|
||||
|
||||
"Derivative Works" shall mean any work, whether in Source or Object
|
||||
form, that is based on (or derived from) the Work and for which the
|
||||
editorial revisions, annotations, elaborations, or other modifications

|
||||
by such Contributor that are necessarily infringed by their
|
||||
Contribution(s) alone or by combination of their Contribution(s)
|
||||
with the Work to which such Contribution(s) was submitted. If You
|
||||
institute patent litigation against any entity (including a
|
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
||||
or a Contribution incorporated within the Work constitutes direct
|
||||
or contributory patent infringement, then any patent licenses
|
||||
granted to You under this License for that Work shall terminate
|
||||
as of the date such litigation is filed.
|
||||
|
||||
4. Redistribution. You may reproduce and distribute copies of the
|
||||
Work or Derivative Works thereof in any medium, with or without
|

||||
that You distribute, all copyright, patent, trademark, and
|
||||
attribution notices from the Source form of the Work,
|
||||
excluding those notices that do not pertain to any part of
|
||||
the Derivative Works; and
|
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its
|
||||
distribution, then any Derivative Works that You distribute must

||||
include a readable copy of the attribution notices contained
|
||||
within such NOTICE file, excluding those notices that do not
|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed

||||
within a display generated by the Derivative Works, if and
|
||||
wherever such third-party notices normally appear. The contents
|
||||

||||
do not modify the License. You may add Your own attribution
|
||||
notices within Derivative Works that You distribute, alongside
|
||||
or as an addendum to the NOTICE text from the Work, provided
|
||||
that such additional attribution notices cannot be construed
|
||||
as modifying the License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and
|
||||
may provide additional or different license terms and conditions
|
||||
for use, reproduction, or distribution of Your modifications, or

|
||||
reproduction, and distribution of the Work otherwise complies with
|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify
|
||||
the terms of any separate license agreement you may have executed
|
||||
with Licensor regarding such Contributions.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,
|
||||
except as required for reasonable and customary use in describing the
|
||||
origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||
agreed to in writing, Licensor provides the Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||
implied, including, without limitation, any warranties or conditions
|
||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||
appropriateness of using or redistributing the Work and assume any
|
||||
risks associated with Your exercise of permissions under this License.
|
||||
|
||||
8. Limitation of Liability. In no event and under no legal theory,
|
||||
whether in tort (including negligence), contract, or otherwise,
|
||||
unless required by applicable law (such as deliberate and grossly
|
||||
negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a
|
||||
result of this License or out of the use or inability to use the
|
||||
Work (including but not limited to damages for loss of goodwill,
|
||||
work stoppage, computer failure or malfunction, or any and all
|
||||
other commercial damages or losses), even if such Contributor
|
||||
has been advised of the possibility of such damages.
|
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing
|
||||
the Work or Derivative Works thereof, You may choose to offer,
|
||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||
or other liability obligations and/or rights consistent with this
|
||||
License. However, in accepting such obligations, You may act only
|
||||
on Your own behalf and on Your sole responsibility, not on behalf
|
||||
of any other Contributor, and only if You agree to indemnify,
|
||||
defend, and hold each Contributor harmless for any liability
|
||||
incurred by, or claims asserted against, such Contributor by reason
|
||||
of your accepting any such warranty or additional liability.

node-red-node-pi-sense-hat-simulator
|
||||
====================================
|
||||
|
||||
A <a href="http://nodered.org" target="_new">Node-RED</a> node to simulate a
|
||||
Raspberry Pi Sense HAT.
|
||||
|
||||
This allows you to create flows that interact with a virtual Sense HAT without the actual
|
||||
hardware - whether you're running on a Raspberry Pi, a laptop or elsewhere.
|
||||
|
||||
Once a Sense HAT simulator node has been deployed, the web page that provides
|
||||
a UI to the simulator can be accessed by clicking the link in the node's info panel.
|
||||
|
||||
## Install
|
||||
|
||||
Run the following command in your Node-RED user directory (typically `~/.node-red`):
|
||||
|
||||
npm install node-red-node-pi-sense-hat-simulator
|
||||
|
||||
## Usage
|
||||
|
||||
### Input Node
|
||||
|
||||
This node sends readings from the various sensors on the Sense HAT, grouped into
|
||||
three sets; motion events, environment events and joystick events.
|
||||
|
||||
#### Motion events
|
||||
|
||||
*** The current version of the simulator does not support Motion events ***
|
||||
|
||||
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 `topic` is set to `motion` and the `payload` is an object with the
|
||||
following values:
|
||||
|
||||
- `acceleration.x/y/z` : the acceleration intensity in Gs
|
||||
- `gyroscope.x/y/z` : the rotational intensity in radians/s
|
||||
- `orientation.roll/pitch/yaw` : the angle of the axis in degrees
|
||||
- `compass` : the direction of North in degrees
|
||||
|
||||
#### Environment events
|
||||
|
||||
Environment events include readings from the temperature, humidity and pressure
|
||||
sensors. They are sent at a rate of approximately 1 per second. The `topic`
|
||||
is set to `environment` and the `payload` is an object
|
||||
with the following values:
|
||||
|
||||
- `temperature` : degrees Celsius
|
||||
- `humidity` : percentage of relative humidity
|
||||
- `pressure` : Millibars
|
||||
|
||||
#### Joystick events
|
||||
|
||||
Joystick events are sent when the Sense HAT joystick is interacted with. The
|
||||
`topic` is set to `joystick` and the `payload` is an object with the following values:
|
||||
|
||||
- `key` : one of `UP`, `DOWN`, `LEFT`, `RIGHT`, `ENTER`
|
||||
- `state` : the state of the key:
|
||||
- `0` : the key has been released
|
||||
- `1` : the key has been pressed
|
||||
- `2` : the key is being held down
|
||||
|
||||
|
||||
### Output Node
|
||||
|
||||
This node sends commands to the 8x8 LED display on the Sense HAT.
|
||||
|
||||
Commands are sent to the node in `msg.payload`. Multiple commands can
|
||||
be sent in a single message by separating them with newline (\n) characters.
|
||||
|
||||
#### Set the colour of individual pixels
|
||||
|
||||
Format: `<x>,<y>,<colour>`
|
||||
|
||||
`x` and `y` must either be a value from 0 to 7, a `*` to indicate the entire row
|
||||
or column, or a range such as `3-6`.
|
||||
|
||||
`colour` must be one of:
|
||||
|
||||
- the well-known <a href="https://en.wikipedia.org/wiki/Web_colors" target="_new">HTML colour names</a> - eg `red` or `aquamarine`,
|
||||
- the <a href="http://cheerlights.com/cheerlights-api/">CheerLights colour names</a>,
|
||||
- a HEX colour value - eg `#aa9900`
|
||||
- an RGB triple - `190,255,0`
|
||||
- or simply `off`
|
||||
|
||||
To set the entire screen to red: `*,*,red`
|
||||
|
||||
To set the four corners of the display to red, green (#00ff00), yellow and blue (0,0,255):
|
||||
|
||||
`0,0,red,0,7,#00ff00,7,7,yellow,7,0,0,0,255`
|
||||
|
||||
To set a 3-pixel wide column to purple: `4-6,*,purple`
|
||||
|
||||
|
||||
#### Rotate the screen
|
||||
|
||||
Format: `R<angle>`
|
||||
|
||||
`angle` must be 0, 90, 180 or 270.
|
||||
|
||||
#### Flip the screen
|
||||
|
||||
Format: `R<axis>`
|
||||
|
||||
`axis` must be either `H` or `V` to flip on the horizontal or vertical axis respectively.
|
||||
|
||||
#### Scroll a message
|
||||
|
||||
*** The current version of the simulator does not support displaying text ***
|
||||
|
||||
If `msg.payload` is not recognised as any of the above commands, it is treated
|
||||
as a text message to be scrolled across the screen.
|
||||
|
||||
If the text is a single character, it will be displayed without scrolling. To
|
||||
scroll a single character, append a blank space after it - `"A "`.</p>
|
||||
|
||||
The following message properties can be used to customise the appearance:
|
||||
|
||||
- `msg.color` - the colour of the text, default: `white`
|
||||
- `msg.background` - the colour of the background, default: `off`
|
||||
- `msg.speed` - the scroll speed. A value in the range 1 (slower) to 5 (faster), default: `3`
|
||||
|
||||
#### Set the screen brightness
|
||||
|
||||
Format: `D<level>`
|
||||
|
||||
`level` must be 0 (low) or 1 (high).

<p>Raspberry Pi Sense HAT Simulator input node.</p>
|
||||
<p>This node simulates readings from the various sensors on the Sense HAT,
|
||||
grouped into three sets; motion events, environment events and joystick events.</p>
|
||||
<p>Once deployed, the simulator can be accessed <a href="sensehat-simulator" target="_new">here</a>.</p>
|
||||
<p><b>Motion events</b> - <i>not currently supported by the simulator</i></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>

<p>This node sends commands to the 8x8 LED display on the Sense HAT simulator.</p>
|
||||
<p>Once deployed, the simulator can be accessed <a href="sensehat-simulator" target="_new">here</a>.</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.<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><b>Flip the screen</b></p>
|
||||
<p>Format: <code>R<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><b>Scroll a message</b> - <i>not currently supported by the simulator</i></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> - <i>not currently supported by the simulator</i></p>
|
||||
<p>Format: <code>D<level></code></p>
|
||||
<p><code>level</code> must be 0 (low) or 1 (high).</p>
