and conversions to other media types.
|
||||||
|
|
||||||
|
"Work" shall mean the work of authorship, whether in Source or

|
Object form, made available under the License, as indicated by a
|
||||||
|
copyright notice that is included in or attached to the work

||||||
|
(an example is provided in the Appendix below).
|
||||||
|
|
||||||
|
"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
|
||||||
|
represent, as a whole, an original work of authorship. For the purposes
|
||||||
|
of this License, Derivative Works shall not include works that remain
|
||||||
|
separable from, or merely link (or bind by name) to the interfaces of,
|
||||||
|
the Work and Derivative Works thereof.
|
||||||
|
|
||||||

|
designated in writing by the copyright owner as "Not a Contribution."
|
||||||
|

|
|
||||||
|
2. Grant of Copyright License. Subject to the terms and conditions of
|
||||||
|
this License, each Contributor hereby grants to You a perpetual,
|
||||||
|
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||||
|
copyright license to reproduce, prepare Derivative Works of,
|
||||||
|
publicly display, publicly perform, sublicense, and distribute the
|
||||||
|
Work and such Derivative Works in Source or Object form.
|
||||||
|
|
||||||
|
3. Grant of Patent License. Subject to the terms and conditions of
|
||||||
|
this License, each Contributor hereby grants to You a perpetual,
|
||||||
|
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||||
|
(except as stated in this section) patent license to make, have made,
|
||||||
|
use, offer to sell, sell, import, and otherwise transfer the Work,
|
||||||
|
where such license applies only to those patent claims licensable
|
||||||
|
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
|
||||||
|
modifications, and in Source or Object form, provided that You
|
||||||
|
meet the following conditions:
|
||||||
|
|
||||||
|
(a) You must give any other recipients of the Work or
|
||||||
|
Derivative Works a copy of this License; and
|
||||||
|
|
||||||
|
(b) You must cause any modified files to carry prominent notices
|
||||||
|
stating that You changed the files; and
|
||||||
|
|
||||||
|
(c) You must retain, in the Source form of any Derivative Works
|
||||||
|
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
|
||||||
|
as part of the Derivative Works; within the Source form or
|
||||||
|
documentation, if provided along with the Derivative Works; or,
|
||||||
|
within a display generated by the Derivative Works, if and
|
||||||
|
wherever such third-party notices normally appear. The contents
|
||||||
|
of the NOTICE file are for informational purposes only and
|
||||||
|
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
|
||||||
|
for any such Derivative Works as a whole, provided Your use,
|
||||||
|
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-intel-gpio
|
||||||
|
========================
|
||||||
|
|
||||||
|
A <a href="http://nodered.org" target="_new">Node-RED</a> node to talk to an Intel
|
||||||
|
Galileo or Edison running mraa.
|
||||||
|
|
||||||
|
Install
|
||||||
|
-------
|
||||||
|
|
||||||
|
Run the following command in the root directory of your Node-RED install, usually
|
||||||
|
this is ~/.node-red .
|
||||||
|
|
||||||
|
npm install node-red-node-intel-gpio
|
||||||
|
|
||||||
|
Usage
|
||||||
|
-----
|
||||||
|
|
||||||
|
The Galileo or Edison must already be running Linux, and have Node-RED installed.
|
||||||
|
|
||||||
|
See the [Intel Downloads](https://software.intel.com/en-us/iot/home) for
|
||||||
|
hardware / downloads for you particular board.
|
||||||
|
|
||||||
|
Ensure the latest version of mraa libraries are installed: (version 1.5 as of Sept 2015)
|
||||||
|
|
||||||
|
echo "src mraa-upm http://iotdk.intel.com/repos/1.5/intelgalactic" > /etc/opkg/mraa-upm.conf
|
||||||
|
okpg update
|
||||||
|
opkg upgrade
|
||||||
|
|
||||||
|
**NOTE** : This node assumes that the mraa npm is already installed globally - as
|
||||||
|
it is on the Galileo and Edison boards.
|
||||||
|
|
||||||
|
If you do need to install Node-RED, you can do this as follows from the home directory of the root user
|
||||||
|
|
||||||
|
npm install -g --unsafe-perm node-red
|
||||||
|
mkdir .node-red
|
||||||
|
cd .node-red
|
||||||
|
npm install node-red-node-intel-gpio
|
||||||
|
|
||||||
|
###Analogue Input Node
|
||||||
|
|
||||||
|
Monitors the selected pin for changes. It outputs on a change of value.
|
||||||
|
As analogue inputs are continously changing you can set the sample rate in ms from 20 to 65535.
|
||||||
|
|
||||||
|
###Digital Input Node
|
||||||
|
|
||||||
|
Monitors the selected pin for changes. It only outputs on a change of value.
|
||||||
|
|
||||||
|
###Digital Output Node
|
||||||
|
|
||||||
|
Sets the selected digital pin output high or low depending on the value of
|
||||||
|
**msg.payload** - expects a number or string 0 or 1.
|
||||||
|
|
||||||
|
###Pulse Width Modulation (PWM) Node
|
||||||
|
|
||||||
|
The **msg.payload** should contain a floating point number value
|
||||||
|
between 0 (off) and 1 (fully on), or a string representation thereof.
|
||||||
|
|
||||||
|
You can set the overall period (mS) in the edit dialogue.
|
||||||
|
|
||||||
|
For servo control set the period to 20mS and vary the input between 0.05 and 0.10,
|
||||||
|
|
||||||
|
0.05 = 5% of 20mS = 1mS
|
||||||
|
0.75 = 7.5% of 20mS = 1.5mS - typical servo centre point
|
||||||
|
0.10 = 10% of 20mS = 2mS
|
||||||
|
|
||||||
|
###Example
|
||||||
|
|
||||||
|
Simple flow to blink Pin 13
