|
<p>The background of the array can be configured using an 8x8 pixel sized
|
|
png image, or by specifying a single colour using an <code>r,g,b</code> triple.</p>
|
|
<p>A pixel is set by a <code>payload</code> containing a CSV string <code>x,y,r,g,b</code> .
|
|
<code>x</code> and <code>y</code> can be a single pixel <code>0</code> to <code>7</code>,
|
|
a range of pixels, eg <code>2-5</code>, or <code>*</code> to indicate the whole line.
|
|
Multiple pixels strings can also be sent as <code>x1,y1,r1,g1,b1,x2,y2,r2,g2,b2,...</code> .</p>
|
|
<p>Any msg with a <code>topic</code> identifies a 'sprite', which can then
|
|
be moved independently. A 'sprite' can be a single pixel or a group of pixels.</p>
|
|
<p>Setting <code>payload</code> to <code>0</code> will delete the sprite from the list.</p>
|
|
<p>Setting <code>payload</code> to <code>CLEAR</code> will clear the display to off, and delete any sprites.</p>
|
|
<p>Setting <code>payload</code> to <ode>DELETE</ode> will delete any sprites, and leave the background.</p>
|
|
<p>The brightness may be set by setting <code>payload</code> to <code>brightness,nn</code> where nn is 0 to 100.</p>
|
|
<p>The rotation may be set by setting <code>payload</code> to <code>rotate,rr</code> where rr is 0, 90, 180 or 270.</p>
