|
<p>Raspberry Pi node to drive a string of neopixel or ws2812 LEDs.</p>
|
|
<p>Defaults to a bar chart style mode using configured foreground and background colours.
|
|
It can also display a needle (single pixel) type gauge.</p>
|
|
<p>It can accept a number in <code>msg.payload</code> that can be either the
|
|
number of pixels, or a percentage of the total length.</p>
|
|
<p>If you want to change the foregound colour, you can send a CSV of <i>html colour,length</i>.</p>
|
|
<p>To set the background just send an <i>html colour</i> name.
|
|
<a href="http://html-color-codes.info/color-names/" target="_top">Here
|
|
is a list</a> of html colour names.<p>
|
|
<p>You can also select shift modes where a single colour pixel is added to either the start or the end of the strip.</p>
|
|
<p>The <i>nth</i> pixel is set by <code>msg.payload</code> with a CSV string <i>n,r,g,b</i>
|
|
<!-- <p>The whole strip is set by <code>msg.payload</code> with a CSV string <i>r,g,b</i> -->
|
|
<p>A range of pixels from <i>x</i> to <i>y</i> can be set by <code>msg.payload</code>
|
|
with a CSV string <i>x,y,r,g,b</i>
|
|
<p>By default, gamma correction is enabled but it can disabled which can be useful for working with low brightness levels</p>
|
|
<p><code>msg.brightness</code> can be used to dynamically set brightness level</p>
|
|
<p>The pixels data line should be connected to Pi physical pin 12, 32, 33 or 35. <b>Note:</b>
|
|
pins 12 and 32 are on the same channel, as are 33 and 35. If you want connect two neopixels then use pins
|
|
from different channels.</p>
|
|
<p>Note: this node may also conflict with audio playback.</p>
