Pi5Neo
Simplifying NeoPixel LED Control on Raspberry Pi 5 via SPI (GPIO 10)




Pi5Neo is a Python library designed to make controlling NeoPixel LED strips super easy and efficient on the Raspberry Pi 5 (or equivalent boards). Whether you're creating dazzling light shows, informative displays, or ambient lighting, Pi5Neo simplifies the process using the Raspberry Pi’s SPI interface for high-performance communication.
🌟 Key Features

Easy NeoPixel Control: Send commands to any NeoPixel LED strip connected to the Raspberry Pi 5’s SPI interface.
Smooth Transitions: Enjoy vibrant color transitions with rainbow effects, loading bars, blinking patterns, and more.
Optimized for Performance: Tailored for the Raspberry Pi 5, ensuring fast and reliable communication with NeoPixel strips.
Minimalistic API: A simple API lets you focus on creativity without worrying about low-level hardware details.
Flexible Configurations: Control various effects and animations by easily setting colors, durations, and brightness levels.

🚀 Installation
You can install Pi5Neo via pip:
pip install pi5neo

Requirements

Python 3.6+
spidev (automatically installed with Pi5Neo)

Hardware

Raspberry Pi 5 (or equivalent with SPI interface)
NeoPixel LED Strip (WS281x family)

📚 Usage
Pi5Neo makes it straightforward to set up and control your NeoPixel strip. Here's a simple example:
from pi5neo import Pi5Neo

# Initialize the Pi5Neo class with 10 LEDs and an SPI speed of 800kHz
neo = Pi5Neo('/dev/spidev0.0', 10, 800)

# Fill the strip with a red color
neo.fill_strip(255, 0, 0)
neo.update_strip() # Commit changes to the LEDs

# Set the 5th LED to blue
neo.set_led_color(4, 0, 0, 255)
neo.update_strip()

🌈 Examples
You can find more advanced examples in the examples directory. Here’s a quick showcase of some cool effects you can create with Pi5Neo:
Example 1: Rainbow Cycle
from pi5neo import Pi5Neo
import time

def rainbow_cycle(neo, delay=0.1):
colors = [
(255, 0, 0), # Red
(255, 127, 0), # Orange
(255, 255, 0), # Yellow
(0, 255, 0), # Green
(0, 0, 255), # Blue
(75, 0, 130), # Indigo
(148, 0, 211) # Violet
]
for color in colors:
neo.fill_strip(*color)
neo.update_strip()
time.sleep(delay)

neo = Pi5Neo('/dev/spidev0.0', 10, 800)
rainbow_cycle(neo)

Example 2: Loading Bar Effect
from pi5neo import Pi5Neo
import time

def loading_bar(neo):
for i in range(neo.num_leds):
neo.set_led_color(i, 0, 255, 0) # Green loading bar
neo.update_strip()
time.sleep(0.2)
neo.clear_strip()
neo.update_strip()

neo = Pi5Neo('/dev/spidev0.0', 10, 800)
loading_bar(neo)

⚙️ Configuration
You can configure Pi5Neo by passing in different parameters for the number of LEDs, SPI speed, and more:
Pi5Neo('/dev/spidev0.0', num_leds=20, spi_speed_khz=1000)


/dev/spidev0.0: SPI device path
num_leds: Number of LEDs in the NeoPixel strip
spi_speed_khz: SPI speed in kHz (default 800)
