# LED Matrix Clock
|
||||
# LEDSportsMatrix
|
||||
|
||||
A simple, modular clock application for Raspberry Pi using Adafruit LED Matrix displays.
|
||||
A modular LED matrix display system for sports information using Raspberry Pi and RGB LED matrices.
|
||||
|
||||
## Hardware Requirements
|
||||
|
||||
- Raspberry Pi 3
|
||||
- 2x Adafruit 64x32 LED Matrices
|
||||
- Adafruit Pi LED Matrix Bonnet
|
||||
- Raspberry Pi 3 or newer
|
||||
- Adafruit RGB Matrix Bonnet/HAT
|
||||
- LED Matrix panels (64x32)
|
||||
|
||||
## Installation
|
||||
|
||||
1. Install required system packages:
|
||||
1. Clone this repository:
|
||||
```bash
|
||||
sudo apt-get update
|
||||
sudo apt-get install -y python3-pip python3-dev python3-setuptools
|
||||
sudo apt-get install -y build-essential git
|
||||
sudo apt-get install -y python3-pil python3-pil.imagetk
|
||||
sudo apt-get install -y cython3
|
||||
git clone https://github.com/yourusername/LEDSportsMatrix.git
|
||||
cd LEDSportsMatrix
|
||||
```
|
||||
|
||||
2. Install the rpi-rgb-led-matrix library and Python bindings:
|
||||
2. Install dependencies:
|
||||
```bash
|
||||
# Make sure you're in the main project directory
|
||||
cd ~/LEDSportsMatrix/rpi-rgb-led-matrix-master
|
||||
|
||||
# Build the C++ library first
|
||||
make
|
||||
|
||||
# Build and install Python bindings
|
||||
cd bindings/python
|
||||
sudo python3 setup.py install
|
||||
cd ../..
|
||||
|
||||
# Install the library files
|
||||
sudo cp -r lib/* /usr/local/lib/
|
||||
sudo cp -r include/* /usr/local/include/
|
||||
sudo ldconfig
|
||||
cd ..
|
||||
```
|
||||
|
||||
3. Install additional Python packages:
|
||||
```bash
|
||||
sudo python3 -m pip install pytz
|
||||
```
|
||||
|
||||
4. Install the DejaVu Sans font:
|
||||
```bash
|
||||
sudo apt-get install -y fonts-dejavu
|
||||
```
|
||||
|
||||
## 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
|
||||
pip3 install -r requirements.txt
|
||||
```
|
||||
|
||||
## Configuration
|
||||
|
||||
Edit the `config/config.json` file to customize:
|
||||
- Timezone
|
||||
- Display settings (brightness, dimensions)
|
||||
- Clock format and update interval
|
||||
1. Copy the example configuration:
|
||||
```bash
|
||||
cp config/config.example.json config/config.json
|
||||
```
|
||||
|
||||
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
|
||||
2. Edit `config/config.json` with your preferences
|
||||
|
||||
## Important: Sound Module Configuration
|
||||
|
||||
The LED matrix library is known to conflict with the Raspberry Pi's built-in sound module. To prevent issues:
|
||||
|
||||
1. Remove unnecessary services that might interfere with the LED matrix:
|
||||
```bash
|
||||
sudo apt-get remove bluez bluez-firmware pi-bluetooth triggerhappy pigpio

## 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)

- Use external USB sound adapters if you need audio
|
||||
- Run the program with `--led-no-hardware-pulse` flag (may cause more flicker)
|

|
||||
## Running the Clock
|
||||
|
||||
The program must be run with root privileges to access the LED matrix hardware:
|
||||
|
||||
```bash
|
||||
cd src
|
||||
sudo python3 display_controller.py
|
||||
```
|
||||
