|
||||
1. **Hardware Requirements**
|
||||
- Raspberry Pi (any model with SMI support)
|
||||
- WS281x-compatible RGB LED strip
|
||||
- I2S microphone (for autonomous mode)
|
||||
- I2S microphone (for standalone mode)
|
||||
- Optional: MIDI controller
|
||||
|
||||
2. **Software Setup**
|
||||
- Install dependencies (see `requirements.txt`)
|
||||
- Configure network for ArtNet or connect MIDI controller
|
||||
- Access the web interface via your browser
|
||||
### System install
|
||||
|
||||
The project is design for running on top of [Raspberry Pi OS Lite 32bits](https://www.raspberrypi.com/software/) (formerly Raspbian).
|
||||
|
||||
Raspberry Pi OS Lite provides device access through file system, networking tools for network interface management, POSIX sockets, native threading, and process control, covering all system features needed by LightSabre.
|
||||
|
||||
What about Realtime ?
|
||||
|
||||
#### Network AP / infra
|
||||
|
||||
`sudo raspi-config`
|
||||
|
||||
See. `nmcli`
|
||||
`nmcli c up preconfigured`
|
||||
|
||||
|
||||
|
||||
#### Rust
|
||||
After installing Raspberry Pi OS we need to install Rust toolchain:
|
||||
```
|
||||
sudo apt update
|
||||
sudo apt full upgrade -y
|
||||
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
|
||||
```
|
||||
|
||||
