# LEDSportsMatrix
|
|
|
|
A modular LED matrix display system for sports information using Raspberry Pi and RGB LED matrices.
|
|
|
|
## Hardware Requirements
|
|
- Raspberry Pi 3 or newer
|
|
- Adafruit RGB Matrix Bonnet/HAT
|
|
- LED Matrix panels (64x32)
|
|
|
|
## Installation
|
|
|
|
1. Clone this repository:
|
|
```bash
|
|
git clone https://github.com/yourusername/LEDSportsMatrix.git
|
|
cd LEDSportsMatrix
|
|
```
|
|
|
|
2. Install dependencies:
|
|
```bash
|
|
pip3 install -r requirements.txt
|
|
```
|
|
|
|
## Configuration
|
|
|
|
1. Copy the example configuration:
|
|
```bash
|
|
cp config/config.example.json config/config.json
|
|
```
|
|
|
|
2. Edit `config/config.json` with your preferences
|
|
|
|
## Important: Sound Module Configuration
|
|
|
|
1. Remove unnecessary services that might interfere with the LED matrix:
|
|
```bash
|
|
sudo apt-get remove bluez bluez-firmware pi-bluetooth triggerhappy pigpio
|
|
```
|
|
|
|
2. Blacklist the sound module:
|
|
```bash
|
|
cat <<EOF | sudo tee /etc/modprobe.d/blacklist-rgb-matrix.conf
|
|
blacklist snd_bcm2835
|
|
EOF
|
|
|
|
sudo update-initramfs -u
|
|
```
|
|
|
|
3. Reboot:
|
|
```bash
|
|
sudo reboot
|
|
```
|
|
|
|
## Running the Display
|
|
|
|
From the project root directory:
|
|
```bash
|
|
sudo python3 display_controller.py
|
|
```
|
|
|
|
The display will alternate between showing:
|
|
- Current time
|
|
- Weather information (requires API key configuration)
|
|
|
|
## Development
|
|
|
|
The project structure is organized as follows:
|
|
```
|
|
LEDSportsMatrix/
|
|
├── config/ # Configuration files
|
|
│ ├── config.json # Main configuration
|
|
│ └── config_secrets.json# API keys and sensitive data
|
|
├── src/ # Source code
|
|
│ ├── display_manager.py # LED matrix display handling
|
|
│ ├── clock.py # Clock display module
|
|
│ └── weather.py # Weather display module
|
|
└── display_controller.py # Main entry point
|
|
```
|
|
|
|
## Performance Optimization
|
|
|
|
To reduce flickering and improve display quality:
|
|
|
|
1. Edit `/boot/firmware/cmdline.txt`:
|
|
```bash
|
|
sudo nano /boot/firmware/cmdline.txt
|
|
```
|
|
|
|
2. Add `isolcpus=3` at the end of the line
|
|
|
|
3. Save and reboot:
|
|
```bash
|
|
sudo reboot
|
|
```
|
|
|
|
For sensitive settings like API keys:
|
|
1. Copy the template: `cp config/config_secrets.template.json config/config_secrets.json`
|
|
2. Edit `config/config_secrets.json` with your API keys
|
|
|
|
Note: If you still experience issues, you can additionally disable the audio hardware by editing `/boot/firmware/config.txt`:
|
|
```bash
|
|
sudo nano /boot/firmware/config.txt
|
|
```
|
|
And adding:
|
|
```
|
|
dtparam=audio=off
|
|
```
|
|
|
|
Alternatively, you can:
|
|
- Use external USB sound adapters if you need audio
|
|
- Run the program with `--led-no-hardware-pulse` flag (may cause more flicker)
|
