<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 accept a number in <b>msg.payload</b> 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>The <i>nth</i> pixel is set by <b>msg.payload</b> with a CSV string <i>n,r,g,b</i>
|
|
<!-- <p>The whole strip is set by <b>msg.payload</b> 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 <b>msg.payload</b>
|
|
with a CSV string <i>x,y,r,g,b</i>
|
|
<p>The pixels data line should be connected to Pi physical pin 12 - GPIO 18. <i>Note:</i>
|
|
this may conflict with audio playback.</p>
