plugin:       RPI GPIO
author:       Bas van Dijk
category:     system
version:      0.0.1

description:  Control the GPIO ports of a RPI

Features

• Write GPIO pin high/low
• Read GPIO pin high/low
• Set pullup / pulldown resistor on GPIO pin
• Write/read analog signal
• Write/read PWM signal

Hardware needed

• Raspberry Pi

Tested with

• Raspberry Pi

Troubleshooting

You might run into the following error:

GPIO Error: pigpio error -1 in gpioInitialise

This could mean DOMUSTO server has insufficient rights to access the GPIO ports on your RPI. In this case you have to run DOMUSTO server with root access.

sudo npm run dev

Pre-installation requirement

Install the pigpio C library

The pigpio Node.js package requires the pigpio C library V41 or higher.

Raspbian Jessie 2016-05-10 or newer comes with the pigpio C library pre-installed so it need not be manually installed.

Raspbian Jessie Lite 2016-05-10 or newer does not come with the pigpio C library pre-installed so it must be manually installed with the following commands:

sudo apt-get update
sudo apt-get install pigpio

The pigpio C library contains a number of utilities. One of these utilities is pigpiod which launches the pigpio C library as a daemon. This utility should not be used as the pigpio Node.js package uses the C library directly.

Installation instructions for the pigpio C library on versions of Raspbian prior to 2016-05-10 can be found here.

Installation

Execute in the domusto-server folder:

$ ./domusto.js plugin add basvdijk/domusto-gpio

Configuration

1. Add the section below to your config.ts
2. Set the desired pin configuration
3. Restart DOMUSTO

{
    id: 'GPIO',
    enabled: true,
    settings: {
        pins: [
            {
                pinNumber: 24,
                type: 'output',
            },
            {
                pinNumber: 18,
                type: 'input/NO',
                resistor: 'pullUp'
            }
        ]
    }
},

Example devices

// GPIO18
{
    id: 'RPIPIN18',
    enabled: true,
    role: 'output',
    name: 'IN 18',
    type: 'switch',
    subType: 'on/off',
    plugin: {
        id: 'GPIO',
        deviceId: 'GPIO18'
    }
},

// GPIO24
{
    id: 'RPIPIN24',
    enabled: true,
    role: 'output',
    name: 'OUT 24',
    type: 'switch',
    subType: 'on/off',
    plugin: {
        id: 'GPIO',
        deviceId: 'GPIO24',
    },
}

Reading the GPIO pin status from terminal

$ sudo apt-get install wiringpi

$ gpio readall
