|
||||
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

|
||||
|
||||
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

|
||||
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
|
||||

|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,

|
||||
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-gpiod
|
||||
======================
|
||||
|
||||
An alternative pair of <a href="http://nodered.org" target="_new">Node-RED</a> nodes to interact with Pi GPIO using
|
||||
the <a href="http://abyz.co.uk/rpi/pigpio/pigpiod.html" target="_new">PiGPIOd</a> daemon that is now part of Raspbian.
|
||||
|
||||
The advantage is that it also talk to GPIO on a Pi that is remote as long as it is running the daemon, and also sharing pins works more cleanly as contention is handled by the multiple connections.
|
||||
|
||||
The disadvantage is that you must setup and run the PiGPIO daemon first.
|
||||
|
||||
## Requirements
|
||||
|
||||
PiGPIOd must be running on the pi. The easiest way to ensure this is to add the following line to your Pi `/etc/rc.local` file.
|
||||
|
||||
/usr/bin/pigpiod
|
||||
|
||||
**Note**: By default this will expose the daemon on TCP port 8888, which is obviously a **security vulnerability**. If you don't want or need remote access then you can start it in local mode only, (`-l` option), or restrict permissions to certain ip addresses, (`-n {ipaddr}` option). For example:
|
||||
|
||||
/usr/bin/pigpiod -l
|
||||
/usr/bin/pigpiod -n 192.168.1.10
|
||||
|
||||
See the <a href="http://abyz.co.uk/rpi/pigpio/pigpiod.html" target="new">instructions</a> for more details.
|
||||
|
||||
## Install
|
||||
|
||||
Run the following command in your Node-RED user directory - typically `~/.node-red`
|
||||
|
||||
npm install node-red-node-pi-gpiod
|
||||
|
||||
## Usage
|
||||
|
||||
**Note:** the pin numbers refer the physical pin numbers on connector P1 as they are easier to locate.</p>
|
||||
|
||||
### Input node
|
||||
|
||||
Generates a `msg.payload` with either a 0 or 1 depending on the state of the input pin.
|
||||
|
||||
##### Outputs
|
||||
|
||||
- `msg.payload` - *number* - the level of the pin (0 or 1)
|
||||
- `msg.topic` - *string* - pi/{the pin number}
|
||||
|
||||
##### Details
|
||||
|
||||
You may also enable the input pullup resistor ↑ or the pulldown resistor ↓.
|
||||
|
||||
### Output node
|
||||
|
||||
Can be used in Digital, PWM or Servo modes.
|
||||
|
||||
###### Input
|
||||
|
||||
- `msg.payload` - *number | string*
|
||||
- Digital - 0, 1 - set pin low or high
|
||||
- PWM - 0 to 100 - level from 0 to 100%
|
||||
- Servo - 0 to 100, 50 is centred.
|
||||
|
||||
*Hint*: The `range` node can be used to scale inputs to the correct range.
|
||||
|
||||
##### Details
|
||||
|
||||
Digital mode expects a `msg.payload` with either a 0 or 1 (or true or false),
|
||||
and will set the selected physical pin high or low depending on the value passed in.
|
||||
|
||||
The initial value of the pin at deploy time can also be set to 0 or 1.
|
||||
|
||||
When using PWM and Servo modes, the input value should be a number 0 - 100, and can be floating point.
|
||||
|
||||
In servo mode you can also preset the minimum and maximum pulse times as required by your servo in order to reach its full range. Minimum of 5mS, maximum of 25 mS - defaults to 10 and 20 mS respectively.
