可寻址LED#

介绍#

可寻址 LED 是一种可编程 RGB LED 灯条设备，它连接到 3 线端口，并允许您控制单个 LED（例如 WS2812/“NeoPixel” 型）以显示自定义颜色和图案。

This page uses address_led as the example Addressable LED’s name. Replace it with your own configured name as needed.

以下是可用方法列表：

  • set – Sets the Addressable LED strip’s colors.

  • clear – Turns the whole Addressable LED strip off.

构造函数 – 手动初始化和配置可寻址 LED。

set#

set sets the Addressable LED strip to provided values.

Usage:
address_led.set(data, offset)

参数

描述

data

A list of Color values. This includes predefined colors, hexadecimal integers, and web colors.

offset

（可选）LED 灯的起始索引。

 
# Create a sequence of colors: Red, Green, Blue

# Set the Addressable LED to the color_list sequence
address_led.set(color_list)

clear#

clear turns the whole Addressable LED strip off.

Usage:
address_led.clear()

参数

描述

此方法没有参数。

构造函数#

Constructors are used to create AddressableLed objects, which are necessary for configuring an Addressable LED.

AddressableLed#

AddressableLed creates an Addressable LED.

Usage:
AddressableLed(port)

范围

描述

port

The 3-Wire Port that the Addressable LED strip is connected to:

  • On the V5 Brain – brain.three_wire_port.x where x is the number of the port.
  • On a 3-Wire Expander – expander.a where expander is the name of the expander instance.

 
# Create an Addressable LED in Port A
address_led = AddressableLed(brain.three_wire_port.a)
