<host>:<port>/health`

## Hardware-Agnostic Framework

EDPMT now features a hardware-agnostic framework with pluggable hardware interfaces. This allows dynamic setup of hardware during initialization, with fallback to simulators if real hardware is unavailable. Currently supported interfaces include:
- **GPIO**: Real (Raspberry Pi) and Simulated implementations.
- **I2C**: Real (SMBus) and Simulated implementations.
- **SPI, UART, USB, I2S**: Dummy implementations (to be expanded with real and simulated versions).

To run the server with simulated hardware:
```bash
make server-dev-sim
```

## Installation Guide

### Prerequisites

- Python 3.6 or higher
- Access to hardware (Raspberry Pi for real hardware interaction) or use simulators

### Steps

1. **Clone the Repository**:
   ```bash
   git clone https://github.com/stream-ware/edpmt.git
   cd edpmt
   ```
2. **Development Setup**:
   ```bash
   make dev-setup
   ```
3. **Running the Server**:
   - For development with simulators:
     ```bash
     make server-dev-sim
     ```
   - For development with real hardware:
     ```bash
     make server-dev
     ```

### Troubleshooting

- **Server Fails to Start**: Ensure no other process is using the default port (8888). Use the `--port` option to specify a different port.
- **Hardware Not Detected**: Verify hardware connections and permissions. Use `--hardware-simulators` flag to test with simulated hardware.
- **TLS Errors**: If you encounter certificate issues, use `--no-tls` to disable TLS temporarily for debugging.
