<p>Raspberry Pi Sense HAT input node.</p>
|
|
<p>This node sends readings from the various sensors on the Sense HAT,
|
|
grouped into three sets; motion events, environment events and joystick events.</p>
|
|
<p><b>Motion events</b></p>
|
|
<p>Motion events include readings from the accelerometer, gyroscope and magnetometer,
|
|
as well as the current compass heading. They are sent at a rate of approximately 10
|
|
per second. The <code>topic</code> is set to <code>motion</code> and the
|
|
<code>payload</code> is an object with the following values:</p>
|
|
<ul>
|
|
<li><code>acceleration.x/y/z</code> : the acceleration intensity in Gs</li>
|
|
<li><code>gyroscope.x/y/z</code> : the rotational intensity in radians/s</li>
|
|
<li><code>orientation.roll/pitch/yaw</code> : the angle of the axis in degrees</li>
|
|
<li><code>compass</code> : the direction of North in degrees</li>
|
|
</ul>
|
|
<p><b>Environment events</b></p>
|
|
<p>Environment events include readings from the temperature, humidity and pressure
|
|
sensors. They are sent at a rate of approximately 1 per second. The <code>topic</code>
|
|
is set to <code>environment</code> and the <code>payload</code> is an object
|
|
with the following values:</p>
|
|
<ul>
|
|
<li><code>temperature</code> : degrees Celsius</li>
|
|
<li><code>humidity</code> : percentage of relative humidity</li>
|
|
<li><code>pressure</code> : Millibars</li>
|
|
</ul>
|
|
<p><b>Joystick events</b></p>
|
|
<p>Joystick events are sent when the Sense HAT joystick is interacted with. The
|
|
<code>topic</code> is set to <code>joystick</code> and the <code>payload</code>
|
|
is an object with the following values:</p>
|
|
<ul>
|
|
<li><code>key</code> : one of <code>UP</code>, <code>DOWN</code>, <code>LEFT</code>, <code>RIGHT</code>, <code>ENTER</code></li>
|
|
<li><code>state</code> : the state of the key:
|
|
<ul>
|
|
<li><code>0</code> : the key has been released</li>
|
|
<li><code>1</code> : the key has been pressed</li>
|
|
<li><code>2</code> : the key is being held down</li>
|
|
</ul>
|
|
</li>
|
|
</ul>

|
|
<p>Raspberry Pi Sense HAT output node.</p>
|
|
<p>This node sends commands to the 8x8 LED display on the Sense HAT.</p>
|
|
<p>Commands are sent to the node in <code>msg.payload</code>. Multiple commands can
|
|
be sent in a single message by separating them with newline (\n) characters. You must
|
|
use a function node or a change node (jsonata expression) when using the newline (\n)
|
|
character to create a payload containing multiple commands.<p>
|
|
|
|
<p><b>Set the colour of individual pixels</b></p>
|
|
<p>Format: <code><x>,<y>,<colour></code>
|
|
<p><code>x</code> and <code>y</code> must either be a value from 0 to 7, a
|
|
<code>*</code> to indicate the entire row or column, or a range such as <code>3-6</code>.</p>
|
|
<p><code>colour</code> must be one of:
|
|
<ul>
|
|
<li>the well-known <a href="https://en.wikipedia.org/wiki/Web_colors" target="_new">HTML colour names</a>
|
|
- eg <code>red</code> or <code>aquamarine</code>,</li>
|
|
<li>the <a href="http://cheerlights.com/cheerlights-api/">CheerLights colour names</a>,</li>
|
|
<li>a HEX colour value - eg <code>#aa9900</code></li>
|
|
<li>an RGB triple - <code>190,255,0</code></li>
|
|
<li>or simply <code>off</code></li>
|
|
</ul>
|
|
|
|
<p><i>Examples</i></p>
|
|
<p>To set the entire screen to red:</p>
|
|
<p><code>*,*,red</code></p>
|
|
<p>To set the four corners of the display to red, green (#00ff00), yellow and blue (0,0,255):</p>
|
|
<p><code>0,0,red,0,7,#00ff00,7,7,yellow,7,0,0,0,255</code></p>
|
|
<p>To set a 3-pixel wide column to purple:</p>
|
|
<p><code>4-6,*,purple</code></p>
|
|
|
|
<p><b>Rotate the screen</b></p>
|
|
<p>Format: <code>R<angle></code></p>
|
|
<p><code>angle</code> must be 0, 90, 180 or 270.</p>
|
|
<p>Example: <code>R180</code></p>
|
|
|
|
<p><b>Flip the screen</b></p>
|
|
<p>Format: <code>F<axis></code></p>
|
|
<p><code>axis</code> must be either <code>H</code> or <code>V</code> to flip on
|
|
the horizontal or vertical axis respectively.</p>
|
|
<p>Example: <code>FV</code></p>
|
|
|
|
<p><b>Scroll a message</b></p>
|
|
<p>If <code>msg.payload</code> is not recognised as any of the above commands,
|
|
it is treated as a text message to be scrolled across the screen.</p>
|
|
<p>If the text is a single character, it will be displayed without scrolling.
|
|
To scroll a single character, append a blank space after it - <code>"A "</code>.</p>
|
|
<p>The following message properties can be used to customise the appearance:</p>
|
|
<ul>
|
|
<li><code>msg.color</code> - the colour of the text, default: <code>white</code></li>
|
|
<li><code>msg.background</code> - the colour of the background, default: <code>off</code></li>
|
|
<li><code>msg.speed</code> - the scroll speed. A value in the range 1 (slower) to 5 (faster), default: <code>3</code></li>
|
|
</ul>
|
|
|
|
<p><b>Set the screen brightness</b></p>
|
|
<p>Format: <code>D<level></code></p>
|
|
<p><code>level</code> must be 0 (low) or 1 (high).</p>
|
|
<p>Example: <code>D1</code></p>
