pigpio Daemon PWM LED
The rpi_gpio_pwm
platform allows to control multiple lights using pulse-width modulation, for example LED strips. It supports one-color, RGB and RGBW LEDs driven by GPIOs of a Raspberry Pi (same host or remote) or a PCA9685 controller.
For controlling the GPIOs, the platform connects to the pigpio-daemon, which must be running. On Raspbian Jessie 2016-05-10 or newer the pigpio
library is already included. On other operating systems it needs to be installed first (see installation instructions).
Configuration
To enable this platform, add the following lines to your configuration.yaml
:
# Example configuration.yaml entry
light:
- platform: rpi_gpio_pwm
leds:
- name: Lightstrip Cupboard
driver: gpio
pins: [17]
type: simple
Configuration Variables
Can contain multiple LEDs.
The pins connected to the LED as a list. The order of pins is determined by the specified type.
Examples
In this section you find some real-life examples of how to use this sensor.
RGB LED connected to PCA9685 controller
This example uses a PCA9685 controller to control a RGB LED.
# Example configuration.yaml entry
light:
- platform: rpi_gpio_pwm
leds:
- name: TV Backlight
driver: pca9685
pins: [0, 1, 2] # [R, G, B]
type: rgb
RGBW LED connected to PCA9685 controller
This example uses a PCA9685 controller to interact with a RGBW LED.
# Example configuration.yaml entry
light:
- platform: rpi_gpio_pwm
leds:
- name: Lightstrip Desk
driver: pca9685
pins: [3, 4, 5, 6] # [R, G, B, W]
type: rgbw
RGB LED connected to the GPIO pins of an remote Raspberry Pi.
On the Raspberry Pi the pigpio daemon is running on the default port 6666.
# Example configuration.yaml entry
light:
- platform: rpi_gpio_pwm
leds:
- name: Lightstrip Sideboard
driver: gpio
host: 192.168.0.66
