ws2812-gpt-lp 0.1.0

A library to control WS2812 LEDs using SPI on Orange Pi

WS2812-GPT-LP

This library allows you to control WS2812 LEDs using SPI on Orange Pi. Cette bibliothèque permet de contrôler les LEDs WS2812 via SPI sur Orange Pi.

Installation

pip install ws2812-gpt-lp

Usage

from ws2812_gpt_lp import WS2812

Configuration

num_leds = 8 ws2812 = WS2812(spi_bus=4, spi_device=0, num_leds=num_leds)

Set colors for 8 LEDs

colors = [ (255, 0, 0), # Red (0, 255, 0), # Green (0, 0, 255), # Blue (255, 255, 0), # Yellow (0, 255, 255), # Cyan (255, 0, 255), # Magenta (255, 255, 255), # White (0, 0, 0) # Black (off) ]

Send colors to LEDs

ws2812.send_colors(colors)

Change the color of the first LED to blue

ws2812.send_color(0, 0, 0, 255)

Turn off all LEDs

ws2812.send_off()

Set all LEDs to red

ws2812.send_to_all(255, 0, 0)

Close the SPI connection

ws2812.close()

Note

You must solder a 100nF capacitor between the VCC and GND of the WS2812 LEDs to avoid interference.
