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: GPIO13
    num_leds: 10
    pio: 0
    rgb_order: 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 (Required, enum): The chipset to apply known timings from.

    • WS2812

    • WS2812B

    • SK6812

    • SM16703

  • rgb_order (Required, string): The RGB order of the strip.

    • RGB

    • RBG

    • GRB

    • GBR

    • BGR

    • BRG

  • is_rgbw (Optional, boolean): Set to true if the strip is RGBW. Defaults to false.

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.
