RP2040 PIO LED Strip

This is a component using the RP2040 PIO peripheral to drive most addressable LED strips.

light:
  - platform: rp2040_pio_led_strip
    name: led_strip
    id: led_strip
    pin: GPIOXX
    num_leds: 10
    pio: 0
    channel_colors: GRB
    chipset: WS2812B

Configuration variables

• pin (Required, Pin): The pin for the data line of the light.

• num_leds (Required, int): The number of LEDs in the strip.

• pio (Required, int): The PIO peripheral to use. If using multiple strips, you can use up to 4 strips per PIO. Must be one of 0 or 1.

• chipset (Optional, enum): The chipset to apply known timings from.

  • WS2812
  • WS2812B
  • SK6812
  • SM16703

• channel_colors (Required, string): The order in which the strip expects its color channels. List each of R, G and B exactly once, optionally with a single W in any position; for example GRB, BGR, GRBW, WRGB or RWGB. The value is case-insensitive. Including a W makes this a four channel RGBW strip.

• All other options from Light.

Manual Timings

These can be used if you know the timings and your chipset is not set above. If you have a new specific chipset, please consider adding support to the codebase and add it to the list above.

• bit0_high (Optional, Time): The time to hold the data line high for a 0 bit.
• bit0_low (Optional, Time): The time to hold the data line low for a 0 bit.
• bit1_high (Optional, Time): The time to hold the data line high for a 1 bit.
• bit1_low (Optional, Time): The time to hold the data line low for a 1 bit.
