@node-pigpio

pigpiod socket interface for node.js

Features

• Can run gpio program on Windows/Mac/Linux with remote gpio by pigpiod
• high level wrappers api for for I2C, SPI, Bit banging I2C
• Contains a lowlevel api with the same features as the original python library

Requirements

• Node 12.x or later
• install and run pigopid http://abyz.me.uk/rpi/pigpio/download.html

Usage

npm install @node-pigpio/devices

import { outputDevices, usingAsync } from '@node-pigpio/devices'

import LED = outputDevices.LED
;(async () => {
  await usingAsync(await LED(22, false), async (led) => {
    await led.blink({ onTime: 1000, offTime: 1000, repeat: 5 })
  })
})()

lowlevel api

npm install @node-pigpio/core

lowlevel API is the same feature as the original python library except that all requests are asynchronous.

import * as pigpio from '@node-pigpio/core'
;(async () => {
  const pi1 = await pigpio.pi() // pi1 accesses the local Pi's GPIO
  const pi2 = await pigpio.pi('tom') // pi2 accesses tom's GPIO
  const pi3 = await pigpio.pi('dick') // pi3 accesses dick's GPIO

  await pi1.write(4, 0) // set local Pi's GPIO 4 low
  await pi2.write(4, 1) // set tom's GPIO 4 to high
  await pi3.read(4) // get level of dick's GPIO 4
})()
