Worldsemi WS2812 (and compatible) LED controller
|
|
|
|
Driver bindings for daisy chains of WS2812 (and compatible devices
|
|
like SK6812, or Everlight B1414) LED controllers.
|
|
|
|
The PWM protocol is described here:
|
|
https://wp.josh.com/2014/05/13/ws2812-neopixels-are-not-so-finicky-once-you-get-to-know-them/
|
|
|
|
A 0 bit's pulse width is between 200 and 500 ns. A 1 bit's is
|
|
at least 550 ns, with 700 ns or so typical. Pixel order is GRB.
|
|
|
|
You can connect the device to either a GPIO on your SoC, or a SPI
|
|
MOSI line. Use the worldsemi,ws2812-spi.yaml or
|
|
worldsemi,ws2812-gpio.yaml bindings instead of this file after
|
|
making your choice.
|
|
|
|
Everlight B1414:
|
|
|
|
The specification of the Everlight B1414 LED controller is slightly different.
|
|
For the control signal (waveform) each bit is described with a 1.2 us pulse:
|
|
|
|
0 bit: 300 ns high and 900 ns low.
|
|
1 bit: 900 ns high and 300 ns low.
|
|
|
|
There is a +/- 80 ns tolerance for each timing.
|
|
|
|
The latch/reset delay is 250 us and it must be set using the reset-delay
|
|
property. The pixel order depends on the model and it can be configured
|
|
using the color-mapping property.
|
|
|
|
include: led-strip.yaml
|
|
|
|
properties:
|
|
reset-delay:
|
|
type: int
|
|
default: 8
|
|
description: |
|
|
Minimum delay to wait (in microseconds) to make sure that the strip has
|
|
latched the signal. If omitted, a default value of 8 microseconds is used.
|
|
This default is good for the WS2812 controllers. Note that despite the
|
|
WS2812 datasheet states that a 50 microseconds delay is required, it seems
|
|
6 microseconds is enough. The default is set to 8 microseconds just to be
|
|
safe.
