## About ## About
REST API to access the Raspberry PI RGB LED Matrix over HTTP. This is a REST API to access the Raspberry PI RGB LED Matrix over HTTP.
**Note:** This webserver should _never_ be exposed to the outside of the system it's running on, since it's meant to be combined with the provided `SvelteKit` webserver to serve a GUI. Although it can still be run in standalone, please make sure you set up a firewall or other kinds of access rules to **forbid any connections** from outside of this machine (localhost). **Note:** This webserver should _never_ be exposed to the outside of the system it's running on, since it's meant to be combined with the provided `SvelteKit` [Webserver](../Webserver/) to serve a GUI. Although it can still be run in standalone (more on this [here](../Webserver/README.md)), please make sure you set up a firewall or other kinds of access rules to **forbid any connections** from outside of this machine (localhost).
## How to run ## Installation
1. Make sure you have Python version 3.9.* installed, as the library uses a now deprecated module and as it is the only version proven to work.
2. Download the main [library](https://github.com/hzeller/rpi-rgb-led-matrix)'s repository and follow the installation [instructions](https://github.com/hzeller/rpi-rgb-led-matrix/blob/master/bindings/python/README.md) for the python binding
3. Download repository with `git clone https://gitlab1.ptb.de/waltem01/Matrix.git`
4. Navigate to the API directory with `cd API/`
## Running
**Note:** Once run, you should not simply kill the process. Graceful shutdown is work-in-progress. **Note:** Once run, you should not simply kill the process. Graceful shutdown is work-in-progress.

## Description ## Description
This project is a two-part software solution designed to drive LED matrices. It leverages a [specific library](./API/deps/librgbmatrix.so), which is originally designed for controlling LED matrices. The project adds an additional layer of abstraction to this library, making it more accessible and easier to use. This project is a two-part software solution designed to drive LED matrices.

## Project Structure ## Project Structure
The project is divided into two main directories, each containing the necessary files for the [REST API](./API/) and the [webserver](./Webserver/) respectively. You might've noticed the links to these directories whenever they were mentioned. The setup instructions for each part are provided within their respective directories.

## Environment Variables
The project is configured using optional environment variables. You will find project-wide variables here in [`.env.example`](./.env.example) that both the [REST API](./API/) and the [Webserver](./Webserver/) use to configure your hardware configuration.
