RaspController

Control your Raspberry Pi with a user-friendly web interface.

Overview

RaspController lets you manage and monitor your Raspberry Pi remotely. Key features include:

• File Sharing: Easily share files from a designated public folder.
• Hardware and Software Monitoring: Track RAM, CPU, disk usage, and running processes.
• GPIO Control: Configure and manipulate GPIO pins directly through the interface.
• Service Discovery: Automatic device detection on your network using mDNS.

Technologies Used

• RoseDB (https://github.com/rosedblabs/rosedb): A fast and efficient embedded database for storing historical data, charts, and pin management.
• go-gpiocdev (https://github.com/warthog618/go-gpiocdev): Provides Go bindings to interact with Raspberry Pi GPIO pins.
• mdns (https://github.com/hashicorp/mdns): Implements multicast DNS (mDNS) for effortless service discovery.
• Fiber (https://gofiber.io/): A high-performance web framework for Go, powering the web interface.

Requirements

• Raspberry Pi: This project was initially designed for the Raspberry Pi, but it's versatile enough to run on other compatible devices.
• Operating System: Tested on Arch Linux ARM and Raspberry Pi OS, but should work on other supported distributions.
• vcgencmd (https://github.com/raspberrypi/utils): Required for certain functionalities.

Configuration

Customize RaspController's behavior using the conf.yml file:

JWT_SECRET: "your_strong_secret_key" # Replace with a secure key 
DB_DIR: "/tmp/rosedb"                # Path to store the RoseDB database
PORT: 8080                          # Port for the web server
JWT_EXPIRES_IN: 3600                # JWT token expiration time (seconds)
SHARE_DIR: "/home/rasp/public"      # Directory for shared files

API Routes

RaspController exposes a RESTful API (all routes prefixed with /api):

Information

• /api/info: Retrieve general system information (RAM, CPU, disk, etc.).
• /api/info/ps: List running processes.

GPIO

• /api/gpio: List used GPIO pins.
• /api/gpio/all: List available GPIO pins.
• /api/gpio/:id: Get details about a specific GPIO pin.
• /api/gpio/:id (PATCH): Update GPIO configuration (example JSON body):

  {
      "direction": "out", 
      "value": 1
  }

Installation

1. Create a project directory: e.g., /opt/raspc.
2. Transfer files: Place the RaspController binary and conf.yml in the created directory.
3. Set up systemd service: Copy the provided service file to /etc/systemd/system/ and enable it:

   systemctl enable --now raspc.service

4. View Logs: Access logs using journalctl -u raspc.

Additional Notes

• Consider security improvements like HTTPS and proxy authentication when exposing RaspController to the Internet.
• For detailed usage and customization, explore the project's source code repository.
