CircuitPython_RGBLED

CircuitPython driver for RGB LEDs. Works with native microcontroller pins, Adafruit Blinka, or the PCA9685 PWM driver.

Dependencies

This driver depends on:

Adafruit CircuitPython

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.

Installing from PyPI

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI. To install for current user:

pip3 install adafruit-circuitpython-rgbled

To install system-wide (this may be required in some cases):

sudo pip3 install adafruit-circuitpython-rgbled

To install in a virtual environment in your current project:

mkdir project-name && cd project-name
python3 -m venv .venv
source .venv/bin/activate
pip3 install adafruit-circuitpython-rgbled

Usage Example

Initialize a common-cathode RGB LED with three PWM-capable pins.

import board
import adafruit_rgbled

# Pin the Red LED is connected to
RED_LED = board.D5

# Pin the Green LED is connected to
GREEN_LED = board.D6

# Pin the Blue LED is connected to
BLUE_LED = board.D7

# Create a RGB LED object
led = adafruit_rgbled.RGBLED(RED_LED, BLUE_LED, GREEN_LED)

Initialize a common-anode RGB LED with three PWM-capable pins

import board
import adafruit_rgbled

# Pin the Red LED is connected to
RED_LED = board.D5

# Pin the Green LED is connected to
GREEN_LED = board.D6

# Pin the Blue LED is connected to
BLUE_LED = board.D7

# Create a RGB LED object
led = adafruit_rgbled.RGBLED(RED_LED, BLUE_LED, GREEN_LED, invert_pwm = True)

Set the RGB LED's color to a RGB Tuple (Red, Green, Blue).

led.color = (255, 0, 0)

Set the RGB LED's color to a 24-bit integer (in hex syntax), 0x100000.

led.color = 0x100000

Setting a common-anode RGB LED using a ContextManager:

import board
import adafruit_rgbled
with adafruit_rgbled.RGBLED(board.D5, board.D6, board.D7, invert_pwm = True) as rgb_led:
    rgb_led.color = (0, 255, 0)
